Do you want to travel in your car? Then you just need to know how to reduce fuel consumption? Check out the ranking of the best. The topic of saving becomes especially relevant when traveling abroad, where sometimes the price of fuel causes considerable surprise.
The video shows how you can save fuel:
Hurry up - make people laugh!
So. most faithful and useful way fuel economy, which took the first place in the ranking, does not mean driving too fast. The ideal speed at which you need to go is about 80 km / h.
In some modern companies those engaged in long-distance transportation use special driver training. They are introduced to theoretical course driving, designed to change the attitude of the motorist to the speed of movement.
Moreover, driving at a speed of 80 km / h compared to driving at a speed of 90 km / h will give a difference in time equal to only four minutes.
These are not just words, but calculations made by Mercedes-Benz experts.
Engine speed
The fourth method will help you learn how to reduce fuel consumption using own engine. In other words, you need to learn not to "twist" the motor. If you want to really save on fuel, then it is not recommended to increase the engine speed over 2000 rpm. Also, you should shift gears as soon as possible. For example, so that the 5th gear on a VAZ 2112 car falls at a speed of 50 km / h. A car of this brand has a 16-valve engine that allows you to use this mode.
Don't forget tire pressure
Fifth place is occupied by a not so common, but effective way. This is to ensure the correct pressure in the tires. Even automotive scientists have calculated that reducing pressure increases fuel consumption by 2%. And tires that do not pass over time have not yet been invented. Therefore, it is important to follow this matter and it is necessary to pump up tires not only for safe driving, but also to save fuel. And if you notice that your tires are lowered, then they are necessary.
Correct spark plug gap adjustment
The sixth place in the ranking is occupied by a savings method based on adjusting the gap in. This refers to the gap between the central and side electrodes of the spark plug. So it is advisable to increase it to one millimeter in order to ensure better combustion of the mixture in the cylinders.
To be precise, it is not necessary to immediately take on an increase in the gap. Often a simple check is sufficient. And on many cars, the gap between the candles is already one millimeter. But if it is less, then it should be increased.
No need to carry anything extra in the trunk and on the roof
Cargo in the trunk and on the roof also affects fuel consumption. Therefore, it is advisable to tidy up in the trunk and not carry too much with you. The more weight, the more gasoline will be consumed. Do you need it?
Unique way of "air" bag
The air bag method ranks eighth in the ranking. It's a little adventurous, but the effect is good. IN this case the air bag method involves following some other vehicle, trying to drive as close to it as possible. Thus, you find yourself in a zone of rarefied air or in the so-called "bag". It is clear that the air here will not put pressure on the car, and there will be a minimum of resistance. And the less resistance, the less fuel consumption will be.
How to save fuel on an injection engine
As you know, the injector is much more economical than a carburetor engine. But even in such engines the problem of increased fuel consumption is observed. And the ninth place in the ranking is occupied by a method associated specifically with injection engine. It implies a simple method. As they say, everything ingenious is simple. If on a normal carbureted engine 10% of fuel economy depends on the quality of the fuel, then on the injection it is all 50%. Therefore, it is always necessary in such cars, which is recommended by the manufacturer.
In addition, you should not self-regulate fuel system your car. Visit car service centers more often, where you should replace or clean all filters that become dirty over time. This is especially true for filters installed in the catalyst. Fuel consumption is most often increased due to a faulty catalyst. Remember this.
Sensors
Another way to save fuel involves checking the operation of the sensors. As you know, the incorrect operation of these components leads to a violation of the correct mixture formation and overheating of the motor. And this, in turn, contributes to the overspending of gasoline.
Most often, temperature sensors fail. intake manifold and coolant. As a result air-fuel mixture either too rich or too poor. And in both cases, this leads not only to excessive fuel consumption, but also to loss of power.
Often fail and position sensors throttle valve. As a result, engine control in acceleration mode is disturbed. Also, the mode does not work correctly. idle move, as there are incorrect data on the perceived load.
Special attention should be paid to incoming air sensors and flow rate sensors. Also in this case, an incorrect amount of air or incorrect data leads to increased fuel consumption.
And, of course, oxygen sensors. They need to be given special attention. If the lambda probe, as this sensor is also called, fails, this will lead to improper mixture formation.
Reduce fuel consumption in an automatic transmission
Timely diagnostics of the box blocking unit will help to reduce gasoline consumption on cars with automatic transmission. If it malfunctions, the automatic transmission control unit does not allow the transition to higher gears. You don't have to be a jack-of-all-trades to figure out that this leads to increased spending. In other words, under such a set of circumstances, it turns on emergency mode automatic transmission operation. It is he who does not allow the inclusion of gears above the second or third.
Don't drive in the rain if you can't!
Closed windows reduce fuel consumption
The next place in the ranking is occupied by a method that involves driving with the windows up. How will this affect fuel economy? And everything is simple. Rolling windows create air turbulence that increases the vehicle's rolling resistance. As a result, the consumption of gasoline increases. Although these are just some grams, but if such a ride is practiced every day, then a negative result will not be long in coming.
A clean carburetor is the key to fuel economy
The video shows how to clean a car carburetor:
What part of the car is most responsible for the consumption of gasoline? That's right, of course, the carburetor. If he has served his time, then it is better to replace it with a new one or clean it more often. Often lingers in the carburetor a large number of impurities and dirt. and the jets will help restore it normal work. And this will lead to real savings fuel.
OK it's all over Now! Is it possible to reduce fuel consumption by car if you know all the above methods and use them, depending on the situation? Of course you can.

Many factors affect fuel consumption. First of all, these are aerodynamics, power and engine thrust on low revs, as well as the resistance of the road surface. A lot of energy is spent on acceleration to cruising speeds, but then the force is spent solely on overcoming the resistance of the environment. Therefore, in order to reduce emissions harmful substances from exhaust pipe environmentalists recommend resorting to a simple mechanism for handling the gas pedal. You can press it only at the start, but after a speed of 30 km / h, light touches are enough. Then the engine will not spin up over 2500 rpm. And this is quite enough for life in the city.
Modern motors have good characteristics on the bottoms. Thanks to direct injection manages to reach 80% of torque at 1200 rpm. If the engine is also equipped with a variable valve timing system, then 80% of thrust is available even from 1000 rpm. And this means that for a smooth start and acceleration it is not required to gas. By the way, according to the standards of the average European cycle, acceleration to “hundreds” is carried out in 30 seconds, and such dynamics just occurs within the boundaries of 2000 revolutions.Keeping the engine from over-revving is not easy. If the vehicle is equipped with a manual mechanical box gears, you can smoothly release the pedal already at idling, and a motor equipped electronic injection, he will slightly raise the thrust so as not to stall. On new BMW models and MINI already has a driverless start system. In order to avoid unnecessary regassing, the electronics itself exposes correct level fuel supply.
The higher the better
But then you need to reach the highest gear as quickly as possible. At a speed of 30 km / h, it is necessary to turn on the fourth stage, and at 60 km / h, it is necessary to set the “sixth”. Then the engine will spin below 2000 rpm, fuel consumption will drop significantly. For example, at 3 thousand revolutions, 3.5 times more fuel is consumed than at 1500 revolutions.
Thus, driving at a speed of 50-60 km / h for top gear will reduce the consumption of a 1.6-liter engine to 4-5 liters per "hundred". This technique is useful when the fuel level is zero, when you need to reach the nearest gas station with all your might.
In addition, modern cars use the Start-Stop system, which automatically turns off the engine at forced stops. On the "old women" you can turn off the engine yourself. Standing in traffic jams and in front of traffic lights without a working power unit gives a total of another 5% fuel savings. But here we must remember that frequent starts harm the mechanics, and it is better to turn off the engine at stops lasting more than one minute.
Tires and aerodynamics
Well-inflated tires help save fuel. Many manufacturers in standard conditions it is recommended to inflate the "front" to 2.2 bar, and the rear wheels to 2.3 bar. This is the most comfortable pressure for R16 and R17 wheels. But many do not follow the tires for months, allow pressure to be released and forget that the tire sags on a loaded car, increasing the contact patch, which leads to increased wear and increased fuel consumption. Therefore, to travel with the family to the country with a simple belongings in the trunk, you need to increase the pressure in the tires. Each car model and wheel size has its own value. For example, on Focus II with 205/55 R 17 wheels, it is recommended to run in rear tires 2.8 bar. And at Ford Mondeo rear wheels 215/50 R 17 recommend pumping up to 2.9 bar. Then the contact patch of the wheels with the asphalt straightens up to standard values and will decrease by about 1.5 times compared to the minimum pressure threshold. As a result, rolling resistance on asphalt will decrease. And this is about 10% fuel savings. But before pumping the wheels, you need to look at the instructions.
"Recommended for specific car pressure can be found on special stickers, which are usually located on the gas tank flap, in the doorway or on the glove compartment, says the head of the promotion team trademark and internal communications of Nokian Tiers LLC Alexey Zayakin . “Following the automaker’s recommendations will have a positive impact on tire performance: grip, hydroplaning resistance, fuel efficiency and tire mileage.”
But most importantly, in order to avoid an increase in fuel consumption, the aerodynamics of the car must not be violated. A roof rack, ridiculous sports body kits and collective farm rear wings can significantly distort the passage of air flow through the car body. Turbulent eddies appear behind the stern, a zone is formed reduced pressure, which sucks the car back, preventing its movement. Now all cars are blown in wind tunnels, where engineers are trying to arrange the body so that the air flow is dumped and chaotic already far astern. The sedan is considered the most optimal body type in terms of aerodynamics.
In general, these simple tips can help save on gasoline. Tests of domestic magazines have shown that thanks to a set of these rules, it is possible to reduce the consumption of a 1.6-liter atmospheric motor on C-class cars with manual box gears and front-wheel drive up to 3.5-4 liters of gasoline per 100 kilometers. True, driving so economically is a lot of work.
A vehicle is a rather costly thing in terms of maintenance. If troubleshooting and periodic inspections are something that cannot be avoided, then the only way to reduce the cost of a car is to save fuel. More on this later in the article.
Through the application of a number of methods, car owners can reduce gasoline consumption by 15-60 percent and this is not about chip tuning. As practice shows, most of the fuel is burned in vain. Consider what needs to be done so that gasoline is used only for its intended purpose. True, the recommendations below are relevant only for those motorists who are confident in the good technical condition of their car. The bottom line is that many undetected faults provoke increased consumption fuel, so they must be eliminated.
don't gasp
Each sharp press on the gas pedal increases gas mileage tenfold. And it doesn't matter - in the city or on the highway, during acceleration, start or exit to top speed. A motorist can drive for many years powerful machines and never press the accelerator pedal to the floor. And vice versa - quite often, getting out on cars with a weak engine of 1.2-1.6 liters on a normal highway, we start to press the pedal to the floor, go close to the "maximum speed" in order to reach our destination faster.
If you often enter this mode and drive hundreds of kilometers in this style, then the consumption of any car increases catastrophically - right up to 17-18 liters of fuel per hundred kilometers. Speed generally dramatically increases fuel consumption, and this is understandable - air resistance increases. Moreover, its increase does not occur in direct proportion, but in fact in geometric.
It is worth noting that the economy mode for a modern car - in fifth, of course, gear - depends on the power and volume of the power unit. On average, it is 60-90 kilometers per hour.
correct gearshift
When driving on an automatic transmission, only one thing depends on the driver - to press the gas pedal as smoothly as possible, and the box switches itself. It is worth saying that the fuel consumption of cars with automatic transmission 10-15 percent more than cars with manual transmission.
Many drivers ask and even write down on paper and stick it on the "torpedo" - at what speed, what gear to turn on? "At 20 kilometers per hour the second, at 40 - the third and so on." This is all nonsense, since these figures depend on the power unit, car brand, road slope and other factors.
It is better to use a universal formula that is much easier to remember: we use first gear for starting, second for acceleration, third for overtaking, fourth for city driving, fifth for highway driving.
tire pressure
Automotive scientists have calculated that reducing the pressure in all tires by at least 0.1 atmospheres increases fuel consumption by 2-3 percent. As you know, there are no tires that do not let in over time. Even Rolls-Royce and Ferrari. The only difference is that "Bridgestone" on "superdiscs" needs to be pumped up in the conditions of our roads once a month, and "Taganka" on the disks of VAZ cars - once a week.
But to distinguish a tire with a pressure of 2.0 atmospheres from 1.2 atm. not everyone can see it, but a car owner with such flat tires at each gas station will spend an extra 150 rubles. If desired, you can save more on tires by keeping the pressure at 2.5 atmospheres, but then the movement will be slightly uncomfortable: small bumps on the road will be felt more. At a pressure of three atmospheres or more braking distances increases sharply.
Increasing tire pressure is very dangerous on slippery and wet road. IN winter time this method is simply unacceptable, since the cost of restoring a car after an accident will exceed fuel savings by several times.
car energy unloading
Air conditioning increases fuel consumption by approximately 15%. current heating rear window- about 5%. Included far, near, additional light, "stove" - by another 10-15%. Only one dipped beam is able to give an increase in consumption of up to one hundred grams of fuel per hundred kilometers.
choose the weather for travel
If you have the opportunity not to drive in rainy weather, do not drive, because water resistance eats fuel a little less than oncoming air flow. Especially puddles, even insignificant ones - they generally slow down the car as if it were behind rear bumper someone is holding. Therefore, if you are going to go somewhere far in the rain, get ready that you will have to pay 15% more for fuel than usual.
reduce idle speed
Ask a mechanic at a car service to reduce the idle speed of the engine from the standard 900-1000 to 500-600. It is advisable to do this after break-in vehicle, that is, after 15-20 thousand kilometers. This will not harm the power unit, but it will significantly reduce consumption. And in big cities, where you constantly have to stand in traffic jams, it is very important. The main thing is that the power unit works stably at idle and does not stall during a sharp release of gas, turning on the air conditioner or other powerful electrical load, during braking and depressing the clutch pedal.
When driving, the windows of the car must be closed.
If you're really into fuel economy, then remember that lowered windows create air turbulence that increases the car's rolling resistance, and therefore fuel consumption. A little, about one and a half percent, but if such a ride is practiced every day ... Therefore, if the supply ventilation works effectively in your car, blowing and there is no particular need to expose your face to the wind, keep the windows up.
properly load the car
IN long road every extra kilo luggage compartment That's about one extra kilometer. Well, as for the roof rack, it generally increases fuel consumption by 10-15%.
Fuel saving devices
It seems technical progress reached the most incredible areas of our lives. Until quite recently, it was even difficult for us to imagine that the market would be overflowing with a wide range of various technical tricks that are responsible for reducing the car's appetite.
One popular know-how that has emerged in the last few years is the engine ionizer. According to the developers, the design in the form of a small cylinder improves the performance of the power unit and reduces the amount of harmful impurities, thereby reducing fuel consumption. But experienced car enthusiasts argue that the motor ionizer is a new, expensive, interesting thing, but very doubtful.
Some notice that after installing the ionizer, the motor, even at low speeds, starts to work better. True, this does not affect the economy. In addition, with incorrect installation of the ionizer, there may be short circuit and even a vehicle fire.
The ignition amplifier is an older device. And its use is doubtful precisely because of the prescription of the invention. Ignition boost on older cars did take place. However modern automotive industry does not leave the need to use this device. If you still decide to try this device, it must be chosen carefully. Certain models overheat very quickly and cannot withstand stress. As a result, the engine stalls every 15-20 minutes.
Another trendy automotive “gadget” is the cavitator. Cavitators are able to split the composition of the fuel, thereby improving the operation of the power unit. Splitting with the help of a cavitator occurs as follows - an alternating change in pressure makes it possible to turn liquid into vapor only in certain zones. As a result, the fuel burns out completely, and the engine power increases. However, you can talk about real savings only if you wind at least a thousand kilometers on a car every day. Otherwise, the acquisition of the cavitator itself will pay off for a very long time.
Saving fuel on a car with magnets
Neodymium magnets have become quite common in recent years. The principle of their operation is that the magnetic field is able to split the composition of the fuel into elementary particles that burn better in the engine, allowing you to save fuel consumption by 20 percent. In practice, in best case, a neodymium magnet will turn out to be a useless device, and at worst, it will seriously harm the car's electronics.
How does the quality of gasoline affect its economy
Try to use quality fuel. This is a very important saving factor. For example, it is not recommended to use the 92nd gasoline, it is advisable to give preference to the 95th. Of course, the latter is about five percent more expensive, but at the same time it makes it possible to save 10-15 percent of fuel. It is also not recommended to visit unchecked gas stations, because there you can fill up poor quality fuel. This can lead to damage and the need to repair the vehicle. Consequently, the consumption will also increase.
What are the advantages of a diesel engine
Advantage diesel engines is low fuel consumption. It is actually 30 percent less compared to gasoline power units. You will immediately notice that you have become a rare guest at the gas station.
Many factors influence the consumption of gasoline - driving style, driving conditions, the presence or absence of Maintenance, as well as the operation of additional equipment. Listen to these simple tips, and saving fuel in a car will not affect driving comfort. You will be able to use gasoline efficiently, which means that you will be much less likely to stop at a gas station.
Here are the simple rules:
Fuel consumption depends on the engine oil used. The engine runs on a mixture of gasoline and air, which drives the pistons and other parts of the engine. The resulting resistance requires energy, and therefore fuel consumption. Engine oil provides lubrication of engine parts, the lower the viscosity it has, the easier it is to move and spend less fuel. Those who are thinking about how to save gasoline should pay attention to this important parameter. synthetic oil With low level viscosity allows you to reduce costs by 5-10%.
2. Gasoline consumption and additional equipment
Air conditioning, car radio, stove, headlights, wipers, satellite navigation and any other optional equipment, working in the passenger compartment, consumes fuel. Because of this, you spend 5-30% more gasoline, and this is a lot. Of course, otherwise the ride comfort will suffer, but sometimes it is better to sacrifice it. If you need to reach the refueling in emergency, turn off all additional devices.
3. Check the air filter
Your car's air filter should be checked regularly. If it is dirty, then less air passes through it, for this reason you use more fuel. In order to check its condition, put the filter in the light. When it stops transmitting light, it's time to replace it.
4. Use a fuel saver
By connecting the Fuel Shark device, you can significantly reduce gasoline consumption. The economizer is installed in the cigarette lighter socket, while fuel consumption is reduced by 30%, ride smoothness improves and engine acceleration increases. The device can also be used on diesel, injection and carbureted cars. It acts as an extra battery to help electrical system work more efficiently.

5. Slow down
Fast driving leads to excessive consumption of fuel. The higher the speed, the more you spend gasoline. This increases the number of revolutions of the engine, which requires a lot of energy. Start driving slower and you will immediately feel the difference in your spending.
6. Move smoothly
Optimum fuel consumption occurs with smooth and uniform motion cars. This tip will be especially useful for those who are thinking about how to save gas on the machine. Analyze your route and try to pass it without haste, without overclocking and hard braking. Each additional pressing of the accelerator pedal leads to an extra consumption of energy.
Use everything available features gearboxes, very often car owners for some reason forget about them. Choose the "economy" mode or select it depending on the roadway. Switching to neutral gear, you allow the transmission to cool down, which reduces energy costs. It is best to move off smoothly and without jerks. If your car is equipped with cruise control and the track is not loaded, use it. By maintaining a constant speed, you can also save a lot of fuel.
7. Try to slow down less
To budge stationary car it will take more energy than when it is moving, even if the speed is small. For this reason, traffic jams should be avoided, because it is in them that drivers often have to start. When approaching a traffic light, you can start braking in advance, then the car will not stop completely at the moment when the green signal lights up.
8. Close windows
At fast driving It's best not to open the windows. The fact is that air flows into the car and provide additional resistance. The engine needs more energy to maintain this speed, which means more fuel consumption.
9. Use heating
The more often the car is started and warmed up, the more fuel consumption will be. In the cold season, car owners have to warm up the engine. After a long stay in the cold, it is more difficult to start it, and this also negatively affects the condition of the equipment and its resource. In order to reduce gasoline consumption, special heating should be used. Some devices are powered by electricity, but stand-alone models are becoming more and more popular.
10. Winterize your engine
If the car warms up quickly, it will use less fuel. Thanks to special car blankets made of flame retardant materials, you will be able to keep warm longer. The engine will cool down more slowly, which is very useful when you have arrived somewhere for a short time and are going to hit the road again soon.
11. Choose mechanics
An automatic transmission consumes 10-15% more fuel than a manual one. If the question of how to save gasoline on mechanics is more relevant for you, you should consider that timely switching to downshift not only reduce the load on the engine, but also allow efficient fuel consumption.
12. Watch your tire pressure
Tire pressure affects gas mileage and should be checked before driving. There is nothing to worry about if it is 0.3 bar above the norm. This will slightly increase the pressure on the body and suspension parts, but will not affect the ride quality. The driver and passengers will not notice any changes. IN modern cars this parameter is monitored by the computer, in this case, fuel economy occurs without your participation.
13. Reduce vehicle weight
The less the car weighs, the less energy is needed to accelerate it. When you are just planning to buy a car, you should pay attention to its weight and take a closer look at lightweight models. Please note that with an increase in load of only 100 kg, fuel consumption increases by approximately 20%. Get rid of unnecessary things and junk if you store it in the trunk. Clean up and leave everything else in the garage.
If you seriously decide to optimize the fuel consumption, then you should start with diagnostics technical condition your vehicle. Your main enemy in terms of economy, as a rule, will be a dirty air filter. When this channel passes less air, an over-rich mixture is formed. As a result, we have an overspending of gasoline or diesel fuel. As a rule, automakers recommend changing such "consumables" every 15,000 km. However, this figure, of course, varies depending on the driving conditions. As a rule, drivers in densely populated cities and people who practice driving in dusty and dirty roads, should be changed air filters at least twice as often as prescribed by the instructions. This is especially true for owners of cars with turbodiesel units.
A significant savings effect can also be timely replacement spark plugs. It’s definitely not worth neglecting this advice, since worn out candles can provoke a number of breakdowns, most often the failure of the ignition coil. As a rule, the resource of standard nickel candles is about 15,000 km. However, there are also silver, iridium, yttrium and platinum candles with extended service life. Some of the models can cost ten times more than regular ones, but the "mileage" of the best of these products is increased by almost an order of magnitude compared to cheap analogues.
The next important component in the matter of efficiency is the characteristics car tires. Advice about what summer tires at positive temperatures, it is more economical than all-weather, and even more so winter, we will leave "Captain Obviousness". However, most of you have probably heard of this. important factor savings like correct pressure in tires. But what should this pressure be for the most economical and safe ride? First of all, definitely not lowered relative to the regulations indicated on the driver's door pillar or, more rarely, on the inside of the fuel filler flap. As a rule, for an average passenger car, a pressure of up to 2.2 bar is recommended for the wheels of the front axle and 2.4 bar for the rear. However, if there are several people in the cabin, the pressure in each of the wheels should be increased - again, by the values \u200b\u200brecommended by the automaker.
According to experts, reducing the pressure in all wheels by at least 0.1 bar will increase fuel consumption by about 2%. On the other hand, there is a common misconception that tires should be "pumped" a little to save fuel. Strictly speaking, the way it is - in this way you can reduce consumption by 3-5%. However, in this scenario, you will get a side effect in the form increased wear rubber, deterioration exchange rate stability and smooth running and, accordingly, an increase in the load on the suspension. As they say, it's up to you.
Your driving style also has a huge impact on actual fuel consumption. Main advice here - to avoid sharp starts and equally rapid braking. If your vehicle is equipped manual transmission, then it makes sense not to activate overdrive at low speeds, but at the same time try to switch "up" a little earlier than it happens with active driving. The universal advice is to maintain an average engine speed. In most cases, we are talking about 2500-3000 rpm.
And here is a simple "life hack" for owners of cars with a hydromechanical "automatic" - maintain higher gears. For this, there are different ways- from turning on the "Overdrive" button available in a number of models to activating the "Winter" (upshifting is carried out at lower crankshaft speeds), Eco-modes and modern systems"Start-Stop", automatically turning off the motor at stops. Sometimes it makes sense to also shift into higher gears in manual mode"automatic". Well, the Sport and Kick Down modes, as you know, do not contribute to fuel economy at all.
There is also a well-known and at the same time quite radical way to save fuel, alas, at the expense of your comfort. It's about turning off the air conditioner. Such a measure can reduce consumption immediately from 5 to 20%. While we don't encourage you to go to such extreme lengths, here's what you need to know. If you decide to compensate for the shutdown air conditioner opening windows, then be aware that such a measure will not allow you to seriously save money, especially when driving on high speeds. The fact is that with open and half-open windows, aerodynamics suffer - air flows entering the car will provide additional resistance to movement.
By the way, oh air currents. If you are serious about saving fuel, you should not make temporary and global change into the aerodynamics of the car. Even streamlined roof boxes from reputable manufacturers will increase the car's appetite by at least 1 liter when driving faster than 120 km/h. What can we say about the classic roof racks - here the consumption can increase much more seriously. You should not get carried away with all sorts of "collective farm" body kits, rear wings and deflectors that violate the aerodynamics calculated by factory engineers in the so-called wind tunnels.
And in conclusion, a few not quite obvious nuances of savings. Warm up your car before driving cold weather, even if the automaker does not recommend doing so. Engines modern cars really willing to work "cold", however, in this case, the electronics optimize working mixture by increasing fuel consumption. On average, you will burn at least 7% more fuel when driving on a cold engine. If, when the engine is warming up, you also activate the heating of the seats, windows, turn on the stove and headlights, the consumption will increase by at least 10%.
Do not try to exceed the speed limit on the highway. Even if your car is equipped modern transmission, allowing not to exceed the average engine speed, fuel consumption will still increase in this case, since the aerodynamic resistance will increase.
Monitor battery performance. With its constant "undercharging", the electronics will command the engine to recharge it frequently, thereby increasing fuel consumption.
And finally, minimize the mass of the car. Remember that every extra 50 kg of weight increases fuel consumption by an average of 1 liter for every 100 km. It is clear that you will not ride alone all the time. However, you can easily remove unnecessary trash from the trunk, refuel fuel tank not completely, use lightweight wheel disks(forged as an option), replace the battery with a lighter one, and with a strong desire to subject the car to moderate tuning, install lightweight exhaust system, seats, suspension elements, etc. Latest measures, however, already extreme, for enthusiasts. Be that as it may, if you follow at least part of the above tips, you will notice that you stop at gas stations much less often than you used to.
