Good afternoon dear friends! If you are the owner of Renault Logan, then I hasten to congratulate you right away - this article will definitely come in handy for you. For other motorists, it will also be clearly useful to familiarize yourself with its contents. We all know that the timely replacement of fresh oil is the key to long and successful engine operation. That's what we'll talk about today: Renault Logan oil, how to choose it correctly and other features of the replacement. By the way, earlier I published interesting material about what kind of oil I poured into over 90,000 km. And .
Brief for reference:
The following engines were installed on this car by the manufacturer:
- 1.6. liter K7M710, K7M800, with an increased piston stroke.
- 1.4 liter, which can have 8 or 16 valves.
The engine can consume up to 0.5 liters of oil per 1000 km, so sooner or later we will have to deal with topping it up. The manufacturer recommends a complete replacement.
According to the manufacturer's instructions, a 1.4 liter 8 valve unit requires only 3.35 liters of lubricant. At the same time, the volume of oil for a 1.6 liter one will need much more - as much as 4.80 liters. There are certain recommendations on the grade and manufacturer of the lubricant, which are provided by the Renault plant itself. This is ELF Evolution 5w40 or ELF Evolution 5w30.
Checking the oil level
Let's start with how to check the oil - is it still serviceable or has it been replaced for a long time? It is advisable to perform this operation on a cold engine. If it has recently worked, then it will take at least a 10-15 minute break for it to cool down and for the oil to glass into the crankcase. The vehicle must be parked on level ground or ground, otherwise the level will not reflect the actual situation. For measurement, a special probe is used, which is located near the cylinder head under the hood. 
The probe is first wiped with a dry rag, after which it is carefully inserted into its original place. After a few seconds, you can take it back and measure the mark that the oil border will leave. Its level should be between the "min" and "max" marks. If the oil is below the minimum mark, it means that it urgently needs to be topped up. It should retain a light brown, transparent tint. If it is too dark, it indicates depleted resource and pollution. The answer to the question of how many liters of lubricant you need to buy with a complete replacement will be the calculated indicator of the volume of the oil system in the engine. As you said, for Renault Logan it is either 3.35 or 4.8 liters.
Which product do you prefer
First, consider which oil recommended by the manufacturer is best suited for use in domestic conditions. To begin with, the recommended ELF lubricant is also a French brand. 5w30 products are energy-saving, as evidenced by the corresponding sticker on the package. 
Most of all, it is suitable for those power units that are not equipped with a turbine, have not been boosted and have not been operated at all, or have a small passed resource. It is for these cases that an oil with low viscosity at high temperature conditions is ideal. This type of engine oil provides a thin oil film, but for new engines this is enough, but it allows you to reduce fuel consumption.
But fairly worn engines are characterized by larger gaps that must be carefully filled, and for this the best oil is one that has a greater density. What should it be? The best solution would be a grade that is advised to use in used engines, forced and diesel engines. It is for these purposes that you need a lubricant that has a low viscosity at high temperatures. It is due to the increased viscosity that the oil film does not break, which allows you to slightly save the amount of oil consumed by the engine.
The concept of tolerance and post-control
Another interesting criterion is the so-called lubricant tolerance, which is part of the certification process for these products. This is a complex procedure, the result of which is a special certificate - on its basis, the manufacturer can make the appropriate marking on the label. This parameter is necessary precisely so that the lubricant manufacturer can compete with other plants. However, it cannot be said unequivocally that one or another variety is the only one suitable for a particular brand of car, as in this case for Renault Logan.
After the oil change has been made, it is necessary. It is desirable that it be slightly below the maximum mark. In the event of an overflow, the excess can be carefully poured off. If the control lamp does not go out immediately, do not panic - this is normal. Now you need to start the engine and let it idle for about 5 minutes, then check the oil level again. It remains to measure the mileage at which this happened and you can hit the road.
Be added to the number of subscribers to my blog, and I will also be grateful for the feedback among your circle of friends. Ahead of us is waiting for a large number of interesting materials on automotive topics. Bye!
1.4 and 1.6, which have a 16v system, need a timely oil change every 10,000 kilometers. Some owners do not follow these rules, which in turn leads to premature engine wear. To make the right choice of oil, find out how much you need to purchase for replacement, you should be guided by the Renault Logan special tolerance sheet. In this article we will talk about the procedure for changing the oil in 1.4 and 1.6 - 16v engines.
Selection procedure
The main criterion for the purchase is its viscosity. The use of a viscosity with a high index leads to a break in the oil film, especially in the cold season.
The volume of canisters varies from 1 to 5 liters, so you can easily get as many as you need for your car.
Of course, for new engines 1.4 and 1.6 - 16v can be used, which has a lower viscosity index. This is due to the fact that the gaps in the rubbing pairs of the new unit have minimum values, respectively, a more fluid lubricant can easily reach the place of increased load.
Also, you need to purchase a liquid with a low viscosity coefficient for engines that have undergone major repairs. As a rule, the mileage before the first replacement will be about 1 thousand kilometers, since this resource is considered a break-in.
But for engines 1.4 and 1.6 - 16v, which have passed about 100 thousand kilometers, engine oil must be filled in thicker, since the gaps between the rubbing parts are large. Accordingly, such a liquid will better protect the motor components and give a strong film in places of increased friction.
The purchase of motor fluid must be made in specialized stores that have certified goods. If you buy low-quality oils, you risk damaging Logan, which will lead to costly repairs to motor parts.
As a rule, experienced salesmen in large auto stores will tell you how much oil and which one is needed for your car. Usually an experienced owner knows what kind of oil is needed and how much to fill in his car.
There are special additives that significantly reduce friction and contribute to long-term operation of the motor at increased loads. Among them is molybdenum, which is supplied both separately and already in the canister. To know how much of this additive you need to fill in, you need to know the amount of fluid required for your engine.
Let's talk about the replacement procedure
Many Logan car owners decide to contact the service for such work related to changing engine fluid.
We recommend that you carry out the replacement yourself and control this process completely on your own. Such a process is not difficult, with the exception of some features that you need to know and observe during these works. To completely protect yourself, use tight clothing to avoid burns with hot liquid, since at the time of work, the Logan engine must be warmed up to operating temperature.
So, let's begin the procedures for replacing motor lubricant.
Stock up on rags, as this work is a very dirty process.
- First you need to provide access to the car from below, for this you can use a car lift or a garage overpass.
- Get close to the car and carry out the dismantling of the plastic crankcase protection. To do this, unscrew the three bolts in the front of the bumper, and then dismantle two more fasteners behind the protection. Pull the plastic casing towards the rear axle, thereby dismantling this element.
- The first step is to dismantle the oil filter, since its channel is located at the very top of the lubrication artery.
- Use a special oil filter remover, if you don't have one, you can use sandpaper. Wrapping this element around its axis with sandpaper, unscrew it counterclockwise.
Another way to unscrew the oil filter is to use a regular screwdriver to pierce the filter element and use it as a lever. First you need to put a special container in order not to pour hot oil on it.
- Lubricate the O-rings of the filter element and install it in place by hand-tightening.
- Unscrew the drain plug in the engine crankcase, then drain the waste fluid into a separate container. Wait until all the liquid has drained, only then replace the drain plug and the sealing ring on it.
Attention! Take care of the disposal of used grease in advance.
- Screw in the drain plug without pinching, otherwise the threads of the aluminum crankcase may be damaged.
- Install the crankcase protection, having previously cleaned the part of excess dirt. Perform the installation procedure in the reverse order of its removal.
- Open the Logan hood, then remove the filler plug on the valve cover. After selecting the desired volume of the canister, fill in the liquid in the amount necessary.
If you do not know how much to fill in, use a special guide to allow fluid volumes for 1.6 and 1.4 - 16v motors.
- To know how much you have already filled in, you need to use a special probe that is installed on the car. This dipstick is marked with marks that determine the required level of the volume of liquid to be filled.
- Set the level to the maximum threshold of the dipstick, then run the engine for a few minutes. After running the engine for a short time, turn it off and, after waiting for a while, check the level in order to know how much to add.
- Screw the filler cap into place, after which the work can be considered completed.
Follow the safety instructions to avoid injury.
Conclusion
Now you know not only what kind of oil and how much is needed for your pet, but also how to change it correctly with your own hands. Premature oil change leads to a better result, since wear parts do not remain in the lubricating medium. Buy high-quality components that have a certificate of conformity and approval for your car. To protect yourself from low-quality lubricant products, purchase parts from large auto parts stores.
Follow the oil viscosity parameter according to the time of year, so you will extend the life of your car. Do not delay with timely maintenance and carry it out every 10 thousand kilometers.
After reading this article, you can use it as a manual for doing maintenance yourself.
We perform work on changing the oil in the 8-valve Renault Logan / Sandero engine and the oil filter on an inspection ditch or overpass.
We carry out the replacement on a non-working warm engine, it is better immediately after the trip, until the oil has cooled down.
Remove the oil filler cap.
From the bottom of the car, we clean the oil pan around the drain plug from dirt.
We loosen the drain plug with a square "8".
We substitute a wide container for draining used oil, with a volume of at least 4 liters and, having unscrewed the plug manually, drain the oil.
Attention! Be careful - the oil is hot.
A steel washer is installed under the cork.
To prevent oil leakage from the oil pan, a thin layer of oil-resistant rubber is vulcanized over the surface of the washer hole.
We look at the puck. To prevent oil leakage from the oil pan, a thin layer of oil-resistant rubber is vulcanized over the surface of the washer hole. In case of damage to the rubber seal of the washer, replace the washer with a new one. Drain the oil for at least 10 minutes. We wrap and tighten the drain plug. We remove oil drips from the engine crankcase and protection of the power unit.
When changing the oil, the oil filter must be replaced.
We substitute the container under the oil filter. Unscrew (counterclockwise) the oil filter. If this cannot be done manually, loosen the filter with a puller.
Unscrew (counterclockwise) the oil filter. If this cannot be done manually, loosen the filter with a puller.
In the absence of a puller, we pierce the filter housing with a powerful screwdriver (closer to the bottom so as not to damage the engine fitting) and unscrew the filter using a screwdriver as a lever.
We clean the filter seat on the cylinder block from dirt and oil drips. Fill the filter with new engine oil about half its volume and apply engine oil to the filter o-ring.
We wrap the oil filter by hand until the sealing ring comes into contact with the cylinder block. Turn the filter another 2/3 turn to seal the connection. Pour 3.3 liters of engine oil into the engine through the oil filler neck. Close the oil filler cap.
We start the engine for 1-2 minutes. We make sure that the indicator of insufficient (emergency) oil pressure in the engine has gone out in the instrument cluster and there are no leaks from under the drain plug and filter.
We stop the engine. After a few minutes (so that the oil has time to drain into the oil pan), we check the oil level and bring it to normal. Tighten the oil filter and drain plug if necessary.
Timely oil change is necessary to reduce wear of engine parts, in addition, clogging of the lubrication system with friction products can lead to disruption of the normal operation of the engine and reduce the comfort of car operation.
On Renault Logan cars, eight-valve carburetor ICE Renault K7M1.6, Renault K7J 1.4, and sixteen-valve ICE K4M 1.6 are most often installed. Sixteen valve internal combustion engines have a slightly higher specific power and completeness of fuel combustion, eight valve ones are more reliable, cheaper and easier to operate. The standard resource of the Renault Logan engine is, with proper operation, 400 thousand km. Now it is important for us to distinguish between these engine models in terms of the volume of engine oil to be filled in:
- engine 1.6 16-valve (K4M) - 4.80 liters
- engine 1.4 8-valve (K7J) - 3.35 liters
- engine 1.6 8-valve (K7M) - 3.40 liters.
If the oil is changed without changing the oil filter, then these volumes are reduced by 0.3 liters. But, we recommend changing the oil and the oil filter at the same time, this is due not only to the cheapness of the filter (any filter will do) compared to the cost of the oil, but also to the dominance of the main criterion for oil wear - clogging by friction products.
It is recommended to change the oil in the Renault Logan 1.6 engine every 15 thousand km. Severe operating conditions accelerate oil wear, and replacement should be done every 8 thousand km. Severe operating conditions are usually understood as: driving without preheating the engine, operating a car at sharply changing temperatures (for example, in winter up to -35 * C, and in summer up to + 35 * C on one oil), a quick set of speeds, including uphill or during overload, etc.
By checking the oil level, you can also assess the need for an oil change. Engine oil should not have a black color and a burnt smell, otherwise it is time to change it. The plug for checking the oil level on a Renault Logan car is shown in the photo.
The manufacturer recommends using oils in the Renault Logan engine ELF Evolution SXR 5W40 or ELF Evolution SXR 5W30. But, you can use any high-quality synthetic oil that is suitable for the temperature range of the car: 5W-40, 5W-30, or even 0W-30 AM.
When changing engine oil, it is worth replacing the drain plug gasket and oil filter.
- The drain plug gasket code is 11026 5505R.
- An oil filter will do - 7700274177 or 8200768913 (both filters are interchangeable).
The procedure for changing the oil in a Renault Logan 1.6 car:
- Unscrew the oil filler cap.
- Substitute a container for old oil.
- Remove the engine protection on the sixteen-valve K4M 1.6 (on eight-valve ICE models, you can leave the protection on).
- Unscrew the drain plug (square by 9), do not drop it into the oil container. All work with used oil must be done with protective rubber gloves.
- Wait for the maximum oil drain.
- At this time, unscrew the old oil filter (you can use a special puller, sold in any store). You can unscrew the filter by hand, especially if you screw fine sandpaper onto the filter housing.
- Lubricate the O-ring and threads with fresh oil before installing the oil filter.
- Install the new filter into the housing and screw it into place. Tighten the threads by hand only, without the use of tools.
- Fit a new drain plug gasket (Code 1026 5505R) to the plug, and tighten the plug.
- Fill in new oil.
- The oil level should be just below the “MAX” mark.
- Don't forget to screw on the oil filler cap.
- We let the engine idle for 5 minutes, turn it off and check the oil level.
- The oil level should be slightly above the middle between the "MIN" and "MAX" marks.
- Inspect the installation sites of the filter and drain plug for leakage, if everything is normal, install engine protection. If leaks are found, retighten the threads.
- For the convenience of monitoring the quality of the oil and the condition of the internal combustion engine, we advise you to mark the mileage at each oil change.
Before filling in fresh oil, you can flush the engine with oil of the same brand. To do this, fill in one liter of oil, start the engine and let it run for several minutes, then turn off the engine and drain the oil. Rinsing should be carried out with the old filter, because, in this case, washed-out carbon particles and suspended metal powder will be removed along with the old filter.
Video instruction
The oil in a Reno Logan engine determines its performance. If all gears are thoroughly lubricated, then the possibility of damage is excluded. Otherwise, a "snowball" of problems begins, following one after another. Vehicle reliability begins with the right choice of oil.
System device
In general terms, the lubrication system is arranged as follows: there is an oil pump, which is equipped with a crankshaft drive ( timing mechanism), and he distills oil from the pallet to the highway. The first part installed in the trunk is oil filter- it is required change periodically. When the oil filter is clogged, the bypass valve opens, allowing oil to bypass the filter. If the pressure becomes redundant another valve is activated reduction. Through it, part of the liquid from the line goes into the sump.
With a lack oil pressure the switch contact opens, the indicator lights up. Diagnostic details include control probe- it is immersed in the engine tray. On motors K4M and K7M the probe is at different points.
List of important items and replacement process
You will need:
- Oil filler plug: items 7 and 1;
- Drain plug: located on the bottom of the engine sump;
- Oil filter housing: 19 and 6 respectively.
To unscrew the filter, need a puller. If it is not there, in the case closer to the bottom make a hole and then use an awl or screwdriver, like a lever. The filter is removed after draining the oil. Before installing a new filter, on the contrary, fill with oil.
The drain plug is unscrewed tetrahedron "on 8". There will be a washer under the cork. Replacement is allowed - a washer made of copper with an internal diameter 18 mm.
The original oil filter is suitable for all engines discussed here. Its Renault catalog number is 7700274177. Sellers, moreover, use the designation 7700274177FCR210134. Does Renault have a filter? 8200768913 also suitable. Good luck choosing.
What to pour and in what quantity
It is important to choose the right engine oil, otherwise the engine life may be reduced several times.
- For the K4M (16V) motor - 4.8 l, Elf Evolution SXR brand, viscosity 5W40;
- For 8-valve engines - 3.3 liters, brand Elf Evolution SXR, 5W30.
From the factory, the same oil will be poured into different Logan engines - Elf Excellium LDX 5W40. It's the W40, not the W30.
Intervals between replacements for different motors do not differ: it is necessary to carry out replacement once a year or after every 15 thousand km. Oil index W40 is more viscous than W30. And in the engine with mileage 150-200 thousand it is better to pour a more viscous material.
All materials listed above are made on a synthetic basis and refer only to "synthetics".
Different oils produced under the same brand can be mixed. For example, the W30 index at 100 degrees corresponds to the numbers "9.3-12.4", and the W40 index - "12.5-16.2". Make a choice.
Let's start the review by listing the quality classes according to ACEA. Any oil is suitable for Logan engines, if it belongs to "gasoline" class: A1, A2, A3, A5. That is, there are no restrictions here. But according to the API classification, you can use three types of materials: SL, SM, SN.
API oil quality classes
Now - as for the viscosity. You can use a simple table:
The temperature reaches:
- -30 Gr. C.: 0W40 and 0W30;
- -25 Gr. C.: 5W40 and 5W30, also 5W50 for older engines;
- -20 Gr. C.: 10W30, 10W40, 10W50;
- -15 Gr. C. and higher: 15W40, 15W50.
It is clear that the lower index material (5W below 10W) is more versatile. But it will also be more expensive.
What is better, Lada Largus or Renault Logan?
Largus is supplied with Renault engines of the K4M (16 cells) and K7M (8 cells) models.
Motorists use oil Excellium NF 5W40, but it will no longer be possible to switch to a lower viscosity, W30. Know that material with higher viscosity is stronger coking. Good luck choosing!
By the way, this motor bends the valve when the timing breaks.
Replacement step by step
Know that it is better to drain the oil after warming up engine. The pallet and the material itself will be heated at the same time - the temperature can reach 70-80 degrees. You must comply with the limit caution. For more certainty, you can disconnect negative terminal: take a flat key “10”, loosen the nut, remove the terminal.
Engine oil change K4M, K7M-K7J
When the terminal off, perform the following actions:
- The car is rolled into the pit, part of the body is covered with a cloth;
- Unscrew filler plug;
- The drain plug must be twisted as follows: perform 1-2 turns with a key. Then the cork is unscrewed by hand. It is better to substitute an empty container under the drain hole;
- Remember that the cork is puck you can't lose;
- Changing the filter to "16-valve", remove the crankcase protection. It is necessary to unscrew the six bolts located around the perimeter. Use the carob key "on 10";
- A puller is brought to the filter housing, dismantled. On the "8-valve" the puller is brought from above (from under the hood);
- Screw in the new filter hand, then a puller, but First, the filter cavity is filled with oil.
- The drain plug is put in place and twisted, the crankcase protection is returned to its place;
- New oil is poured through the top filler neck. In this case, a funnel made from a plastic bottle.
Traces of old oil should be wiped off immediately.
