which of these oils is better to pour into the tank ???
I want to try it and post the results
Two-stroke oil is added to diesel fuel to lubricate the parts of the power unit. A 2T standard grease for two-stroke diesel engines has similar characteristics to oil for any internal combustion engine. The main distinguishing feature is the composition of the first substance.
To lubricate the parts of the power unit, two-stroke oil in a mixture of diesel fuel is used.
Operational properties
The substance in question is developed on the basis of minerals. In order for the oil added to diesel fuel to have the required properties, the manufacturer uses various additives. The main properties of 2T oil experts include:
- good solubility;
- high anti-corrosion, anti-wear and lubricating properties.
2T substance for diesel engines must be completely burned. Otherwise, the volume of ash will be maximum. The oil added to the fuel colors it in the color of the additive. Using this characteristic, you can determine the presence of lubrication in the fuel.
If the diesel engine runs hard, it means that the injection advance adjustment has been violated or the fuel equipment has failed. If the above problems appear, you will need to seek help from specialists.
Another cause of stiffness in the operation of the power unit is associated with refueling with low cetane fuel. This indicator characterizes the flammability of the fuel. A low CC value indicates the time interval with which ignition is delayed (exceeds the norm).
Therefore, when the fuel-oil mixture ignites, a large amount of fuel is injected into the engine chamber, where the ignition process occurs. The power unit starts to work hard.
A similar procedure is carried out in winter in order to reduce the maximum level of fuel filterability temperature.

ICE malfunctions
Auto mechanics recommend adding two-stroke oil to low-quality diesel fuel in order to increase the CC. Such additives are necessary to soften the operation of 2T and 4T units. The first internal combustion engine, unlike the second, is not equipped with a special system that allows the use of 2T oil. The lubrication system in such a motor is associated with the addition of additives to the fuel.
Oil is added to the internal combustion engine, taking into account its model:
- manually;
- automatically.
The mixture is first added to the diesel fuel and then to the chamber. Due to insufficient amount of oil in diesel fuel, engine wear occurs. Overheating or jamming of the constituent elements of the mechanism are associated with an excess amount of the mixture, which contributes to:
- increase in the level of opacity of exhaust gases;
- the appearance of soot;
- power unit wear.
In the event of a malfunction in the fuel supply and ignition system, partial combustion of the mixture occurs. In this case, it is recommended to change the used oil.
It may be of poor quality, or diesel fuel was mixed with an additive in the wrong proportions. The consequences of such use of 2T oil include engine breakdown.
When preparing a substance for mixing with diesel fuel, you must follow the manufacturer's recommendations, strictly following his instructions. 2T internal combustion engines are sensitive to fuel quality.
Due to a violation of the fuel / oil ratio or the use of non-regulated additives and oil, engine performance deteriorates. When buying a two-stroke lubricant, it is recommended to consider the pour point. The value of this indicator is indicated in the operating instructions for the equipment.

Mixing compositions
With the help of 2T oil, it is possible to improve the quality of diesel fuel by increasing its lubricating properties. In this case, supplements have the following contraindications:
- Do not use two-stroke oil if the engine is equipped with a particulate filter. Otherwise, the filter resource will decrease.
- During the combustion of the lubricant, ash substances settle on the nozzles, which leads to their rapid failure.
- Due to the formation of deposits, glow plugs are ignited.
It is rare to find an improvement in the performance of the power unit when using 2T oil. This is due to the formation of sulfuric acid. Since the additive contains sulfur, experts do not recommend experimenting with mixing the compositions.
Otherwise, toxic sulfur oxides will be released with the exhaust gases. Since the latter substance is contained in the oil in large quantities, it is recommended to use a detergent additive and alkalis. The last component neutralizes acids. An untimely or rare oil change in a diesel engine contributes to the appearance of acids in it.
It is an erroneous opinion that 2T oil has a positive effect on engine wear. After its addition, the noise of the internal combustion engine is reduced. This eliminates the noise and vibration. Regular operation of the motor without the use of additives contributes to the formation of gaps and the appearance of knocking in the power unit.
Among motorists there are supporters and opponents of the idea of adding two-stroke oil to diesel fuel. Both positions are not unfounded, they have a sensible explanation on which side is the truth, let's try to figure it out.
According to the new standards, the requirements for diesel fuel have been tightened: it is necessary that the sulfur content be 0.05%. Plus, the composition of the fuel should include additives that increase the cetane number, as well as depressant-dispersant chemicals. This allows to reduce the amount of sulfur in diesel fuel, reducing its harmful impact on the environment. But unscrupulous manufacturers produce fuel without adhering to all the necessary standards; diesel fuel often contains various impurities that reduce its quality - this affects the operation of power units.
The reason for the harsh operation of the diesel drive may be the use of fuel with an insufficient cetane number. This parameter affects the ability of the mixture to ignite. With insufficient cetane number, the ignition period becomes too long, before ignition a large amount of fuel enters the combustion chamber - the fuel ignites throughout the entire volume of the combustion chamber, the pressure rises very sharply, and the engine will work hard. Adding engine oil to diesel fuel increases the cetane number, the drive starts to work better, motorists note the following changes:
- slightly reduced fuel consumption;
- the power unit runs quieter and softer;
- exhaust gases become cleaner.
Adding oil to a diesel engine makes the engine run smoother, but there are other factors to consider. Watch a video on adding motor oil to fuel:
Oil top-up required
Modern standards reduce the proportion of sulfur in fuel, many motorists believe that a decrease in this chemical element will lead to a deterioration in the lubricating properties of the fuel. Chemists took this fact into account and added a package of additives to the composition of the fuel. But most drivers, to improve lubrication, add two-stroke engine oil to diesel fuel.
2-stroke oils burn out completely inside the power unit, without the formation of soot and soot. Motorists determined how much oil needed to be poured to improve engine performance - a ratio of 1:200.
If you fill in diesel fuel of dubious quality, then the addition of 2-stroke engine oil in such an amount is justified. Do not be afraid of contamination of sprayers at the same time - the specified oil is designed to burn instantly.
There is another problem - there is an injection pump with a separate lubrication system and those that are lubricated directly with diesel fuel. The second type is installed in passenger cars. To lubricate the elements of the pump, diesel fuel with a high sulfur content is needed, reducing the mass fraction of this chemical element to European standards has reduced the lubricating properties of the fuel mixture. Therefore, it is necessary to add two-stroke oils to diesel fuel when the engine is running, especially at low temperatures. Keep in mind that imported diesel fuel does not contain paraffin, it contains oil. Domestic diesel fuel has paraffin because of its low cost and lubricity. By adding 2-stroke motor oil to domestic diesel fuel, you prevent paraffin crystallization at low temperatures, ensure quick engine start, and increase the low-temperature threshold for pumping fuel through the filter.
topping opponents
Diesel fuel manufacturers do not indicate the possibility of adding lubricants to the composition of their fuel. The use of two-stroke oil is contrary to the recommendations of dealers of cars with modern engines, manufacturers of such drives indicate that dilution of the fuel with any substances is unacceptable.
Most experts adhere to the position: the addition of motor oil to a diesel engine is permissible with respect to old engines equipped with shield nozzles and is unacceptable in new power units with multi-hole sprayers.
In drives with decent mileage, wear of engine elements is observed, gaps between friction pairs increase, adding oil will lead to an increase in fuel density, the amount of fuel leaking to the combustion chamber will decrease, worn-out pairs of engine elements will stop ringing, there is an illusion of improving engine performance. In this case, you can do without a general repair of the motor. But this effect is short-lived, the engine will eventually fail.
The addition of two-stroke oil to diesel fuel is unacceptable due to the difference in temperature between a diesel engine and a motorcycle. 2-stroke oils burn out completely in motorcycle engines, and in diesel engines they form products of incomplete combustion - carbon deposits form, nozzles coke, deposits settle on the particulate filter, turbocharger parts, and so on. An excessive increase in the cetane number causes a decrease in drive power, leads to an increase in fuel consumption, an increase in smoke.
Conclusion
The addition of motor oil to diesel fuel is very common among motorists, such actions allow the use of diesel fuel at fairly low temperatures, engine performance improves, the lubricating properties of the mixture increase, and dry friction of the drive elements is eliminated.
For modern engines, these manipulations can be fatal; the design of the motor is not designed to change the viscosity by adding oil. And in old worn-out drives, the effect of improving the operation of the power unit is illusory, the driver simply drags out time until a major overhaul, but the reasons for the hard operation of the motor are not eliminated. In addition, 2-stroke motor oils are designed for the operation of a motorcycle, and not a diesel engine, there are doubts whether the mixture will burn completely inside the engine or lead to an increase in carbon formation.
Which of the opinions to listen to, the motorist must decide, because the resource of the motor depends on his choice.
Is it possible to fill diesel engine oil in a gasoline engine?
What kind of oil should be poured into a diesel engine?
