Motor oil is used in engines to reduce loads (heating, friction, etc.). Turbocharged engines are quite sensitive to the quality of fuel and lubricants, and the maintenance of such a car requires large financial investments from its owner. Oil for gasoline turbocharged engines is a separate group of products on the market. It is forbidden to use a lubricant intended for conventional power units in turbine engines. It is recommended to use only those oils that are recommended by the engine manufacturer. The list of permitted lubricants in accordance with ACEA, API classification standards, as well as oil viscosity are indicated in the technical manual that is attached to each car.

Working principle

Let's get acquainted with the principle of operationturbocharged gasoline engine, and what kind of oil to fill in it, we will consider further. A motor of this kind is a device in which air is supplied to the cylinders by means of a turbine. The power of this engine is much higher than that of a conventional one. Its main feature is a turbocharger, consisting of a fan and a turbine. The supercharger (compressor) is connected to the exhaust system of the car, part of the exhaust gas settles on the turbine blade. The latter spins up due to the pressure that the exhaust gas creates and starts the supercharger fan. It pumps a large volume of pressurized air.

Gasoline turbocharged engine

As a result, the fuel burns better, and the power (performance) of the engine increases. As a result, with a smaller volume, such a motor has more horsepower than a conventional (atmospheric) and larger one. Thus, a gasoline engine equipped with a turbine increases its power by about thirty percent.

Operating Rules

Compliance with all of the following rules is a guarantee of engine durability:

  1. Timely maintenance: replacement of consumables and engine oil in turbocharged gasoline engines.
  2. After each start, it is recommended to warm up the engine for two minutes, and then start driving.
  3. It is not allowed to work at idle speeds exceeding the normalized values ​​for more than thirty minutes.
  4. When stopping after a long trip, do not immediately turn off the engine. Turn off the ignitionresolved after two or three minutes. This is the time needed for the turbocharger to cool down at idle.
  5. Use only good quality turbocharged gasoline engine oil and fuel material. Poor quality grease filled will soon require expensive repairs. In addition, be sure to monitor the amount of oil left in the tank after a trip.

Oil level

Turbo engine requires special care. The presence of sufficient lubrication in it ensures the effective functioning of bearings and other elements. If the oil level is low, the bearings break and wear out quickly. Frequent oil checks are of particular importance. If it is not enough, then it should be added. In case of high consumption of lubricant, find out the cause and fix the problem.

Oil change

What kind of oil to pour into a turbocharged gasoline engine? Some motorists claim that any quality. However, specialists and experts do not agree with them for the following reasons. Turbocharging operates at high temperatures and high rotational speeds of plain bearings. The latter work reliably at a temperature of +150 degrees. If it is higher, then there is a danger of rupture of the oil layer due to liquid oil. In addition, conventional motor oils oxidize at high temperatures, and their lubricating properties disappear. Therefore, a special oil for gasoline turbocharged engines is needed, i.e. it must be designed for engines with turbocharging.

About motor oil

It is poured into both the engine and the turbine, in which there is relatively little of it, but it is also subject to periodic replacement. Lubricant requirements are very high. It is important to know that the oil in the turbine is changed more often than in the engine. It is allowed to use only the highest quality fluid recommended by the car manufacturer. It is not worth saving on it, since an engine running on low-quality lubricant will quickly become unusable, and significant material investments will be required to eliminate the breakdown. Oils for gasoline turbocharged engines differ in their characteristics from those intended for a conventional engine. The reason is that it is subjected to increased loads and high temperatures during the operation of the turbine. In addition, it is forbidden to mix different types of lubricants. It is best to fill in the same brand of oil, which will significantly increase the life of the engine.

Which oil for turbocharged gasoline engines to choose?

Inflated requirements for a lubricant product are associated with the specifics of the turbo engine. The oil must retain its qualities at any temperature. In the presence of a turbocharged engine, this is of great importance. The axis that fixes the impellers of the turbocharging system is immersed in oil, which acts as a thrust bearing. Poor-quality lubrication quickly disables the turbine. Quality requirements are high, so the list of suitable products is small.

Lubricants

The best engine oil for turbochargedgasoline engines - this is synthetic, but you should definitely focus on the manufacturer's recommendations. It indicates the marking of oils according to the standards:

  • European ACEA. According to this gradation, all oils are divided into categories such as A / B, C, B. The first category is intended for passenger cars. In addition, they are divided into several classes: A1 / B1 A3 / B3 A3 / B4 A5 / B5, i.e. the larger the value of the number, the more ideal the product. It is recognized that this classification has more stringent requirements for the quality of the lubricant. Class A5/B5 recommended for turbocharged engines.
  • American API (most common and most popular). According to this classification, all lubricants are divided into groups: gasoline, having the letter designation S and diesel - C. These letters are the first, and the second after them determines the quality of the product, starting from A and ending with N. Lubricants of classes SM and SN are considered modern and intended for both turbocharged and multi-valve engines.

Depending on the style of driving, the characteristics of the oil are selected by viscosity, which varies with temperature. When cooled, oils thicken, when heated, they liquefy.

Compositions of motor oils

During the operation of a car, any brand of lubricants lose their properties. The frequency of their replacement depends on the type of engine and driving conditions. Acquire oil taking into account its class, as well as the engine model. Lubricants have different characteristics depending on the base and the presence of additives:

  • Mineral oroil - they are obtained as a result of the distillation of oil and its purification. They quickly lose their qualities, as they contain a large number of additives: paraffin, aromatic, naphthenic.
  • Synthetic - endowed with the best lubricant base with a minimum amount of additives. They have a long shelf life, save fuel, reduce friction of parts, and are not sensitive to overheating.
  • Semi-synthetic - an intermediate option between petroleum and synthetic, i.e. they have a mixed base.
Motor oil production

Mineral and semi-synthetic lubricants are not used in turbo engines due to the fact that they instantly lose their properties.

Additives, which are contained in several lubricant composition, have the following qualities:

  • dispersing;
  • detergents;
  • anti-wear;
  • anti-corrosion;
  • antioxidant;

Sometimes they have other qualities that make them suitable for turbocharged engines.

Which oil is best for turbocharged gasoline engines? Only synthetic oils are suitable for them. They are allowed to operate even at a temperature of minus fifty degrees. In addition, such oils are recognized as the most resistant to any aggressive influences. It is also important that the lubricant is designed specifically for turbo engines and is suitable for all parameters, requirements and tolerances for use in a particular engine.

Oil change

To make a turbine on a gasoline enginefunctioned for a long time, you should not save on the quality and quantity of the lubricant. Cheap and low-quality lubricant is not able to create the desired level of friction of the working elements. They quickly fail, i.e., they will need to be replaced with intensive use of the car. Experts advise, when purchasing a vehicle equipped with a turbine, to clean the entire system and change the lubricant. Mixing different oils is strictly prohibited. Otherwise, they lose their properties, and the effectiveness of the work will be negligible. A complete replacement of the lubricant, on the contrary, will enhance the protection of the turbine and protect against unwanted influences. It is recommended to change the oil after five or six thousand kilometers.

Increase lubricant change intervals:

  • frequent use of cars on dusty roads;
  • long driving at high speeds;
  • departure from the best temperature regime of the engine;
  • occasional car use;
  • repeated start of the engine at low temperatures.

Due to such operating conditions of the car, not only the characteristics of the lubricant suffer, but they can also have a negative effect on other complex units.
