Changing the oil in the Mercedes engine

The procedure for changing engine oil is carried out with the simultaneous replacement of the oil filter. It is carried out at the scheduled maintenance complex, during express maintenance or after some types of engine repairs. To replace the engine oil and filter, we use original or equivalent consumables certified by the manufacturer. Mercedes oil replacement is covered by a lifetime warranty.

Why you need to change engine oil

The lubricating fluid effectively reduces the friction of the moving parts of the engine, protects its surfaces from overheating and oxidation, and constantly removes excess heat. But it does this only until it is saturated with wear products, soot particles, and does not rust from contact with crankcase gases.

The longer the oil "works" in the crankcase, the worse it performs its functions. To extend the life of the engine and maintain its high efficiency, a scheduled replacement of the lubricant and its filter element is carried out.

If you do not change the “exercise” for a new lubricant in time, the engine overheats, friction appears in the friction pairs, and the overall wear of the engine increases. Without regular relubrication, the assembly will not work properly and may jam.

The maintenance program for Mercedes diesel cars provides for a shorter relubrication interval: about 10 t.d. for a car with a gasoline engine - 15 t. Km. .

The readings of the system directly depend on the state of the engine oil: its transparency, viscosity, operating temperature. Long-term operation of the engine at high speeds, heavy loads on the engine at low speeds and overheating - accelerate the "production" of the lubricating fluid and significantly reduce the service interval.

How to choose the right consumables

For each Mercedes engine model, the manufacturer provides for the use of engine oil of a certain viscosity containing a certain package of "additives".

Specifications of original Mercedes oils:

For AMG series and diesel engines with DPF filter - 229,51 MB SAE 5W-30 (A0009899701AAA4).

For diesel engines without a particulate filter and most gasoline engines: 229,5 MB SAE 5W-30 (A0009898301AAA4).

For most turbocharged petrol or diesel engines without DPF filter (except AMG series): All Weather, 229,3 MB SAE 5W 40 (A0009898201AAA6).

The configuration of the service system of modern Mercedes does not allow the use of lubricants of a different class. An attempt to save money, as well as the “chase” for expensive “better” consumables, can turn into a trip to the service on a tow truck.

There are a number of restrictions on the use of low-temperature (or high-temperature) synthetic-based low-viscosity fluids in worn-out automobile engines that have exceeded warranty mileage or have high "carbon" oil consumption.

When choosing a lubricant class, it is necessary to take into account the condition of the car engine and the seasonal conditions of its operation.
