The lubrication system is an integral part of every piston combustion engine and is absolutely necessary for engine lubrication and, thus, smooth engine operation.

Without lubricating the engine with oil, the engine would not be able to function, or it could, but only for a short time.

An oil filter is a type of filter designed to remove impurities from engine oil. Oil filters are used in car engines, aircraft, and marine engines.

If we are talking about cars, this filter is located in the lower or middle part of the engine.
