An oil change consists of changing the oil, the oil filter, and the drain plug in the engine.
This varies with the type of vehicle and the frequency of use (number of kilometers per year, starting and stopping frequencies, etc.). However, it is generally advised to have an oil change every year or every 10,000-15,000 km.
Oil filter: This guarantees the engine’s cleanliness. The filter and drain plug should be replaced every time the oil is changed.
The fuel filter: This eliminates any dirt build up in the fuel (diesel or gas) and needs to be changed every two oil changes or as often as recommended in your manual.
The air filter: This ensures clean air and avoids a build up of debris in the engine. It must be checked every oil change and replaced every two oil changes.
Oil: This reduces the friction between the engine parts to avoid deterioration. This needs to be changed every oil change.
The oil is composed of a sequence of molecules that are situated between the moving metal parts. The molecules prevent direct contact between the metal parts and hence reduce the friction and damage of the engine. While the engine is used, the molecules wear down and gradually disintegrate to the point where the grease is no longer effective. Having the oil changed regularly allows you to avoid high costs with such repairs.
