Will I notice any difference in my car if I don't make frequent engine oil changes?

Not changing your car's engine oil regularly can significantly reduce the level of protection provided against engine deterioration.

Engine oil also acts as a reservoir for all kinds of by-products that form when the fuel burns, including soot, sludge, water and acidic material, as well as unburnt and partially burnt fuel.

At the same time, the stress placed on the oil during engine operation gradually depletes the components that determine the oil's performance.

Replacing the oil on a regular basis ensures that the right balance of components is present in it. It also removes waste materials that might otherwise result in increased deposit formation, corrosion of metal components and increased wear and tear of the engine.
