The primary use of motor oil is to ensure the constant lubrication of moving parts inside your engine. It limits friction between these parts, reducing heat production (loss of performance), and reducing premature wear of engine components.
Changing the Oil
Without frequent oil changes, dirt and sludge can build up in the engine, and old, dirty oil won't lubricate the moving parts as well as new, fresh oil will.
Necessity and frequency of oil changes has always been one of question and we feel the best course of action in any case is to always refer to the manufacturers owner’s manual for proper intervals and recommendations.
Benefits to regular oil changes are an extension of the life of the vehicle's engine itself and in the long run, saving you money in larger, more expensive repair bills. If the ‘check oil’ light comes on, it’s a good indication the vehicle is low on oil and that can be done without the assistance of a mechanic. However, if the light stays on or comes on right after topping it off, that is a good indication of a leak and a mechanic should look at the vehicle.
