Q: What is the importance of regular oil and filter changes for home mechanics on Mercury Lynx?
A: One should always change oil regularly to avoid premature wear of engines. Be sure you have the necessary tools at hand and old rags. Lift the car higher up. Start the engine, let it warm up, and park on a plane surface. Jack stands should be used to raise the vehicle, drain pan placed under the oil drain plug. Remove plug, allow all oil to drain out then inspect for metal particles. Reinstall the plug securely. Slide the drip pan under the oil filter and loosen it enough to get it off. Clean the mounting surface, compare old and new filters, lube the new filter gasket, and screw it on by hand.
