HOW MOTOR OIL HELPS KEEP ENGINES RUNNING CLEAN

摘要

As anyone who has even a small amount of experience working on engines knows, regular oil changes are one of the most important things that can be done to extend the life of an engine. Premium quality motor oil such as Pennzoil will maintain its effectiveness over the life of the oil drain, allowing it to help in keeping the engine clean.rnAdditive packages are added to motor oil and play a key role in helping to keep an engine clean and protected from varnish and sludge, as well as wear from heat and acids. Additives can consist of anti-wear agents, friction modifiers, dispersants, detergents, viscosity index improvers and antioxidants.
