Why Oil Degradation Matters Over time, the additives in oil that provide detergency and dispersancy break down, losing their ability to keep contaminants in suspension. Its primary role is lubrication, creating a thin film between moving metal parts to prevent direct contact and the resulting friction.
It also seals the gaps between pistons and cylinders, maintaining compression, and helps cool the engine by absorbing and transferring heat away from combustion cycles. This results in the formation of sludge, a thick, tar-like substance that can clog narrow passages and starve critical engine parts of lubrication.
