How often should the engine oil and three filters be replaced?

[VonCalvin]

The engine oil and three filters should generally be replaced every 6 months. Here is some information about engine oil: 1. Introduction: Engine oil, also known as motor oil or engine lubricant, is a substance enhanced with additives in a base oil. 2. Composition: It mainly contains anti-wear additives, detergents, dispersants, and multi-grade viscosity index improvers. Engine oil is used for lubricating internal combustion engines. 3. Function: The primary functions of engine oil are to reduce friction and wear on moving parts, remove sludge (one of the functions of dispersants) and varnish (detergents) from the engine. It also neutralizes acids produced from fuel and lubricant oxidation (detergents), improves the sealing of piston rings, and cools the engine by carrying away heat from moving parts.
