How often should I change the oil if I rarely drive my car?

[TravisAnn]

If you rarely drive your car, change the oil every 5,000 kilometers or every three months. Engine oil, motor oil, or engine lubricant is a substance enhanced with additives in base oil, mainly containing anti-wear additives, detergents, dispersants, and multi-grade oil viscosity index improvers. Engine oil is used for lubricating internal combustion engines. The main 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, neutralize acids produced from fuel and lubricant oxidation (detergents), improve piston ring sealing, and cool the engine by carrying away heat from moving parts.
