At what percentage does the engine oil require maintenance?
1 Answers
Engine oil cannot display its quantity; the percentage shown refers to the oil life, which is a comprehensive calculation based on the vehicle's preset mileage, time, and the distance and duration of driving. This percentage is adjustable, and generally, maintenance is recommended when it falls below around 10%. Normally, maintenance should be performed according to the mileage. Engine oil is a substance enhanced with additives in base oil, primarily containing anti-wear additives, detergents, dispersants, and multi-grade oil viscosity index improvers. Engine oil is used for lubricating internal combustion engines, with its main functions being to reduce friction and wear on moving parts and to remove sludge and varnish from the engine.
