How Long Can You Drive After the Engine Oil Expires?

[OReed]

How long you can drive after the engine oil expires depends on the type of oil used in the vehicle. Generally, engine oil is divided into three types: full synthetic, semi-synthetic, and mineral oil. Typically, full synthetic oil should be replaced every 10,000 kilometers or once a year. Semi-synthetic oil is usually replaced every 7,500 kilometers or every 7-8 months. Mineral oil is generally replaced every 5,000 kilometers or every 6 months. Below is a detailed introduction to engine oil: Overview: The condition of the engine oil not only directly affects the engine's performance but also impacts its lifespan. The working environment of engine oil is extremely harsh, as impurities from gasoline combustion contaminate the oil, causing it to oxidize and degrade over time. Other: Engine oil, also known as engine lubricant, serves multiple functions, including lubrication and friction reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, and shock absorption.
