1 Answers
Engine oil can still be used after its expiration date. The shelf life of engine oil is as follows: 1. Unopened engine oil has a shelf life of 5 years; 2. The remaining engine oil after maintenance has a shelf life of 1 year; 3. Engine oil poured into the engine has a shelf life of 6 months. Engine oil, also known as engine lubricant, serves to lubricate and reduce friction in the engine, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption. Engine oil consists of base oil and additives. The base oil is the main component of the lubricant, determining its fundamental properties, while additives compensate for and improve any deficiencies in the base oil's performance. It can be categorized into diesel engine oil and gasoline engine oil.
