How long is the shelf life of car engine oil generally?
1 Answers
The shelf life of engine oil depends on its state. If the engine oil is unopened, its shelf life can be up to 5 years; the remaining oil after car maintenance has a shelf life of one year; and the oil poured into the engine has a shelf life of 6 months. Engine oil replacement cycle: 1. Full synthetic oil: Full synthetic oil currently offers the best lubrication and protection performance and the longest service life. For vehicles using full synthetic oil, the replacement cycle can be up to 10,000 kilometers or once a year. 2. Semi-synthetic oil: Semi-synthetic oil can be considered a perfect transition from mineral oil to full synthetic oil, with performance very close to full synthetic oil. For vehicles using semi-synthetic oil, the recommended replacement cycle is 7,500 kilometers or every 8 months. 3. Mineral oil: As the most basic type of engine oil, mineral oil should be replaced every 5,000 kilometers or every 6 months.
