Most conventional oil brands will have a shelf life of about 5 years. Synthetic oil and synthetic blend oil will last about 7-8 years, and maybe even longer. If you cannot find the expiry date, make sure you use up any half-opened or unopened motor oil bottles within 2-5 years of the manufacturing date.
