It really depends on your vehicle and the type of oil that was used in your last oil change. Fully synthetic oils can let you drive longer between oil changes (and they’re even required for many vehicles. Our best advice is to check your owner’s manual– most will say around 3,000 to 5,000 miles between oil changes. Stick to that schedule when you first purchase your vehicle. Then ask your mechanic or one of the oil change experts at Express Lube if more frequent oil changes are recommended.
