How Often Should You Change Synthetic Blend Motor Oil?

Regular oil changes will keep your vehicle running like new, and prevent engine failure.

10,000 Miles or Six Months

Synthetic oils are rated to last in an engine from 10,000 to 15,000 miles, or six months. Some synthetic oils last as long as 25,000 miles, or one year. These oils are rated under "normal" driving conditions, and don't include severe driving, extreme weather or towing and hauling.

3,000 Miles or Three Months

Changing your oil every three months is a myth, and does not usually apply to most synthetic oils, even under extreme driving conditions. However, having your oil changed every three months is a good way to have your mechanic overview your vehicle's engine for other problems, and ensures adequate oil levels and usage.

Bottom Line

Your driving methods are the main determining factor in when you need to change your oil. It is always good to change your oil before its rated mileage, however. Consult your vehicle's owner's manual for your car's regular scheduled oil change times.
