10,000 Miles or Six Months

Most synthetic motor oils are rated to last as long as 10,000 to 15,000 miles; some even last as long as 25,000 miles, under normal driving conditions. This does not include extreme driving conditions, such as towing, hauling, extreme weather, excessive driving or racing.

3,000 Miles or Three Months

The need to change your oil every 3,000 miles or three months is an old myth and definitely does not apply to synthetic oils. While most synthetic oils last almost three times as long as this, having your oil changed every three months or 3,000 miles is a good preventive method against engine damage, and allows a mechanic to inspect your vehicle frequently.

Bottom Line

The amount you drive will determine your oil change schedule. If you drive frequently under extreme conditions, or rarely drive more than 10 miles, which does not heat the oil enough to boil off moisture condensation, you may need to do it more often; but your owner's manual will advise when to change your oil, based on your vehicle's scheduled maintenance.
