How Long Can You Go Between Synthetic Oil Changes?

Synthetic Oil Change Intervals

• Synthetic oil lasts about 6 months to 1 year or 7,500-10,000 miles before needing replacement. Most automakers have oil-change intervals at 7,500 or even 10,000 miles and 6 or 12 months. Even if you drive fewer yearly miles, you should still change the oil twice a year.
• Most synthetic oils last 10,000 to 15,000 miles, or six months to a year before needing replacement.
• Synthetic oils typically still look good after 8,000 miles and last up to 6 months (or even 8 months).

Mixing and Compatibility

• You can safely mix one brand of oil with a different brand or conventional oil with synthetic oil.

Considerations for Synthetic Oil Changes

• Most modern vehicles range from 7,500 to 10,000 miles between changes. However, you should still change oil twice a year, even with limited mileage.
• Simply put, manufacturers recommend changing gasoline engine oil every 10,000 to 15,000 km, or about once a year for regular usage or once every two years if used less frequently.
• The longer oil changes are put off, engine problems arise. Most commonly, engines become too hot, causing less efficiency.
