How often should I change conventional oil?

Most manufacturers recommend every 3,000 to 5,000 miles for conventional motor oil, or roughly every 3 to 6 months depending on driving conditions. Check your owner's manual for the exact recommendation for your vehicle.

How often should I change full synthetic oil?

Full synthetic oil typically lasts 7,500 to 15,000 miles between changes. Many modern vehicles with synthetic oil can go 10,000 miles or more. Severe driving conditions (towing, extreme temps, short trips) may shorten the interval.

What counts as severe driving conditions?

Severe conditions include frequent short trips under 5 miles, towing or hauling heavy loads, driving in extreme heat or cold, dusty environments, and a lot of stop-and-go traffic. Under these conditions, shorten your interval by 20–30%.

Can I switch from conventional to synthetic oil?

Yes. Modern synthetic and conventional oils are compatible, and switching is safe at any point. After switching, apply the longer synthetic interval going forward.

Is the estimated date accurate?

The date estimate is based on your average daily mileage. If your driving habits change seasonally, treat the date as an approximation and rely primarily on the mileage target.
