How Often Should You Really Change Your Oil?

If you’ve ever heard someone say “every 3,000 miles,” you’re not alone. That used to be the golden rule—but cars have changed, and so have oil standards.

So how often should you actually change your oil? The answer depends on a few key things:

1. What Kind of Oil You Use
Synthetic oils last longer and handle higher temperatures better than conventional oil. If you're using synthetic, your intervals could stretch to 7,500 to 10,000 miles, depending on your vehicle. Blended oils fall somewhere in the middle. Conventional oil is still fine for some vehicles, but typically needs changing more often.

2. Your Driving Habits
Short trips, stop-and-go traffic, and towing all put more stress on your engine. If that sounds like your daily drive, more frequent oil changes—every 3,000 to 5,000 miles—might still be smart. Frequent idling and cold starts can also speed up oil breakdown.

3. What Your Vehicle’s Manual Says
Every car is a little different. Your owner’s manual gives the best recommendation for your engine and oil type. It’s worth checking—especially if your car has features like oil life monitoring systems.

4. How Old Your Car Is
Older engines can burn oil or have buildup that affects performance. In those cases, it’s safer to stick with shorter intervals. Regular oil changes can help prevent costly repairs and extend the life of an aging vehicle.

5. The Type of Driving You Do
Driving mostly on the highway? Your oil may last longer than you think. Constant highway speeds are easier on your engine than city traffic. But if you’re mostly city driving or live in a hot climate, shorter intervals are a good idea.

Why Oil Changes Matter
Oil keeps your engine running smoothly by reducing friction, preventing overheating, and carrying away debris. Skipping oil changes can lead to bigger (and more expensive) problems—like engine wear or even failure. Clean oil helps maintain fuel efficiency and protects engine parts from grinding and overheating.

It’s one of the most affordable ways to protect your investment.

Can’t Remember Your Last Oil Change?
If you're unsure when you last had it done, it's better to be safe than sorry. Look for signs like dark or dirty oil on the dipstick, loud engine noise, or the oil light coming on.
