How Often Should I Change My Oil?

The Quick Answer

For most vehicles, you should change your oil every 3,000 to 5,000 miles if you're using conventional oil. If your car uses synthetic oil, you can usually go 7,500 to 10,000 miles between oil changes.

📌 Always check your owner’s manual for the exact recommendation — different engines have different needs.

Why Oil Changes Matter

Your engine runs on oil — it keeps all the moving parts lubricated and helps prevent overheating. Over time, oil gets dirty and loses its ability to protect your engine. If you go too long without changing it, you risk damaging your engine, which can lead to expensive repairs.

How to Know When It's Time

Here are a few signs that your oil may need changing:

  • The oil change light or check engine light comes on

  • Your oil looks dark and dirty instead of golden brown

  • You hear knocking or louder engine noise

  • You’ve driven a lot of miles since your last oil change

  • You can’t remember the last time you changed it

Driving Habits Matter

If you:

  • Drive in hot climates (like here in Arizona)

  • Do a lot of stop-and-go driving

  • Frequently drive short distances

  • Tow or carry heavy loads

…then you might need to change your oil more often than the average recommendation.
