Most cars can last 5,000 to 7,500 miles before needing an oil change. If your car uses synthetic oil, you may be able to go even longer between oil changes: up to 10,000 to 15,000 miles.
But driving past your oil change due date can potentially cause damage to your engine.
The numbers above are general guidelines, and won’t apply to every make and model—especially if you own an older vehicle. Check your owner’s manual to see when you should change your oil and follow accordingly.
If you notice any of the following warning signs, you may want to think about changing your oil more immediately:
Change in oil color and consistency
Engine emitting knocking noises
Dashboard warning light comes
If you notice any of these, you should probably postpone your out-of-state trip—or try to make an appointment somewhere else to get your oil changed before you go.
