Can I go longer between oil changes with synthetic?

Drago-0900@alien.topB to Mechanic Advice@gearhead.townEnglish · 10 months ago

Tldr: The title lol.

I have a 99 Chevy s10 2.2, and it has been running synthetic blend oils (5w-30). It is at 112k miles. And since I am doing my own oil changes, I noticed that blends and full are damn near the same price.

I have been doing 5k intervals with blend, should I go to a 7.5k interval with a full? My truck has a highway maintance schedule in the manual that says it could do 7.5k going by highway miles. I drive mostly highway (speed limit near me goes to 45 at the lowest).

Longer interval with full synthetic is fine on a gasoline engine.

Typically I would do an oil sample with the longer interval to make sure you actuslly have the oil life to go that long with your specific driving conditions.
