1990 GMC G1500 Oil Change Q&A

  • What can low oil do to my GMC G1500 engine? Engine oil is a lubricant for the moving parts in your engine. If you're low or out of oil, engine parts can grind together, overheat, and eventually lead to GMC G1500 engine failure. That’s why it’s best to check your oil levels and get your oil changed regularly.
  • Can I change my GMC G1500 oil at home? Changing engine oil at home isn’t as simple as it’s made out to be. You’ll have to buy special tools and figure out a way to recycle the old oil properly. Having your oil changed professionally can not only reduce the risk of something going wrong during the service, but also help your car perform down the road.
  • Why is my GMC G1500 spewing blue or gray exhaust smoke? There could be an oil leak and your engine is burning oil. Time to have a qualified technician check things out. The leak could be caused by several issues like leaking valve seals, blown piston rings, or worn cylinder walls.
