1990 GMC G3500 Oil Change Q&A

  • Why check the motor oil level in my GMC G3500? Motor oil lubricates important engine parts. If you're low or out of oil, these parts can grind together, generate excess heat, and eventually lead to GMC G3500 engine failure. That’s why you should check your oil and get it changed regularly.
  • Can I change my GMC G3500 oil at home? Changing engine oil at home isn’t as simple as it’s made out to be. It requires special tools and old oil must be disposed of properly. Having your oil professionally changed reduces the chances of something going wrong with the oil change, but it’ll also help your car perform smoothly down the road.
  • Why is my GMC exhaust smoke gray or blue? Your engine could be burning oil due to a leak. Time to have a qualified technician check things out. The leak could be the result of worn valve seals, damaged piston rings, or old cylinder walls.
