1999 GMC C3500 Oil Change Q&A

  • What can low oil do to my GMC C3500 engine? Engine oil is a lubricant for the moving parts in your engine. If your oil reservoir is low or empty, these parts can grind together, overheat, and cause your GMC C3500 engine to fail. That’s why you’re better off checking your oil levels and investing in routine lube services.
  • Can I change my GMC C3500 oil at home? Changing your own oil isn't as convenient as you might think. You’ll have to figure out how to properly dispose of the oil and buy special tools. Getting a professional oil change reduces the risk of something going wrong during the service, 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. Looks like it’s time for a professional to take a look. The leak could be caused by several issues like leaking valve seals, damaged piston rings, or worn cylinder walls.
