Oil Change Q&A for Your 1990 GMC R1500 Suburban

  • Should I check my GMC R1500 Suburban motor oil level? Engine oil is a lubricant for the moving parts in your engine. If your oil reservoir is low or empty, engine parts can grind together, generate too much heat, and eventually lead to GMC R1500 Suburban engine failure. That’s why it’s best to check your oil levels and get your oil changed regularly.
  • Can I change my GMC oil on my own? Changing engine oil at home isn’t as simple as it’s made out to be. You’ll have to figure out how to properly dispose of the oil and buy special tools. 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 exhaust smoke gray or blue? There could be an oil leak and your engine is burning oil. It may be time for a pro to take a look. A leak can be caused by a variety of issues including faulty valve seals, damaged piston rings, or damaged cylinder walls.
