Oil Change Q&A for Your 1991 GMC R2500 Suburban

  • Why check the motor oil level in my GMC R2500 Suburban? Motor oil lubricates important engine parts. If your oil reservoir is low or empty, these components can grind against each other, generate too much heat, and cause your R2500 Suburban’s engine to fail. 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? First off, changing your own oil isn’t as easy as you’d think. You’ll have to figure out how to properly dispose of the oil and buy special tools. 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 R2500 Suburban exhaust smoke grayish 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, blown piston rings, or old cylinder walls.
