Oil Change Q&A for Your 1985 GMC K2500 Suburban

  • Why check the motor oil level in my GMC K2500 Suburban? Engine oil is a lubricant for the moving parts in your engine. If you're low or out of oil, these components can grind against each other, generate excess heat, and cause your GMC K2500 Suburban engine to fail. That’s why you should check your oil and get it changed regularly.
  • How hard is it to change GMC K2500 Suburban oil at home? Changing your own oil isn't as convenient as you might think. You’ll have to buy special tools and figure out a way to recycle the old oil properly. 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 K2500 Suburban spewing blue or gray exhaust smoke? 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 the result of worn valve seals, damaged piston rings, or old cylinder walls.
