1990 GMC R3500 Oil Change Questions

  • What can low oil do to my GMC R3500 engine? Engine oil is a lubricant for the moving parts in your engine. If your oil runs low, these components can grind against each other, overheat, and cause your R3500’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 R3500 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. Having your oil professionally changed reduces the chances of something going wrong with the oil change, but also with your vehicle down the road.
  • Why is my GMC R3500 spewing blue or gray exhaust smoke? There could be an oil leak and your engine is burning oil. 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.
