1985 GMC C1500 Suburban Oil Change Q&A

  • Why check the motor oil level in my GMC C1500 Suburban? Engine oil lubricates moving parts in your engine.

  • Can I change my GMC oil on my own? 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 help your car perform down the road.
  • Why is my GMC C1500 Suburban exhaust smoke grayish or blue? There could be an oil leak and your engine is burning oil. Time to have a qualified technician check things out. A leak can be caused by a variety of issues including faulty valve seals, blown piston rings, or damaged cylinder walls.
