GMC recommends changing your 1999 K2500’s oil at regular intervals. See mileage and month specifics in the above table.

1999 GMC K2500 Oil Change Questions

  • What can low oil do to my GMC K2500 engine? Motor oil lubricates important engine parts. If your oil runs low, these components can grind against each other, generate excess heat, and eventually lead to GMC K2500 engine failure. That’s why it’s best to check your oil levels and get your oil changed regularly.
  • Can I change my GMC K2500 oil at home? Changing engine oil at home isn’t as simple as it’s made out to be. 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 it’ll also help your car perform smoothly down the road.
  • Why is my GMC K2500 spewing blue or gray exhaust smoke? Your engine could be burning oil due to a leak. 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.
