Oil Change Q&A for Your 1991 GMC K2500

  • Should I check my GMC K2500 motor oil level? Motor oil lubricates important engine parts. If you're low or out of oil, these parts can grind together, generate too much heat, and eventually lead to GMC K2500 engine failure. That’s why you’re better off checking your oil levels and investing in routine lube services.
  • How hard is it to change GMC K2500 oil at home? First off, changing your own oil isn’t as easy as you’d 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 it’ll also help your car perform smoothly down the road.
  • Why is my GMC K2500 exhaust smoke grayish or blue? You could have an oil leak and have a case of burning oil. Time to have a qualified technician check things out. The leak could be caused by several issues like leaking valve seals, blown piston rings, or old cylinder walls.
