1986 GMC C2500 Oil Change Questions

  • Should I check my GMC C2500 motor oil level? Engine oil is a lubricant for the moving parts in your engine. If your oil reservoir is low or empty, engine parts can grind together, generate too much heat, and cause your C2500’s engine to fail. That’s why you should check your oil and get it changed regularly.
  • Can I change my GMC C2500 oil at home? Changing your own oil isn't as convenient as you might think. You’ll have to figure out how to properly dispose of the oil and buy special tools. Having your oil changed professionally can not only reduce the risk of something going wrong during the service, but also help your car perform down the road.
  • Why is my GMC C2500 exhaust smoke grayish or blue? Your engine could be burning oil due to a leak. Looks like it’s time for a professional to take a look. A leak can be caused by a variety of issues including faulty valve seals, damaged piston rings, or old cylinder walls.
