1999 GMC C2500 Oil Change Questions

  • Should I check my GMC C2500 motor oil level? Engine oil lubricates moving parts in your engine. If your oil runs low, these components can grind against each other, generate too much heat, and eventually lead to GMC C2500 engine failure. That’s why you’re better off checking your oil levels and investing in routine lube services.
  • Can I change my GMC oil on my own? First off, changing your own oil isn’t as easy as you’d think. It requires special tools and old oil must be disposed of properly. Having your oil changed professionally can not only reduce the risk of something going wrong during the service, but it’ll also help your car perform smoothly down the road.
  • Why is my GMC exhaust smoke gray or blue? Your engine could be burning oil due to a leak. 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 damaged cylinder walls.
