Oil Change Q&A for Your 2021 GMC Sierra 2500 HD

  • What can low oil do to my GMC Sierra 2500 HD engine? Engine oil is a lubricant for the moving parts in your engine. If you're low or out of oil, these components can grind against each other, generate excess heat, and cause your Sierra 2500 HD’s engine to fail. That’s why you should check your oil and get it changed regularly.
  • Can I change my GMC Sierra 2500 HD 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 changed professionally can not only reduce the risk of something going wrong during the service, but also with your vehicle down the road.
  • Why is my GMC Sierra 2500 HD spewing blue or gray exhaust smoke? You could have an oil leak and have a case of burning oil. It may be time for a pro to take a look. The leak could be the result of worn valve seals, damaged piston rings, or worn cylinder walls.
  • Where can I get GMC Sierra 2500 HD oil changes? Firestone Complete Auto Care performs GMC Sierra 2500 HD oil changes and more! Our technicians also replace oil filters, troubleshoot oil leaks, and advise on the right oil for your ride.
  • What can cause the oil light on my GMC Sierra 2500 HD to illuminate? If you’re overdue for an oil change, it might trigger your GMC Sierra 2500 HD oil change reminder light. If the oil pressure light is illuminated, it could be due to low engine oil, a failing oil pump, a malfunctioning oil pressure sensor, or a clogged oil filter.
  • Should the oil filter be replaced when getting an oil change for my GMC Sierra 2500 HD? You should replace your GMC Sierra 2500 HD during each oil change. The filter captures debris and contaminants to help keep your oil clean, which means the filter gets dirty. If you skip replacing the filter, you’ll contaminate your new oil with the dirty filter.
