Your 2021 Sierra 3500 HD’s oil should be changed according to GMC’s recommended oil change intervals. Check the interval for your vehicle mileage in the table above.

Generally, getting more frequent oil changes won’t hurt your GMC Sierra 3500 HD. In fact, more frequent oil changes give our technicians more opportunities to catch and alert you to any issues, like worn brake pads or a weak battery.

2021 GMC Sierra 3500 HD Oil Change Questions

  • Should I check my GMC Sierra 3500 HD motor oil level? Motor oil lubricates important engine parts. If your oil reservoir is low or empty, engine parts can grind together, overheat, and cause your Sierra 3500 HD’s engine to fail. That’s why it’s best to check your oil levels and get your oil changed regularly.
  • Can I change my GMC Sierra 3500 HD oil at home? Changing engine oil at home isn’t as simple as it’s made out to be. It requires special tools and old oil must be disposed of 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 Sierra 3500 HD spewing blue or gray exhaust smoke? 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 damaged cylinder walls.
  • Who offers GMC Sierra 3500 HD oil changes? You can count on Firestone Complete Auto Care for your GMC Sierra 3500 HD oil change, oil filter replacement, oil leak diagnostics, and more! Our expert technicians will even advise the right oil for your vehicle.
  • What does it mean if my GMC Sierra 3500 HD oil light comes on? Your GMC Sierra 3500 HD oil change reminder light may come on if you're overdue for an oil change. The oil pressure light will typically come on if the oil level in the engine is too low, the oil pump is failing, you have a clogged oil filter, or there's a faulty oil pressure sensor.
  • Do I need to replace my Sierra 3500 HD’s oil filter when changing my oil? It's recommended that you replace your GMC Sierra 3500 HD oil filter with every oil change. Otherwise, you send fresh, clean motor oil through a dirty filter. That's like putting on muddy socks after a shower.
