How Often to Change 1999 GMC Sierra 2500 Oil

Not sure how or where to get your GMC Sierra 2500’s oil changed? Get the advice you need at Firestone Complete Auto Care! We are experts in car care — not just tires. We know the ins and outs of motor oil, too. After all, like our maintenance technician Brianna says, “Oil is the blood of the engine. It’s the #1 thing you can do for your car.”

GMC recommends having your 1999 GMC Sierra 2500’s motor oil changed at regular intervals. Check the interval for your vehicle mileage in the table above. Outside of GMC-recommended oil change intervals, your Sierra 2500 may need an oil change if your check engine light is on, you hear knock knock knock coming from the engine, smell oil inside the vehicle, or notice excess vehicle exhaust. You might need an oil change more frequently than what’s recommended by GMC if you regularly haul heavy loads, drive in dusty terrain, adventure off-road, or go long distances at low speeds. In general, being extra-diligent about oil changes won’t damage your GMC Sierra 2500. 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.

1999 GMC Sierra 2500 Oil Change Questions

  • Why check the motor oil level in my GMC Sierra 2500? Motor oil lubricates important engine parts. If your oil runs low, these parts can grind together, generate too much heat, and cause your Sierra 2500’s engine to fail. That’s why you’re better off checking your oil levels and investing in routine lube services.
  • Can I change my GMC Sierra 2500 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 spewing blue or gray exhaust smoke? 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, fried piston rings, or damaged cylinder walls.
  • Who can change the oil on my GMC Sierra 2500? Firestone Complete Auto Care is here to care for your vehicle with our GMC Sierra 2500 oil changes and more. Our expert technicians will also suggest the best oil for your vehicle, address oil leaks, and swap out your oil filter.
  • Why is my GMC Sierra 2500 oil light illuminated? The oil change light in your GMC Sierra 2500 could be triggered by an overdue oil change. However, if the oil pressure light is on, you may be dealing with low engine oil, a failing oil pump, a clogged oil filter, or a malfunctioning oil pressure sensor.
  • Does my Sierra 2500's oil filter need to be changed during my oil change? It’s highly advised you replace the oil filter in your GMC Sierra 2500 every time you change the oil. After all, what’s the point of changing our oil if you’re just going to send fresh, clean engine oil through an already dirty filter?
