When to Change 1991 GMC G3500 Engine Oil

Looking for oil change recommendations for your 1991 GMC G3500? Turn to Firestone Complete Auto Care! We're experts in more than tires. We know the ins and outs of motor oil, too. We couldn’t put it better than our technician, Brianna. She likes to explain to customers that, “Oil is the blood of the engine. It’s the #1 thing you can do for your car.”

GMC recommends changing your 1991 G3500’s oil at regular intervals. Check the interval for your vehicle mileage in the table above. Outside of GMC-recommended oil change intervals, your G3500 may need an oil change if your check engine light is on, you hear engine knocking, sense an oil smell in the cabin, or notice excess vehicle exhaust. You may also need an oil change more frequently than GMC recommends if you haul heavy loads, drive in dusty terrain, enjoy off-roading, or go at low speeds on long distance trips. Generally, getting more frequent oil changes won’t hurt your GMC G3500. In fact, every oil change is an opportunity to diagnose and treat any other issues, such as bad brakes or a failing battery.

Oil Change Q&A for Your 1991 GMC G3500

  • Why check the motor oil level in my GMC G3500? Motor oil lubricates important engine parts. If your oil runs low, engine parts can grind together, overheat, and cause your GMC G3500 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 G3500 oil at home? 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. Getting a professional oil change reduces the risk of something going wrong during the service, but also with your vehicle down the road.
  • Why is my GMC exhaust smoke gray or blue? There could be an oil leak and your engine is burning oil. Time to have a qualified technician check things out. A leak can be caused by a variety of issues including faulty valve seals, blown piston rings, or damaged cylinder walls.
