Not sure how or where to get your GMC C2500 Suburban’s oil changed? Get the advice you need at Firestone Complete Auto Care! We're experts in more than tires. Oil and lube services are also our specialties. After all, "Oil is the blood of the engine. It's the #1 thing you can do for your car," says our maintenance technician, Brianna.

Your 1985 C2500 Suburban’s oil should be changed according to GMC’s recommended oil change intervals. Check the interval for your vehicle mileage in the table above. Outside of GMC-recommended oil change intervals, your C2500 Suburban may need an oil change if your check engine light is on, you hear knocking sounds coming from the engine, sense an oil smell in the cabin, or see an excess amount of 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, enjoy off-roading, or go long distances at low speeds. In general, being extra-diligent about oil changes won’t damage your GMC C2500 Suburban. Each oil change is actually another chance to check and resolve other car issues, such as worn brake pads or tire treads.

Oil Change Q&A for Your 1985 GMC C2500 Suburban

  • Should I check my GMC C2500 Suburban motor oil level? Engine oil lubricates moving parts in your engine. If you're low or out of oil, engine parts can grind together, generate too much heat, and eventually lead to GMC C2500 Suburban engine failure. That’s why it’s best to check your oil levels and get your oil changed regularly.
  • How hard is it to change GMC C2500 Suburban oil at home? First off, changing your own oil isn’t as easy as you’d think. You’ll have to buy special tools and figure out a way to recycle the old oil properly. Having your oil professionally changed reduces the chances of something going wrong with the oil change, but also help your car perform down the road.
  • Why is my GMC exhaust smoke gray or blue? You could have an oil leak and have a case of burning oil. 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, fried piston rings, or damaged cylinder walls.
