How Often to Get 1998 GMC C2500 Oil Changes

Looking for oil change recommendations for your 1998 GMC C2500? 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. 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 1998 C2500’s oil at regular intervals. Check out mileage and month info for your C2500 in the above table. Outside of GMC-recommended oil change intervals, your C2500 may need an oil change if your check engine light is on, you hear knocking sounds coming from the engine, smell oil inside the car, or see an excess amount of vehicle exhaust. You may also need an oil change more frequently than GMC recommends if you haul heavy loads, frequent dusty roads, go off-roading a lot, or drive at low speeds for long distances. More frequent oil changes generally won't harm your GMC C2500. 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.

Oil Change Q&A for Your 1998 GMC C2500

  • Should I check my GMC C2500 motor oil level? Engine oil lubricates moving parts in your engine. If your oil reservoir is low or empty, engine parts can grind together, overheat, and cause your C2500’s engine to fail. That’s why you’re better off checking your oil levels and investing in routine lube services.
  • How hard is it to change GMC C2500 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. Having your oil professionally changed reduces the chances of something going wrong with the oil change, but also with your vehicle down the road.
  • Why is my GMC C2500 exhaust smoke grayish or blue? There could be an oil leak and your engine is 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, damaged piston rings, or damaged cylinder walls.
