When to Change 1985 GMC K1500 Engine Oil

Need more info about 1985 GMC K1500 oil changes? Get the advice you need at Firestone Complete Auto Care! Our expertise goes beyond tires. Oil and lube services are also our specialties. 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 changing your 1985 K1500’s oil at regular intervals. See mileage and month specifics in the above table. Outside of GMC-recommended oil change intervals, your K1500 may need an oil change if your check engine light is on, you hear knocking sounds coming from the engine, smell oil inside the vehicle, 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, go off-roading a lot, or go at low speeds on long distance trips. More frequent oil changes generally won't harm your GMC K1500. 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 1985 GMC K1500

  • What can low oil do to my GMC K1500 engine? Motor oil lubricates important engine parts. If your oil reservoir is low or empty, engine parts can grind together, generate too much heat, and cause your GMC K1500 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 K1500 oil at home? Changing your own oil isn't as convenient as you might 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 it’ll also help your car perform smoothly down the road.
  • Why is my GMC exhaust smoke gray or blue? There could be an oil leak and your engine is burning oil. It may be time for a pro to take a look. The leak could be the result of worn valve seals, blown piston rings, or worn cylinder walls.
