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.
Your local Firestone Complete Auto Care has the right 1985 GMC K1500 motor oil: either synthetic or conventional. GMC has most likely outlined either synthetic or conventional as the best oil for 1985 GMC K1500 vehicles. This oil helps lubricate engine parts, keep the engine cool, and prevent the build-up of harmful substances within the engine. During your oil change service, a technician will change your K1500's oil, replace and recycle the old oil and filter, check all of your other filters, top-off essential fluids, and perform a free inspection on the rest of your vehicle. You can drive easy knowing that we strive to do what's best for your vehicle and take into account your driving habits, and the number of miles on your odometer.
