Need more info about 1989 GMC C1500 oil changes? Look no further than Firestone Complete Auto Care! We're experts in more than tires. We know all about motor oil, too. 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.”
Your 1989 C1500’s oil should be changed according to GMC’s recommended oil change intervals. See mileage and month specifics in the above table. Outside of GMC-recommended oil change intervals, your C1500 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 an unusual amount of 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, go off-roading a lot, or drive at low speeds for long distances. More frequent oil changes generally won't harm your GMC C1500. 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.
Whether it’s synthetic, conventional, or a blend of both — your local Firestone Complete Auto Care has the right oil for your GMC C1500. GMC has most likely outlined either synthetic or conventional as the ideal engine oil for your 1989 C1500. This oil helps lubricate engine parts, keep the engine cool, and prevent harmful substances from accumulating in the engine. In an oil change service, a technician will change your C1500's oil, replace and recycle your used oil and oil filter, inspect all of your other filters, top-off essential fluids, and visually inspect the rest of the vehicle. You can drive with confidence knowing that we look out for you and your C1500 by taking into account your driving habits, and odometer.
