Looking for oil change recommendations for your 1989 GMC G1500? Turn to Firestone Complete Auto Care! We're experts in more than tires. We know all about 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.”
Your 1989 G1500’s oil should be changed according to GMC’s recommended oil change intervals. Check out mileage and month info for your G1500 in the above table. Your G1500 may need an oil change right away if your check engine/oil change light is on, you hear knock knock knock coming from the engine, smell oil inside the vehicle, 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. More frequent oil changes generally won't harm your GMC G1500. Each oil change is actually another chance to check and resolve other car issues, such as worn brake pads or tire treads.
Whether it’s synthetic, conventional, or a blend of both — your local Firestone Complete Auto Care has the right oil for your GMC G1500. GMC has specifically identified either synthetic or conventional as the best oil for 1989 GMC G1500 vehicles. Motor oil reduces friction between engine components, keep the engine cool, and prevent harmful substances from accumulating in the engine.
