Looking for oil change recommendations for your 1989 GMC K3500? Turn to Firestone Complete Auto Care! We are experts in car care — not just tires. We know the ins and outs of motor oil, too. After all, "Oil is the blood of the engine. It's the #1 thing you can do for your car," says our maintenance technician, Brianna.
Your 1989 K3500’s oil should be changed according to GMC’s recommended oil change intervals. Check the interval for your vehicle mileage in the table above. Outside of GMC-recommended oil change intervals, your K3500 may need an oil change if your check engine light is on, you hear engine knocking, 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, drive in dusty terrain, enjoy off-roading, or go at low speeds on long distance trips. More frequent oil changes generally won't harm your GMC K3500. 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 K3500. GMC has most likely outlined either synthetic or conventional as the best motor oil for your 1989 K3500. Motor oil reduces friction between engine components, regulate engine temperature, and keep harmful substances from building up inside the engine. During your oil change service, an auto technician will change your K3500’s oil, replace and recycle your used oil and oil filter, check all of your other filters, top-off essential fluids, and visually inspect the rest of the vehicle. You can drive easy knowing that we strive to do what's best for your vehicle and take into account your driving habits, local climate,
