Looking for oil change recommendations for your 1989 GMC K1500? Look no further than 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 1989 K1500’s oil at regular intervals. Check out mileage and month info for your K1500 in the above table. Your K1500 may need an oil change right away if your check engine/oil change light is on, you hear engine knocking, sense an oil smell in the cabin, 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 areas, enjoy off-roading, or go at low speeds on long distance trips. Generally, getting more frequent oil changes won’t hurt your GMC K1500. In fact, every oil change is an opportunity to diagnose and treat any other issues, such as bad brakes or a failing battery.
Whether it’s synthetic, conventional, or a blend of both — your local Firestone Complete Auto Care has the right oil for your GMC K1500. GMC has recommendations as to whether conventional or synthetic oil is the best oil for 1989 GMC K1500 vehicles. Motor oil helps lubricate the engine’s moving parts, maintain proper engine temperature, and keep harmful substances from building up inside the engine. During an oil change, an auto technician will change your K1500’s oil, replace and recycle your used oil and oil filter, check all of your other filters, top-off important fluids, and perform a free inspection on the rest of your vehicle. You can rest assured knowing that we seek to do what’s best for your K1500 by considering your driving style, and the number of miles on your odometer.
