Not sure how or where to get your GMC C1500’s oil changed? Turn to Firestone Complete Auto Care! We are experts in car care — not just 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.”
GMC recommends changing your 1990 C1500’s oil at regular intervals. See mileage and month specifics in the above table. No matter the mileage, your C1500 may need its oil changed ASAP if your check engine 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 may also need an oil change more frequently than GMC recommends if you haul heavy loads, frequent dusty roads, go off-roading a lot, or go long distances at low speeds. More frequent oil changes generally won't harm your GMC C1500. Each oil change is actually another chance to check and resolve other car issues, such as worn brake pads or tire treads.
Whether you need high mileage oil, synthetic oil, or conventional oil, you'll find the right 1990 GMC C1500 motor oil at Firestone Complete Auto Care. GMC has specifically identified either synthetic or conventional as the best motor oil for your 1990 C1500. This oil helps lubricate engine parts, keep the engine cool, and keep harmful substances from building up inside the engine. In an oil change service, an auto technician will change your C1500’s oil, replace and recycle the old oil and filter, check 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 preferences, and odometer.
