Not sure how or where to get your GMC G2500’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. 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 1991 G2500’s oil at regular intervals. See mileage and month specifics in the above table. Outside of GMC-recommended oil change intervals, your G2500 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, frequent dusty roads, go off-roading a lot, or drive at low speeds for long distances. In general, being extra-diligent about oil changes won’t damage your GMC G2500. Each oil change is actually another chance to check and resolve other car issues, such as worn brake pads or tire treads.
Your local Firestone Complete Auto Care has the right 1991 GMC G2500 motor oil: either synthetic or conventional. GMC has most likely outlined either synthetic or conventional as the ideal engine oil for your 1991 G2500. Motor oil reduces friction between engine components, maintain proper engine temperature, and prevent harmful substances from accumulating in the engine. In an oil change service, one of our techs will change your G2500’s oil, replace and recycle the old oil and filter, check all of your other filters, refill vital car fluids, and visually inspect the rest of the vehicle. You can rest assured knowing that we seek to do what’s best for your G2500 by considering your driving preferences, and mileage.
