Not sure how or where to get your GMC G1500’s oil changed? Turn to Firestone Complete Auto Care! We're experts in more than 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 1988 G1500’s oil at regular intervals. See mileage and month specifics in the above table. No matter the mileage, your G1500 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, enjoy off-roading, or drive at low speeds for long distances. More frequent oil changes generally won't harm your GMC G1500. In fact, more frequent oil changes give our technicians more opportunities to catch and alert you to any issues, like worn brake pads or a weak battery.
