Not sure how or where to get your GMC C1500 Suburban’s oil changed? Turn to Firestone Complete Auto Care! Our expertise goes beyond 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 1999 C1500 Suburban’s oil at regular intervals. Check out mileage and month info for your C1500 Suburban in the above table. No matter the mileage, your C1500 Suburban may need its oil changed ASAP if your check engine light is on, you hear engine knocking, sense an oil smell in the cabin, 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 at low speeds on long distance trips. More frequent oil changes generally won't harm your GMC C1500 Suburban. 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 C1500 Suburban. GMC has most likely outlined either synthetic or conventional as the best oil for 1999 GMC C1500 Suburban vehicles. Motor oil helps lubricate the engine’s moving parts, regulate engine temperature, and prevent harmful substances from accumulating in the engine. In an oil change service, an auto technician will change your C1500 Suburban’s oil, replace and recycle your used oil and oil filter, inspect the rest of your car’s filters, refill vital car 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 preferences, and mileage.
