Oil Changes for 2003 GMC Sierra 1500

Need more info about 2003 GMC Sierra 1500 oil changes? Look no further than Firestone Complete Auto Care! Our expertise goes beyond tires. We know the ins and outs of 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.”

Your 2003 Sierra 1500’s oil should be changed according to GMC’s recommended oil change intervals. See mileage and month specifics in the above table. Outside of GMC-recommended oil change intervals, your Sierra 1500 may need an oil change if your check engine light is on, you hear engine knocking, 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, drive in dusty areas, adventure off-road, or go at low speeds on long distance trips. In general, being extra-diligent about oil changes won’t damage your GMC Sierra 1500. In fact, every oil change is an opportunity to diagnose and treat any other issues, such as bad brakes or a failing battery.

Whether you need high mileage oil, synthetic oil, or conventional oil, you'll find the right 2003 GMC Sierra 1500 motor oil at Firestone Complete Auto Care. GMC has specifically identified either synthetic or conventional as the best motor oil for your 2003 Sierra 1500. Motor oil helps lubricate the engine’s moving parts, regulate engine temperature, and keep harmful substances from building up inside the engine. During an oil change, a technician will change your Sierra 1500'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 drive with confidence knowing that we look out for you and your Sierra 1500 by taking into account your driving habits, and mileage.
