Not sure how or where to get your GMC S15’s oil changed? Look no further than Firestone Complete Auto Care! Our expertise goes beyond tires. Oil and lube services are also our specialties. 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 1983 S15’s oil should be changed according to GMC’s recommended oil change intervals. Check out mileage and month info for your S15 in the above table. No matter the mileage, your S15 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, drive in dusty terrain, adventure off-road, or go long distances at low speeds. Generally, getting more frequent oil changes won’t hurt your GMC S15. 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.
Your local Firestone Complete Auto Care has the right 1983 GMC S15 motor oil: either synthetic or conventional. GMC has specifically identified either synthetic or conventional as the best oil for 1983 GMC S15 vehicles. Motor oil reduces friction between engine components, regulate engine temperature, and prevent the build-up of harmful substances within the engine. In an oil change service, a technician will change your S15's oil, replace and recycle the old oil and filter, inspect all of your other filters, refill vital car fluids, and perform a courtesy inspection on your entire vehicle. You can drive with confidence knowing that we look out for you and your S15 by taking into account your driving style, weather and road conditions,
