How Often to Get 1986 GMC S15 Oil Changes

Not sure how or where to get your GMC S15’s oil changed? Look no further than Firestone Complete Auto Care! We're experts in more than tires. We know all about motor oil, too. We couldn’t put it better than our technician, Brianna. She likes to explain to customers that, “Oil is the blood of the engine. It’s the #1 thing you can do for your car.”

Your 1986 S15’s oil should be changed according to GMC’s recommended oil change intervals. Check the interval for your vehicle mileage in the table above. Your S15 may need an oil change right away if your check engine/oil change light is on, you hear engine knocking, sense an oil smell in the cabin, or see an excess amount of vehicle exhaust. You might need an oil change more frequently than what’s recommended by GMC if you regularly haul heavy loads, drive in dusty terrain, adventure off-road, or drive at low speeds for long distances. In general, being extra-diligent about oil changes won’t damage 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.
