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.”
GMC recommends changing your 1986 C2500 Suburban’s oil at regular intervals. Check out mileage and month info for your C2500 Suburban in the above table. No matter the mileage, your C2500 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, drive in dusty terrain, go off-roading a lot, or drive at low speeds for long distances. More frequent oil changes generally won't harm your GMC C2500 Suburban. 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.
Whether it’s synthetic, conventional, or a blend of both — your local Firestone Complete Auto Care has the right oil for your GMC C2500 Suburban. GMC has recommendations as to whether conventional or synthetic oil is the ideal engine oil for your 1986 C2500 Suburban. Motor oil helps lubricate the engine’s moving parts, maintain proper engine temperature, and keep harmful substances from building up inside the engine. During your oil change service, a technician will change your C2500 Suburban's oil, replace and recycle the old oil and filter, inspect all of your other filters, top-off important fluids, and visually inspect the rest of the vehicle. You can drive with confidence knowing that we look out for you and your C2500 Suburban by taking into account your driving style, and the number of miles on your odometer.
