Looking for oil change recommendations for your 1990 GMC C3500? Look no further than Firestone Complete Auto Care! We are experts in car care — not just tires. We know the ins and outs of 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 1990 C3500’s oil should be changed according to GMC’s recommended oil change intervals. See mileage and month specifics in the above table. No matter the mileage, your C3500 may need its oil changed ASAP if your check engine light is on, you hear knock knock knock coming from the engine, 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, go off-roading a lot, or go at low speeds on long distance trips. Generally, getting more frequent oil changes won’t hurt your GMC C3500. 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 1990 GMC C3500 motor oil: either synthetic or conventional. GMC has recommendations as to whether conventional or synthetic oil is the best motor oil for your 1990 C3500. Motor oil reduces friction between engine components, keep the engine cool, and prevent harmful substances from accumulating in the engine. During your oil change service, a technician will change your C3500's oil, replace and recycle your used oil and filter, check all of your other filters, refill vital car fluids, and perform a courtesy inspection on your entire vehicle. You can rest assured knowing that we seek to do what’s best for your C3500 by considering your driving habits, and mileage.
