Looking for oil change recommendations for your 1990 GMC K3500? Look no further than Firestone Complete Auto Care! We're experts in more than tires. We know all about motor oil, too. After all, "Oil is the blood of the engine. It's the #1 thing you can do for your car," says our maintenance technician, Brianna.
GMC recommends changing your 1990 K3500’s oil at regular intervals. Check the interval for your vehicle mileage in the table above. No matter the mileage, your K3500 may need its oil changed ASAP if your check engine light is on, you hear knocking sounds coming from the engine, smell oil inside the vehicle, or notice excess vehicle exhaust. You might need an oil change more frequently than what’s recommended by GMC if you regularly haul heavy loads, frequent dusty roads, go off-roading a lot, or drive at low speeds for long distances. More frequent oil changes generally won't harm your GMC K3500. In fact, every oil change is an opportunity to diagnose and treat any other issues, such as bad brakes or a failing battery.
Your local Firestone Complete Auto Care has the right 1990 GMC K3500 motor oil: either synthetic or conventional. GMC has recommendations as to whether conventional or synthetic oil is the best oil for 1990 GMC K3500 vehicles. This oil helps lubricate engine parts, keep the engine cool, and prevent harmful substances from accumulating in the engine. During an oil change, a technician will change your K3500's oil, replace and recycle your used oil and oil filter, inspect the rest of your car’s filters, top-off essential fluids, and visually inspect the rest of the vehicle. You can drive easy knowing that we strive to do what's best for your vehicle and take into account your driving habits, weather and road conditions,
