Looking for oil change recommendations for your 1985 GMC K3500? Get the advice you need at 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.”
GMC recommends changing your 1985 K3500’s oil at regular intervals. Check the interval for your vehicle mileage in the table above. Outside of GMC-recommended oil change intervals, your K3500 may need an oil change 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 areas, enjoy off-roading, or go long distances at low speeds. Generally, getting more frequent oil changes won’t hurt your GMC K3500. 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 K3500. GMC has specifically identified either synthetic or conventional as the best oil for 1985 GMC K3500 vehicles. Motor oil helps lubricate the engine’s moving parts, maintain proper engine temperature, and prevent the build-up of harmful substances within the engine. During an oil change, an auto technician will change your K3500’s oil, replace and recycle the old oil and filter, check all of your other filters, top-off essential fluids, and visually inspect the rest of the vehicle. You can rest assured knowing that we seek to do what’s best for your K3500 by considering your driving habits, and odometer.
