Looking for oil change recommendations for your 1999 GMC K3500? Get the advice you need at Firestone Complete Auto Care! We're experts in more than tires.

GMC recommends changing your 1999 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 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 go long distances at low speeds. 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.
