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.
Your 1989 G2500’s oil should be changed according to GMC’s recommended oil change intervals. See mileage and month specifics in the above table. Your G2500 may need an oil change right away if your check engine/oil change light is on, you hear knock knock knock coming from the engine, smell oil inside the car, or notice excess 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 at low speeds on long distance trips. In general, being extra-diligent about oil changes won’t damage your GMC G2500. Each oil change is actually another chance to check and resolve other car issues, such as worn brake pads or tire treads.
Whether you need high mileage oil, synthetic oil, or conventional oil, you'll find the right 1989 GMC G2500 motor oil at Firestone Complete Auto Care. GMC has recommendations as to whether conventional or synthetic oil is the ideal engine oil for your 1989 G2500. This oil helps lubricate engine parts, maintain proper engine temperature, and keep harmful substances from building up inside the engine.
