Need more info about 1991 GMC Safari oil changes? Turn to Firestone Complete Auto Care! Our expertise goes beyond tires. We know the ins and outs of 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.
Your 1991 Safari’s oil should be changed according to GMC’s recommended oil change intervals. Check the interval for your vehicle mileage in the table above. Your Safari 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 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, enjoy off-roading, or go long distances at low speeds. In general, being extra-diligent about oil changes won’t damage your GMC Safari. 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.

You can rest assured knowing that we seek to do what’s best for your Safari by considering your driving style, local climate,
