Looking for oil change recommendations for your 1989 Jeep Comanche? Turn to Firestone Complete Auto Care! We are experts in car care — not just tires. We know all about motor oil, too. After all, like our maintenance technician Brianna says, “Oil is the blood of the engine. It’s the #1 thing you can do for your car.”
Jeep recommends having your 1989 Jeep Comanche’s motor oil changed at regular intervals. Check out mileage and month info for your Comanche in the above table. No matter the mileage, your Comanche may need its oil changed ASAP if your check engine light is on, you hear engine knocking, sense an oil smell in the cabin, or notice excess vehicle exhaust. You might need an oil change more frequently than what’s recommended by Jeep if you regularly haul heavy loads, drive in dusty areas, adventure off-road, or drive at low speeds for long distances. More frequent oil changes generally won't harm your Jeep Comanche. 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 you need high mileage oil, synthetic oil, or conventional oil, you'll find the right 1989 Jeep Comanche motor oil at Firestone Complete Auto Care. Jeep has recommendations as to whether conventional or synthetic oil is the best motor oil for your 1989 Comanche. This oil helps lubricate engine parts, regulate engine temperature, and prevent harmful substances from accumulating in the engine. During your oil change service, one of our techs will change your Comanche’s oil, replace and recycle the old oil and filter, inspect all of your other filters, top-off important fluids, and perform a courtesy inspection on your entire vehicle. You can rest assured knowing that we seek to do what’s best for your Comanche by considering your driving preferences, local climate,
