When to Change 1991 Jeep Wrangler Engine Oil

Not sure how or where to get your Jeep Wrangler’s oil changed? Get the advice you need at Firestone Complete Auto Care! We are experts in car care — not just tires. We know all about 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.

Jeep recommends having your 1991 Jeep Wrangler’s motor oil changed at regular intervals. Check out mileage and month info for your Wrangler in the above table. Your Wrangler may need an oil change right away if your check engine/oil change light is on, you hear knocking sounds coming from the engine, smell oil inside the car, or notice excess vehicle exhaust. You may also need an oil change more frequently than Jeep recommends if you haul heavy loads, drive in dusty terrain, go off-roading a lot, or drive at low speeds for long distances. In general, being extra-diligent about oil changes won’t damage your Jeep Wrangler. 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.

What Type of Oil Does My Jeep Wrangler Need?

Whether you need high mileage oil, synthetic oil, or conventional oil, you'll find the right 1991 Jeep Wrangler motor oil at Firestone Complete Auto Care. Jeep has recommendations as to whether conventional or synthetic oil is the ideal engine oil for your 1991 Wrangler. 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 your oil change service, an auto technician will change your Wrangler’s oil, replace and recycle your used oil and filter, check all of your other filters, top-off important fluids, and visually inspect the rest of the vehicle. You can drive easy knowing that we strive to do what's best for your vehicle and take into account your driving habits, and the number of miles on your odometer.

1991 Jeep Wrangler Oil Change Q&A

  • Why check the motor oil level in my Jeep Wrangler? Motor oil lubricates important engine parts. If your oil reservoir is low or empty, engine parts can grind together, overheat, and cause your Jeep Wrangler engine to fail. That’s why you’re better off checking your oil levels and investing in routine lube services.
  • Can I change my Jeep Wrangler oil at home? First off, changing your own oil isn’t as easy as you’d think. You’ll have to figure out how to properly dispose of the oil and buy special tools. Getting a professional oil change reduces the risk of something going wrong during the service, but also help your car perform down the road.
  • Why is my Jeep Wrangler spewing blue or gray exhaust smoke? You could have an oil leak and have a case of burning oil. Looks like it’s time for a professional to take a look. The leak could be the result of worn valve seals, damaged piston rings, or worn cylinder walls.
