When to Change 1990 Jeep Wrangler Engine Oil

Looking for oil change recommendations for your 1990 Jeep Wrangler? Get the advice you need at Firestone Complete Auto Care! We are experts in car care — not just tires. We know the ins and outs of 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 1990 Jeep Wrangler’s motor oil changed at regular intervals. Check the interval for your vehicle mileage in the table above. Your Wrangler 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, sense an oil smell in the cabin, or notice an unusual amount of exhaust. You might need an oil change more frequently than what’s recommended by Jeep if you regularly haul heavy loads, frequent dusty roads, adventure off-road, or drive at low speeds for long distances. Generally, getting more frequent oil changes won’t hurt your Jeep Wrangler. Each oil change is actually another chance to check and resolve other car issues, such as worn brake pads or tire treads.

Oil Change Q&A for Your 1990 Jeep Wrangler

  • What can low oil do to my Jeep Wrangler engine? Motor oil lubricates important engine parts. If you're low or out of oil, these components can grind against each other, generate excess heat, and cause your Wrangler’s engine to fail. That’s why it’s best to check your oil levels and get your oil changed regularly.
  • 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 buy special tools and figure out a way to recycle the old oil properly. Having your oil changed professionally can not only reduce the risk of something going wrong during the service, but also with your vehicle 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. Time to have a qualified technician check things out. A leak can be caused by a variety of issues including faulty valve seals, damaged piston rings, or worn cylinder walls.
