When to Change 2003 Jeep Wrangler Engine Oil

Need more info about 2003 Jeep Wrangler 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.

Jeep recommends having your 2003 Jeep Wrangler’s motor oil changed at regular intervals. See mileage and month specifics in the above table. Your Wrangler may need an oil change right away if your check engine/oil change light is on, you hear engine knocking, 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, drive in dusty areas, enjoy off-roading, or go long distances at low speeds. In general, being extra-diligent about oil changes won’t damage 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.

What Kind of Oil Should I Get for My Jeep Wrangler?

Whether it’s synthetic, conventional, or a blend of both — your local Firestone Complete Auto Care has the right oil for your Jeep Wrangler. Jeep has most likely outlined either synthetic or conventional as the ideal engine oil for your 2003 Wrangler. Motor oil reduces friction between engine components, maintain proper engine temperature, and prevent harmful substances from accumulating in the engine. In an oil change service, one of our techs will change your Wrangler’s oil, replace and recycle your used oil and oil filter, inspect the rest of your car’s filters, top-off essential fluids, and visually inspect the rest of the vehicle. You can drive with confidence knowing that we look out for you and your Wrangler by taking into account your driving style, and mileage.

Oil Change Q&A for Your 2003 Jeep Wrangler

  • Should I check my Jeep Wrangler motor oil level? Engine oil is a lubricant for the moving parts in your engine. If your oil runs low, these parts can grind together, generate too much heat, and cause your Wrangler’s engine to fail. That’s why you should check your oil and get it changed regularly.
  • Can I change my Jeep oil on my own? Changing your own oil isn't as convenient as you might think. It requires special tools and old oil must be disposed of properly. Having your oil professionally changed reduces the chances of something going wrong with the oil change, but also help your car perform down the road.
  • Why is my Jeep exhaust smoke gray or blue? Your engine could be burning oil due to a leak. Looks like it’s time for a professional to take a look. The leak could be caused by several issues like leaking valve seals, fried piston rings, or old cylinder walls.
