Owners of other Jeep, Dodge, Mitsubishi or Chrysler vehicles with the PowerTech 3.7 liter EKG engine such as the Grand Cherokee, Commander, Nitro, Ram 1500, Dakota, Durango, M80 and Raider may also find these oil change instructions to be helpful.

The items needed to complete this procedure include a floor jack, jack stands, a 13mm socket, a ratcheting wrench, a used oil catch container, an automotive funnel, 5 U.S. quarts of new SAE 5W-20 oil, and a new oil filter.

A few compatible aftermarket oil filters include the following with their part numbers: Purolator PL22500, Mobil1 M1-212, Fram PH10575, Motorcraft FL500S, K&N HP-2011, ACDelco PF63, Wix 57045, Pennzoil PZ-173, Mann ML 1049, Royal Purple 20-500 and Bosch 3502.

Next open the hood, twist off the oil filler cap and pull up the oil dipstick. Doing these steps will help prevent a vacuum from forming and allow the old oil to drain out quickly.

Then chock the rear wheels and engage the emergency parking brake to keep the vehicle from moving.

Raise the front of the vehicle with the floor jack and securely support it with at least two jack stands.

Slide underneath the vehicle and locate the black metal oil pan with the 13mm oil drain bolt facing towards the rear. The cylindrical oil filter is located next to the oil pan.

Be careful since the old oil may be hot enough to burn your skin depending on how long you warmed up the engine.

Allow the old oil to drain out for at least a few minutes or until it slows to an occasional drip.

Re-insert the oil drain bolt and tighten it to just past hand tight or about 20-25 ft lbs of torque.

Twist off the old oil filter counter clockwise and allow the oil to drain from the receptacle.

If you have trouble removing the old oil filter, use an oil filter wrench such as the Lisle 63600.

I recommend buying the Mobil1 M1-212 oil filter since it has excellent reviews on Amazon.

Dip your pinky finger into some new 5W-20 oil and lubricate the rubber o-ring on the new oil filter. Lubricating the rubber o-ring on the new oil filter will help it form a better seal, prevent leaks and make it easier to remove at the next oil change.

Do not over tighten the oil filter or use an oil filter wrench to tighten it.

Over tightening the oil filter may damage and cause an oil leak to develop.

Double check that both the oil drain bolt and new oil filter are tight before moving on to the next steps.

Lower the vehicle from the jack stands and floor jack.

Carefully pour in about 4 to 4.5 quarts of the engine's 5 quart total oil capacity.

Replace the oil filler cap, run the engine for a minute, turn it off, and allow it to rest for a few minutes.

Pull out the yellow handled engine oil dipstick and check the level. The oil level should be near the top of the cross hatched area marked with the word "SAFE". If the level is below the crosshatched area on the dipstick, slowly add in a bit more oil and re-check the dipstick. Replace the oil filler cap before running the engine.

You may not need to use the entire 5 U.S. quarts of new SAE 5W-20 oil depending on how long you allowed the old oil to drain out.

Do not over fill the engine since this may damage gaskets or seals and cause oil leaks to develop.

Don't forget to record the mileage and oil change details in your SUV's service record book.
