With the JK motor from what I have read is that the motor could have been built in one of 2 plants. One in Mexico and the other in the states. Mexico is not the plant of choice. All the information I have read states to run 10W30 synthetic to fix the problem. I have 10W30 full synthetic Mobil 1 in mine and after wheeling, towing a 25 ft. pontoon boat and red light/green light launches the level is steady. I have heard many stories of the dealerships ways to stop oil consumption and would suggest looking into the problem without their help! Come wheeling at the "hangover run" to fix what ales it!
