I have two Cherokee's with the 4.0 in them. I was quite pleased with my results as well. I followed the procedure oil change and added the Auto-RX. I wasn't expecting any miracles but if it slowed my still slow leak I would have been happy.

I replaced the rear seal on an older Jeep and I can say it was a pain!!! Anyways, my wife and I had to take our daughter from Grand Junction , CO to Salt Lake , UT for a visit to the Shriners Hospital . I was amazed at what my Jeeps overhead console was telling me. Even in this hilly area my Jeep was showing 22MPG?!! In a lifted Jeep with 31's that's not right... I double checked it with my calculator, same thing.

I was averaging maybe 17MPG before ARX which any Jeep owner will tell you is nothing to sneeze at! As of right now no leak whatsoever too. I am starting the treatment on my other Cherokee which is all stock. I'm hoping for the same results if not better!

I'm not sure what to think...being promised something and getting better that expected. That's just not normal. = )
