To make a long story short, I bought an '88 Jeep Wrangler cheap. It was in rough shape with 107,000 miles. The 4 cyl. engine ran loud and rough and oil leaked like a sieve. Gas mileage was poor and it struggled to hit 60 mph on the freeway. I took a chance with ARX this past Spring and followed the instructions carefully. I could hear the results early as the engine became much more quiet. In short time, gas mileage increased and I was able to actually pass vehicles on the highway. There are no more puddles of oil in the driveway. I have used ARX to smooth out my power steering system. Next Spring, I will add ARX to the 5 speed tranny and transfer case. This was the best investment I could have ever made in any automotive product.
Thank you for purchasing Auto-Rx and following the instructions it is a great product and you got the results to prove it. I would also add the maintenance dose to your engine.
