I am adding my experience of keeping my personal mini fleet of high mileage four cylinder small cars and trucks to the many others who have seen the benefits from your product. I have used it in a 92 Nissan pickup, a 96 Nissan pickup (both D21 models), a 96 Sentra GXE, and a 98 Mazda Protege LX (1.5l). All auto tranny's. I started with the crankcase on each one with a dual treatment due to high mileage, moved on to the automatic transmissions, and finished up with the power steering units. The cooler line flush description on the web site was particularly helpful to a novice DIY'er like myself. The most dramatic results were on the 98 Protege transmission which I have owned (and unfortunately neglected the tranny) since new. The Nissans were purchased used. The Protege went almost 190k miles on the tranny with maybe one service. I can't recall for sure. The old fluid was black. After replacing the main seal which was leaking badly, servicing the tranny pan and filter, I started the crankcase and transmission ARX regimen on the Protege. 20,000 miles later the Mazda is still shifting perfectly after the ARX treatment.

 I figured the tranny was toast but I it seems to be fine for now. The other vehicles showed similar improvements in performance and hopefully will offer many more miles of service. I also used ARX as a maintenence dose in the crankcase for all four.  Again, by appearance of the oil, continued cleaning continued. I will continue to use your product on my vehicles as long as they can get down the road. Also, I appreciated the personal service from you when I called about application and ordering questions.

Before I forget, the mowers and tiller also got a dose!
