It seems that several people really don't want to hear about AutoRx. Well, I just finished a treatment in my wife's 2003 Mercury Sable. The car does exclusively short trips, rarely gets to operating temperature, and generally keeps a mayo-looking moisture emulsion on the fill cap all winter. It developed a small oil leak right as the warrenty period ended. At 36,000 miles I added AutoRX to the Penzoil Platinum 5W20 that had already been in the beast for 1,000 miles. She ran the PP and RX for 2,000 miles. The leak got worse. At 38,000 miles I changed the oil. For the rinse cycle, I added a concoction of every store brand and "no-name" brand that I could find. The leak then got even worse. I cleand the outside of the engin several times and could not tell where the leak was coming from. It seemed to be the cam seal of one side of the V6, the valve cover gasket of the other side, and some third location that I never identified. She ran the cheapo concoction for 3,000 miles. I then switched back to PP 5W20. At about 1,200 miles, the leak stopped! It has now been another 1,800 miles and the leak has not come back. I am now a big fan of AutoRX. Now I have to start re-sealing the driveway - she doesn't like the oil spot.
For those that remember my earlier exercise with AutoRX and a 1970's model Roto-tiller, well, I have left the AutoRX in with 5W40 Belgium Castrol for two seasons and I can't confirm that it did anything. However, the 'tiller did not leak and had no evidence of a problem. I used AutoRX simply because I wanted to try it and I had an engine that was over 30 years old without a rebuild.
