Does anyone have any information of what the composition of this product is? I was not able to download their data sheets for some reason. They claim no solvents or kerosene carrier, and it claims to do some of the same cleaning as auto-rx would do for a transmission. The only difference that is readily apparent is the Lucas may change the viscosity of the atf where the auto-rx would not. We all know the good benefits of auto-rx, but how would this Lucas product stand against it. They make a fuel system cleaner that I tried that is also eco friendly that claims to improve mileage. On one of my vehicles a 94 ford 351 windsor it did on the other it actually dropped the mileage. That product seems similar to Fuel Power.
