Does anyone happen to know whether the Torando Fuel Safer actually works in improving miles per gallon?

It's an effective tool for wasting money - don't bother.

I agree, WASTE OF $$$ ! ! ! If it actually worked as they say it does, don't you think that all auto manufacturers would be all over it to help with marketing a better MPG on there vehicle ..............

Worthless. CR tested it and found it did nothing along with deer whistles. Just removed mine from my F250 Ford truck and put it back in the box. I'll sell it cheap.
