Looking for anyone who has used this product in either their gas or diesel engines......

Have spoke to a few people who have used it in the RV world and they are telling me they are getting 6-8 MPG better mileage and picking up 15% better horsepower......

I guess this product is a powder and it breaksdown the enzymes and it sticks to the molucules to burn fuel cleaner.....I guess it has been tested by the EPA and has passed all tests.....It is not sold on the shelf...only thru some marketing company.....Looked it up on the net....sounds too good to be true....

Tell me if you have heard of it or have used it.....
