pwr2tow yes i believe that is the one i have to find the bottle i looked at it and read it but cant for the life of me remember if it was the premium or not. as i said i think it is yes.
as for mpg ill give you the strait story and let you decide. in a word yes it did. now the deal is this the tank before the fuel additive was driven rather conservitivly, some smoke, some hard accel. i got 13. 5 or so the next tank with soy shield happened to be driven hard high speed driving heavy accel and lots of smoke i saw 14. 3 or 4 about a mpg increase. now the next tank did not have any more soy shield added but was all highway to the tulare farm show and back had easy throttle and steady constant speed with a head wind only one way i got a little over 15. did it work yes i think it did but i dont think it was a good test to judge it on as it wasnt driven the same with and without
