just wondering if anyone has used this product and their opinion, gasoline or diesel. i bought a combo pack the other week for my van, it seems the fuel formula cleaned and helped with the mileage but i have not changed the oil yet to try the engine formula. the engine formula makes me a little curious though, it seem awful thin to be used in the oil, it replaces a quart.

and does anyone know if Carol Shelby sponsors it because he owns it or he gets a big kick back or what, seem like a big name to have as your one and only sponsor? just curious, thanks.
