Just got a flyer from the local distributor of of the US product "Fitch Fuel Catalyst", and I was wondering if any-one has any experience/knowledge of the stuff? Its supose to increase fuel economy of a SBC by 11% or so, and also increases octane levels. Any-one used it or know of it?
Sounds like the same claims made for Acetone. (see link) http://peswiki.com/index.php/Directory:Acetone_as_a_Fuel_Additive
You actually believe this works! Do you think a fuel filter will give you a 11% increase in fuel ecomony?
