Phillips told his hometown paper that he used a conversion from greasecar.com and paid a mechanic at Evergreen Motors in Greenfield, Mass. who "has done more installs than anybody else" to install it after Phillips realized he couldn't do it all himself (On another website, Phillips says the paper misquoted him a little bit, but doesn't say where or how much).
In the summer months, Phillips uses what sounds like pure biodiesel in the starter tank. He uses B50 now that it's colder out and gets 40-45 mpg on whatever fuel he's using. He has a different scale for "petro-miles," though, and says he can get "hundreds of miles per diesel fuel gallon."
