“Gov. Arnold Schwarzenegger tells Outside magazine that he switched one of his gas-swallowing Hummer SUVs from regular diesel to biofuel, and now when he drives it, “It smells like French fries.” ”

here is what Arnold said on that matter in a speech of june 06:

“GOVERNOR: Well, I get driven around by the CHP, so my vehicles are all kind of stored. I still drive my G-Wagon around every so often, or my little Excalibur, which is a little sports car. But no, I don’t drive them that much at all. I maybe drive now five times a year a Hummer, that’s about it.”

cheers,
