I don't have a scanguage so I can't check the temp. Sorry. it would be nice if it ran a little hotter for the winter tho. I was talking to a guy at Pearsonfuels, the main alternative fuel station in San Diego/SoCal and he said that all Cali stations use at least 5.75% ethanol and will all use E10 by 2009. Pearsonfuels is a cool place, it has basically everything except hydrogen. www.pearsonfuels.com
