Personally I'm more attracted to SVO systems, but I'd happily use biodiesel or a good tested blend for start/stops in my twin tank Land Rover or in my diesel work truck. If I could get hold of either..... http://www.ncaur.usda.gov/oc/ocfuels.htm this was the other information I was thinking of but it's just more of the same.
