As of September 1, 2008 all gasoline must have 10% ethanol by Federal
mandate. So I was told by a Mobil distributor. As always, a really well
thought out Federal mandate. At the same time they raise the CAFE standards
they lower the MPG by mandating ethanol. There was also a bill in Congress
to increase the mandated percentage of ethanol. Guess which lobbying group
was pushing that bill?
