How doses oxygenated fuel start a fire on an injected car?  There's no carbs for YEARS.
I heard that the big metro areas (and ALL of CA) that can't make their EPA numbers are recovering vapor emitted when filling your car, and that CA for one is legislating vapor pressure down to where it's pretty comparable to 100LL.
Another nugget that goes virtually nowhere ... Jim S.

Finn covered a lot of it in his post, the vaporization in the carb cools it. This is also the cause of carburator ICING. Many carburated engines will boil the fuel in the float bowl as soon as you shut off the engine. Hard starting when hot is a common problem. Straight up vapor lock can happen in carburated engines when running and it isn't pretty. On of the problems with some of the types of oxygenated mogas is a return to vaporlock problems on some engines. The politicians don't want you to know that the change to oxygenated fuel has caused a rash of carb fires in high-output situations. Look at the side of the road if you live near the grapevine in SoCal, you can hardly go two miles without seeing where some poor souls car flamed on and burned. Close to me on hiway 152 in central california it's even worse. FWIW.
