Actually, until recently Mogas has ALWAYS had high vapor pressure.  Nowadays it is being legislated down (by the EPA) to nearly the level of 100LL.  I see cars along the highway too.  I'm just not prepared to make an unequivocal statement that the cause was carb vapors from high volatility Mogas.  Is it possible that instead of them all being 25-30-year-old carburated cars, they might be poorly maintained 10-year-old cars that ruptured a fuel line?  Are there physical failure modes for injectors? Let's not grab onto the first unsupported generality that comes our way ... Jim S.

Jim, don't know where you're located but I see 20 year old cars, (with carburetors), around here all the time. Not sure if the problem was with vapor issues or corrosiveness of fuels with alcohol.
