100LL is priced at $2.93, self serve country airport, county run.. so it has
all the county "tax profits" added in.. we have seen as high as $3.65 this
spring.

Taken directly from the EAA website www.eaa.org and then to the autogas
STC page:
In the opinion of EAA, and in the interest of most conservative
operations, the following observations are offered:
a.. If alcohol content is less than 1%, fuel will probably have no effect
on aircraft.
b.. If fuel contains up to 5% alcohol, caution must be exercised. Do not
permit it to remain in tanks or fuel system more than 24 hours, then drain
and refill with alcohol-free fuel, ensuring that no alcohol concentration
remains in fuel lines or sump. Vapor lock may be a problem. DO NOT FLY.
c.. If alcohol content is more than 5%, DO NOT FLY. Drain fuel system,
flush all parts, replace with clean alcohol-free fuel and run up engine
long enough to exchange fuel in carburetor bowl.
So now the question is posed ... if I take some California gasahol (5.3%)
and dilute it down with 100LL to a 5% concentration, it seems that if I
use it within 24 hours, I can continue to use our gasahol. My calculation
says that 50 gallons of gasahol diluted with 5 gallons of LL would meet
the 5% limitation. Hell, I wouldn't object to running 50-50 if it means I
can cut the lead content in half.
Yet in another place on the website, it says that the gasoline can have NO
alcohol. I'm so confused. {;-)
E'splain to me also why you folks in Wisconsin, Iowa, and the rest of the
midwest are getting your 100LL for $2.50 a gallon or so while I'm paying
$3.50 with the refinery just across the central valley.
