Train wreck !!!! Train wreck !!! Looks like my original post has gone
off the rails a bit. My PRIMARY CONCERN is what alcohol does / will do
to my fiberglass tanks and any other untested component in my fuel
system. My fuel system, as well as most, is a series system of
components and the failure of any one component is a 100% failure of the
system. Aircraft approved for auto fuel use are approved for "alcohol
free" fuel. I have no way of knowing how the dozens of seals, gaskets,
fuel lines, pumps, shutoff valves, etc. designed for use with my 80 year
old engine technology will react with alcohol and I don't intend to take
it to 5000 feet to test it. I was simply looking for an option, if it
is do-able and convenient, to the price of 100LL with it being a well
proven fuel. I don't want to duplicate what a friend did years ago with
his big Stinson Gullwing when he used the wrong brake fluid and it
caused some "O" rings to swell and locked up his brakes. Fortunately
the issue developed on the ground.
My other concern with auto fuel is when left in the carb for extended
periods the gas evaporates and leaves a highly contaminating gummy brown
crap. Ever wonder why you mower runs like crap the first time in the
spring. I assume it flushes out with fresh fuel but there are times
when the carb needs to be removed and cleaned to work again.
I'll stick with 100LL if I can't find a reliable / cheaper alternative.
