Here is a source I found mentioned on another site for gas stations selling ethanol free gas.
Supposedly "pure gas" prevents vapor lock because it has a high boiling point... while ethanol gasoline mixtures lower the boiling point causing vapor lock to occur.

Ethanol free gas is more expensive because the Federal Government
subsidizes oil companies for a portion of the ethanol they
are required to put in the gasoline.
However, you lose about 10% gas mileage using ethanol blended
gas so in the end depending on your driving you are
probably breaking even or saving gas using non-eto gas
depending on the price.
In addition, 1950's engines were designed and built to run on
gasoline that not only did not have ethanol (alchohol) in it,
but also contained a percentage of lead. Much discussion
can be found regarding the lubrication properties of the lead
gas in the valve train, et al., but a very real problem with
ethanol gas is that water binds with ethanol so is very difficult
to drain out like regular gas. This means that for a vehicle that
is not driven often leaving ethanol gasoline in the tank, fittings and
carb for long periods of fine will cause much worse corrosion
than non ethanol gas. _________________ Brian

Does anyone use the lead additives? Are they even worth it or do anything useful? I've heard that the lead-like additives available now to replace the lack of leaded gasoline has no benefit.
Finding and buying leaded gasoline for non-pilots is a challenge. _________________ North Shore, MA
