All the gas in Ontario has had ethanol, usually up to 10%, for some years
now and I have noticed no ill effects the Healey, although it plays hell
with my British bikes. The bikes are relatively high compression and
air-cooled. The Ethanol, (and possibly other additives or changes in
formulation from the 60s) slows the burn rate down. The bikes with domed
pistons and plug set to one side have problems as it takes the flame front
has a long way to go to get something close to complete combustion. As a
result we have to advance ignition as much as possible without inducing
pinging, and lower the CR. Takes a lot to get them running well. But the
Healey - no worries. I am bad and even leave the fuel in it over the winter
and it just starts right up in the spring as it has every one of my 35 years
of ownership.
PS - I hate using additives - one more thing to think about (I am inherently
lazy) and I have some faith in the chemists at the gas companies and do not
want to experiment by adding something else.
cheers,
Mirek
