Theres lots of ethanol free gas in Ontario.  Lucky for me I have one within walking distance.

Great list Sinker, thanks. I see only a couple of stations offer 93 octane, Esso. The rest are all 91 a small few are less. One is down the road in Port Dover, I use that station because it's easy to pull the boat into. I always thought Esso and Shell had higher than 93, guess that might have been in the distant past when I had British sports cars.  67' MGB, 72' TR-6 and a 77'  2+2 E type Jag. None ran well on regular, especially when they introduced lead free.

What is aviation fuel?

aviation gas sometimes also know as race gas is gas used in an airplane that still has lead in it. It is illegal to use on road . Most times it has an octane rating  over 100 which is good in the high performance high compression motors.  It will destroy a catalytic  converter and in modern day motors damage them due to the lead and the confusion they cause in the computers.  It is different than JP5 which is also an aviation gas but is a kerosene based closer to diesel than petroleum.
