What is E85? Havn't heard of it over here.
We just have Avgas readily available locally. We can buy it off the pump at gas stations if you can produce a competition license but it is only between 100-104 octane because it is the old gas from the airfields. Me & my mates go straight out to the airfield and get it directly from the underground tanks; we have a BP card so we can use the pump which fuels the smaller airplanes & it is 110 octane minimum.
We arent supposed to use it on the street but heaps of people do.
