Martin,
I puzzled about this too. It appears that the CAA in the UK has a
dislike of unleaded fuel. In New Zealand we only have unleaded
and there are a large number of homebuilts (many with 912's) running
quite nicely on unleaded 91 with full authority from our CAA.
We recently had a fuel specialist speak at out local EAA branch and
he said that the most important thing was to watch fuel ageing. Fuel
left in a tank, metal of plastic, loses its volatility (goes stale)
over a while.
I suppose you should check with your
local EAA to see what the regulations are in the USA but I suspect
unleaded will get the go ahead.
