Ok, I've got the fuel.
Both samples come direct from the wholesaler so haven't been hanging around at an airport. The new sample was delivered on Monday, the old in August 2004. The old sample has been stored in a sealed insulated tank until yesterday when it was pumped into the aircraft so is representitive of what I am burning. The sample was drawn from the gascolator.
It is immediately obvious that the new fuel is a much more intense blue. The old fuel is still blue but with a greenish tint (if you know what I mean??). Both samples are crystal clear (no turbidity). When (if) we get a sunny day I'll see what happens. Till then they stay dark and sealed.
(If its nice on Friday, Peter, you could maybe come over to be an independant scrutineer and then we could fly to Whitewell for lunch)
The picture gives an idea of the difference. Old sample on left.
