Hi All,
this seems to be exercising every ones mind at the moment.
This from my local Popular Flying Assoc local Strut. Probably what you call the local chapter of the EAA.
" Bioethenol which as a replacement for petrol is in the early stages in the UK. Most of it comes from Brazil. 85% bioethanol blend is being pioneered at some supermarkets.
A current Safety Information bulletin from Europe has made it likely that motor gasoline will be supplied with an increasing amount of alcohol. The spec. for motor gas. has always permitted the presence of a small amount of alcohol although generally manufacturers have in fact not done so
The CAA states that the effect of the new fuel can be Increased likelihood of deterioration of rubber parts and some other materials causing malfunction of the fuel system and increased leakage and fire risk
Increases the likelihood of water in the fuel separating out at low temps....increasing carb icing etc.
Test as follows.
Put fuel in a clear tube.
Mark a line on it at the fuel level.
Shake vigourously 10/15 secs and let it settle.
If the meniscus is still on the line the sample is alc. free
If it is higher alc. is present.
Of course all you hands on guys knew all that but it is useful info for dumbo`s like me.
Cheers
Pat
