|
|
There are a choice of 3 fuels here in Thailand.
'Normal' 95 octane
91 octane
95 Gasohol (ethanol) either E5 or E10
Normally I use normal 95 but many areas of Thailand no longer have it and I have to fuel up with 91 with a higher risk of detonation.
I was advised not to use ethanol because it may not be compatible with the fiberglass fuel tank and also because of high humidity here. I know a friend using ethanol in his Zenair 701 without problems (but that has aluminum tanks) and most cars here run on E10 but I have also heard horror stories about ethanol.
A friend used ethanol on his motorbike and after leaving it standing while he was away for 2 months, the carburetor system was ruined by a hard residue deposited everywhere.
What fuel does everyone else use for the 100 hp and is gasohol / ethanol safe in the Allegro fuel system?
