Cheers

I also run a EH Holden on boost 98 plus ethanol and it runs great, I went through entire fuel system replacing anything that maybe dodgy and to date everything purring like a kitten .

I do recall seeing in the early V6 days where 93 was mentioned as a minimum.The computer prob detunes itself and effects the spark point with 91. Now d

I used to use 91 in brisbane , with no probs at all with the car. With out stati

There will be a difference with the jet, because you don't get 90% humidit

But they are getting those power differences testing engines on the ground! Im not too sure what other variable might change the power output of an engine between SYD and

Jets are more worried about stalling an engine at altitude -because of lack of air, rather than stalling

'Rubber' hasn't been used in fuel systems for decades. Most cars use some variety of neoprene or nitrile or a blend. The later the car the better. Most cars made in the last 10 to 15 years will have no worries about ethanol with their hoses
