At the risk of sounding like a hippy i was wondering whether its possible to run bioethanol /E85 in our 2-strokes?

Or does it need weird oils and higher compression to work well? And i heard somewhere it eats rubber bits and needs extra fuel filters etc?!?

Might have an insider in British sugar who makes the stuff...

we've been doing some tests on it at the university although i've not been involved, i understand it's pretty aggresive stuff and you need particular fuel lines and filters - it also dissolved some sealant inside some jerry cans and blocked the Formula Ford fuel filters

not sure how 2 stroke oils will take to it though

i'll ask about what you'd need and wether it's do-able

Take a look at the strand on Carbon Neutral Hovercraft earlier this year. My understanding is that most of our engines can run 10% straight away - don't know about 85%

Years ago I worked for a firm making fuel caps for cars; we had all sorts of trouble with bio dissolving the sealing rings inside the fuel caps!

Aggressive? I'd say so!

But it can be potent- i saw a saab with an engine properly modified for 100% ethanol making 300hp from 2litres...

Hi Peter,

Are you sure that wasn't methanol? Methanol is commonly used as a race fuel as it can run at higher compression than petrol. I think there are bike racing classes that use it.

Whereas the average hippy can tolerate a bit of ethanol, I wouldn't advise giving him methanol.

Just realised its turbocharged but still quite impressive;

And the russians dont seem to mind methanol!
