Will E10 or equivilent Fuel hurt my stock 253?

Why can't you use E-85? Higher octane won't hurt an engine. You just don't get any benefit unless you up the compression ratio. Or is there another reason?
The other point to consider, especially in cars that don't get driven regularly is ethanol attracts water. If you leave it sitting for periods the water will seperate from the fuel, research phase separation.
So you can save a dollar, bugger all your hoses, maybe rust out your fuel tank or worse run the separated ethanol through the engine.
Why spend up to 50k doing up a Sandman and then try to save 40 cents on a tank of alternative fuel?

Interesting link wb. Methanol is hygroscopic, logically methanol fuels will draw water to stored tank of fuel, sure, probably, perhaps unfavorably, but water in the tank is a very common thing, anything less than a full to the brim tank of any sort of petrol causes condensation.
Incidently, Diesel is also hygroscopic (just in general discussion of fuel tanks).
Perhaps its a point to consider that maybe E-10 stored in a tank isn't great, (however the regular ULP in my stored kingy with half a tank smells like paint varnish, but she still fires up.) But all fuel tanks gain water, condensation is pretty hard to avoid. I dunno though, if Victoria and NSW are moving to 6% ethanol for ULP anyway theres not much than can be done but to prepare a fuel system for ethanol or pay for the ultra premium (which will still have ethanol it it by the sounds of it anyway). But it's not too drastic, my new opinion (as of talking to Shell this week) is that H series Holdens will drive on what they are fed and owners just need to fix them up as they go along which shouldnt be too bad.

But yeah, probably a good idea to slowly change rubber/composites to E-10/methanol standard if using E-10 (or even ULP) to avoid breakdown situ (such as fuel leak from the seperator box, or rubbergranules in the carby).

Regading E-85 - I dont know, this thread was about E-10. I called Shell, they dont make E-85, perhaps Burmah do?
