Just to make sure - I hope you know, that you need few modifications to run E85? Like bigger injectors, uprated fuel pump, remap?

Unless the manufacturer says so it is not safe to run on ethanol mix I think.

I'd say 5-10-15% of ethanol should definitely be no problem, as Subaru uses usually pretty rich mixture (this probably can differ on some already tuned cars), rich enough to deal with additional oxygene from ethanol.

I drive on mix of about 10-15% ethanol everyday without any issues to part solve problem of low octane fuel in Ireland.

NASIOC guys tried even more, up to 30% - but this can make fuel going too lean - going to higher percentage without modification is not suggested.

Anyway - if anyone wants to get more advantage with ethanol mixtures, he/she should think about a remap (definitely needed to run on e85).

I take it E85 = ethanol/85% petrol..?

Is it any cheaper and what are the benefits/octane..?

Its 55p a litre at my local garage in France. Every petrol stataion has it over here. I'd like the STI converted but can't seem to get any sense out of Subaru at the moment. 20% more power and 15% more torque on turbo cars; yes please

85% ethanol 15% petrol

Silly question, what is E85?

Phildodd - you have answer just above
15% petrol, 85% ethanol

Here you have pretty much information and discussion
E85 fuel FAQ - Engine Management & Tuning - NASIOC
Just remember that in US octane number is (ron+mon)/2
