paul ,

the latest is maxol are selling E5 which is an enhanced 95 ron.its a blend of regulaer and an ethanol base/byproduct from dairy production.

95% 95 ron
5% ethanol

this equates to about 99.7 ron which is what your tesco and ultimite bp is as far as i know.
eu rules are all petrol must get to this mixture (or more) BY 2012 I THINK.

funny thing is in in Cork down south which is about 40 miles from carbery which produces the ethanol and maxol dont supply e5 to the south
