We run E85 in our mini. Its not a pump fuel though. Its 85% percent elthanol, and smells like methanol. Its 108 octane and burns very slow compared to normal unleaded.
We get 20lt for a carton of coronas from a unnamed workshop, so about 2.25 asd a litre.
Would not work in a std NSR though as you need to advance the timing a fair whack to get the best out of it. It also has a much higher ideal afr, so you need to richen it up ALOT.
Apparently they are releasing a 'pump' version that will called 'E85', except its very gay at about 95RON, and will probably destroy any car tuned on the real 108 stuff in a matter of seconds.
