there's only one genuine e85 in aust at the moment and that is made by csr. The rest have oct rating is piss poor and not consistent . Reason why v8 supercars only use csr fuel is its consitent to meet strick race ragulations
E85 is great but at about $2.20 a ltr and burns twice as much per km to normal 98 oct is not a daily fuel to use.
