Hi.
Here in Norway we have E85(15% petrol and 85% bioethanol) at the pumps.
Since the price is quite a bit lower and the octane number is somwhere around 112 i have used this both on my earlier Audi RS2 and the Audi S6 i have now.
50/50 of E85 and petrol has done wonders for a Turbocharged Audi and i know several people using pure E85 on their older non-turbo VAG's without any issue.
Fuel consumption of E85 is said to be 30% higher then for regular petrol.(backside)
Not sure if you have this at the pumps in the UK?
Its also perfect for MOT.... Close to no "polution"
