Winter is here and with the snow modification season   In Sweden we have a cheaper, more environmental friendly fuel called E85. It is 85% ethanol and 15% petrol.   I used it in my car, currently 2/3 E85 and 1/3 petrol because of starting issue with pure E85 in cold weather. In summertime I tried running on pure E85 with good result.   My car is an BMW 1994 with M50 engine. It has a very adaptive ECU and large dimension fuel pump and injectors. Most other cars needs to raise the fuel
