I've got an 81 900T 8V which has been running almost exclusively for the last three years on a 98 RON 10% ethanol blend in Aus. Note - it is *NOT* happy on 92 RON, ethanol or not! When I got it, the fuel tank was leaking on fillup because all the rubber grommets that the lines pass through had almost completely rotted away. Previous owner had possibly used a local ethanol blend distributor who was experimenting with 18-20% blends at the pump. I dropped the tank and replaced all of those and changed the filter. It's done about 40,000kms over the last three years with no other fuel related attention except for new injectors. They were well on the way to stuffed when I bought it anyway ... The valve seats are hardened in all the turbos so no problems there. Be aware your fuel conusmption will increase a bit, but IME only about 3-4% with 10% Ethanol. If you're running any pre APC engine it won't be very happy with a significant RON drop so watch that if it's appropriate. Higher percentage blends than 10% regularly and 16% occasionally I can't tell you anything about as no experience with them. Cheers
