I fueled up with 89 E0 from Sunoco with my last tank and got 41.5 over 413 miles! What a difference! This tank is 87 E0 and i'll see if the big difference was the ethanol content, or the slightly higher octane. So far (about 150 miles) the DIC is reading 42.3, but I know that it is slightly optimistic.
