how will ethanol affect my fuel mileage ?

Just so we can move along.... Because this thread isn't about the MPGs of a Subaru.

It's still a loss of 5+ MPGs which is significant. That would be in the 20+% loss range, along the lines of what others here have mentioned.

It's about real life experiences. Have you had any with it? And that's mostly daily driven car in the city miles with some highway. My car with regular gas is lucky to get 250 with just city. Just depends how well your car is tuned also. 250 one tank highway and city is pretty good if your romp on it.
