14 base FR-S, just over 1 year now.
16k miles

Just took it on an 600 mile trip, getting 1mpg or better driving to work now. Just put 1/2 a tank of real petrol, no ethanol, in on the trip. Seems to have made a difference as I'm getting 27.5 driving to and fro work now.

Any insights. Cleaner fuel system from all petrol super? Not sure, no other changes otherwise.
