Same engine and transmission, different computer settings and different chassis.

I found a non-ethanol station nearby so I fuel there. Every time I go home to NY state, which is mostly E10, my mileage drops 2-3 mpg.
Gas is only 2.25 for regular here. (e10) Gas (100%) is 2.59, doesn't really make sense.
