Drove my 2021 fx4 scab to the cabin. 200 miles. Left with full tank and filled up at 174 miles. Computer said 25.2 mpg. My math showed 25.76. This was on 87. Filled up with 91, premium here, for the hill climb. Even then, going from 1200 ft to over 4k in about 10 miles then driving to cabin another 10 got me over 22. Impressed.
