Yeaterday I gassed up for the first time since May 20, 1021.8 miles. 12.3 gals. The car said 87.6 MPG My calculator said 83.07MPG. That is a 5% diff. I don't trust a calculators results after a one tank average because there are too many variables, such as gas filler length, pressure, temprature, etc. Driving home from the station the temp was 110, no A/C, window down 4 inches, driving very careful the current MPG seamed "stuck" on 150. It stayed that way untill I got into stop and go traffic. When I got home it was down to 130.8 MPG after 16.8 miles. That didn't sound right so I checked the accuracy of my trip A 14194 miles and Trip B 38206 miles. Trip A car = 78.4, calculator =75.96. 3% diff. Trip B car =76.8, calculator =74.095. 3.5% diff.
I get better milage in the heat too. Maybe it's the summer gas and or better atomization.
I don't know how accurate 130.8 is but it's fun to brag about.

An easy way to check if it actually is stuck is simply push on the gas, if the insantaneous milage goes down, it's not stuck.
I have had it really stick at 150 twice before. Nothing I did would move the instantaneous bar. I finally turned the ignition off and back on and that fixed the stuck bar.
The winter gas season is from October through March. When I gased up on April 20, I was hoping that all the winter gas was gone. I got my personal best one tank mileage of 91.1 on that fillup. I think you can count on about a 5% loss on winter gas.
