Post your Gas Mileage : Calculated

Stopped calculating gas mileage for now, too painful. With winter blend fuel and colder temps my wife's last tank was 34.4mpg. That's 80% in town but still pretty far off the 38+ all summer. Not sure how bad it will get once it actually gets cold here.

Fillup after my trip to Branson in the Maverick Hybrid at Sam's Club. Fuel measured was Shell 87 octane E10.
From Harrison AR to Sedalia MO. Strong tailwind for about 275 miles. After crossing the cold front, we encountered 40 mph headwinds and torrential rain for over an hour. This weather and the fact I used ethanol fuel, no E0 was available, lead to my first sub 40 mpg tank.
434.30 miles / 11.353 gallons = 38.25 MPG
Thinking the weather and ethanol were probably equally guilty in the 5.8 mpg drop from the 44 mpg on the previous tank.

Civic 33.1 Jeep 22.0 Ford F-150 16.2 Corvette 24.0 These are basic observations and the boat wide open gets 4.0 MPG but who cares I am catching walleyes. If you really want to know the average MPG which is really accurate to to FUELLY.COM and you can browse any car or truck that you wish. My Civic gets 36 MPG on the highway very easily driving 81 MPH. The lowly Honda Civic amazes me more than any of my more expensive toys.
 
Filled up today with E0 the tank at 9 DTE . 539.3 gallon / 14.462 gallons = 37.3 MPG
Surprised it was this good after all the cold sub freezing driving on this tank of 87 octane E10 from Sam's Club.

Ecosport (has neither) 533 milea in LTA since last OCI, F.E. going down in the winter to a terrible 24.7mpg around town.

So much for Ford D.I efficiency. but likely due to high vapour pressure, light constituent and low(er) BTU content winter fuel.
I did crank up the tire pressure and it's got fresh oil. I might redirect the factory CAI to the space between the radiator and engine. I noticed that this engine appears to like hot air ingestion to improve F.E.

My wife's Crosstrek has been near 33mpg last month. But that thing revs about 3500 on the highway with the 6MT !
 
Winter is starting to affect my well-worn G5 as well. Average during summer from the dash readout is about 7.1-7.3L/100km; we are now up to 7.8, and further into the winter it will be 8+.
Transmission is showing its age, and hesitates and shifts very roughly when cold. Have to idle for a couple of minutes now just to get it to engage.
