~2000 miles round trip to Canada in 2012 Honda Fit with 5 people and fully loaded gear maxing out weight limit. Break down is below:
1) first leg of 600 miles averaging 35.5 mpg. Vehicle is rated for 33 mpg and likely with one occupant and no gear. Tire pressure was 38 psi instead of 32 psi due to increased load. On flat surface, fuel economy was 40 mpg but that dropped to 35.5 once terrain became mountainous and long stretch of up hill requiring high rpm and downhill required slight down shift to maintain speed limit. There were also long stretch of 25 mph, 35 mph, and 45 mph through town.
2) City driving omce in Canada for almost 800 miles brought overall fuel economy to 32 mpg. Ontario roads were bad with pot holes and plenty of traffic lights. Middle leg only had 4 occupants instead of 5 and very minimal gears instead of fully packed.
3) Moderately pack gear and 3 occupants on return trip of 600 miles raised overall fuel economy to 33.5 mpg and my calculation is that the return leg itself averaged at 39 mpg when I drove and about 30 mpg when a new driver drove for 100 miles through hilly terrain with posted speed limit of 70 mph.
All three legs had A/C blasting due to the need to close the vent as the route taken was through industrial mountain towns with a lot of factories pitting out high sulfur and other pollutants.
During mid trip inspection, engine air filter was clean because in air intake picked up a piece of plastic bag covering over half of the filter. The cabin air filter was gunk up after 400 miles of mountainous terrain passing through coal mines and factories regions.
A better vehicle for this trip would be a hybrid or something with a turbo but the Fit held its own.

This is normal for ALL LOCAL driving.
Months with highway driving get me 26-28mpg with scattered months topping 29mpg.

Today MAZDA CX5 NA 2.5L. 25.2mpg calculated and agrees with the dash reading by 2% so not more calculating for my MAZDA CX5.

4600 miles Az to Pa and back running 75-80 as much as possible in a lightly loaded Sierra HD with the 6.6 gas engine 15.9 mpg overall calculated. 2 mpg difference going and coming back into the wind.
2022 Hyundai Accent. 357 miles, 8.595 gallons ($28.27) 41.5mpg. This tank started off with 200 miles of highway runs followed by a bunch of short trips. If i had filled up when i got back from the trip i would guess 45mpg would have been a realistic possibility.
First report on my new-to-me '79 Deville, and it's actually not too bad:
273/19=14.37 MPG. Smack in the middle of its EPA rating of 12 city, 18 highway. No AC usage, 25/75 city and highway with speeds kept to 65 and below.
I filled up with E0 87 octane this go, with an 8.2:1 compression ratio there's no need for anything higher. Given the way she sucks fuel and my love of cruising, I shall report back shortly

Filled up the Maverick at Phillips 66 - 87 octane TT E10. 510.8 miles/ 12.743 gallons = 40.08 MPG
The reported tank was for E0. Did all kinds of driving. It was running a couple of mpg higher during the fill, then the uber hot weather set in for a week or so and the air was full bore most of the time on short trips. Glad I put premium in for that tank, as the Maverick really performed nice in the hot weather.

'Just went on a short Highway trip. Put in 20 gallons of 87. Had 2.5 gallons of E85 in there. Averaged 80 mph on the way there and hit 92 mph at times. Traffic was rolling.. Came back early in the morning averaging 75 mph.. Air Conditioning on both ways.
18 mpg exactly.
