Like the conscientious honesty in your post.

Not trying to be contradictory just for the sake of it but usually the members who claim those really high freeway mileage can’t back it up with fuelly or even a trip computer that shows average speeds above 60mph

We all have different driving styles, routes, & hypermile desires. Even the best, most consciousness, most experienced hypermilers won't set MPH records if the majority of miles driven are freeway miles with nearly all ICE operation. Rural, lightly traveled roads at lower speeds can result in extraordinary MPG numbers, as we all know. My 2025 Lariet AWD Hybrid has 6,029 miles, 2,800 of those have been over the road interstate miles, with a lifetime avg of 34.xx MPG. I'm happy with that number factoring the comfort, convenience of the truck bed, fun driving, & room for 4 passengers. Maverick Rocks!

I see people doubting MPG numbers if they don't come from an app like Fuelly, but it is pretty easy to divide miles driven by gallons consumed. I use a spread sheet to track my actual MPG, and for the last 2 tanks have been recording the displayed MPG to see if the difference between it and actual is consistent enough to warrant re-calibrating of my display.
I tend to drive like @Mavster Mechanic and also use OBDII data to help me decide when to give it some pedal and when to back off and "sail"

I’m doubting claims of highway MPGs in the 40s.

While extra work, your spreadsheet shows the same data as fuelly.

Based on the time between fill ups I’d venture to say most if not all of your driving is not highway.

Only a few miles were NOT highway

Granted this was one of my best which is why there is a photo but 40's is quite typical.

I was not going 75 for long but after having my blinker on for like 30 seconds no one would let me merge so I had to gun it to get in front of them before missing my exit.

Mostly 67 MPH with some city that's 80% EV.

I have been driving hybrids for 20 something years. I understand them well and I know lots of hypermiling techniques. Hell, I used to hang out with the guy who invented the term "hypermiler".

50 MPG at 50 MPH is catchy and easy to remember and is what the Maverick Hybrid is capable of in fair weather.

Slower than that I can get 60 MPG in daily life. Real world conditions.

To me and the government in general, 55 MPH = highway speed.

This is for sure, no doubt, a 40+ MPG truck at modest highway speeds.

(Not so much at Texas and Utah highway speeds, which is obvious. Speed lowers MPG. )

The astute will notice the above trip isn't a particularly slow trip. The timer is key on to key off. There were many stoplights and stop signs. But mostly ~55 MPH highway in the middle.

What contributes to my higher than Average MPG?

I bought the lowest weight, low rolling resistance tires available on tire-rack in the stock size.

I inflate my tires to 40 psi. =

I don't run heat when it's above 55°F.
(but I run the seat heaters often, they use negligible power)

I don't run air conditioning below 85°F.
(but I run with my window partially open all of the time. Wind drag is negligible at 55 mph and below)

Just me in the truck.
No unnecessary weight in the truck.

I experiment and pick routes deliberately yield higher MPG. Usually at a cost of 5 minutes a day. &

I use the recommended oil not something thicker.

I never have below freezing conditions.

Use 20 years of hypermile techniques.
Use EV drive to the maximum extent.
Use EV coach every drive.+
Use Slippery Mode almost every drive.
Use an OBDII reader to display actual hybrid SOC continuously.*

I consider my truck a part time EV because it is. In the city with climate control off, I can drive an hour and my engine runs fewer than 10 minutes.

+ The #1 thing you can do to boost MPG for free.

= The #2 best thing you can do to boost MPG for free.

& The #3 best thing you can do to boost MPG

* The #4 best thing you can do to boost MPG is to know how much power you have in your battery "tank". This knowledge is more powerful than people realize and it's a crime it's not a standard feature. Costs a little to add a battery gauge.

You said my spreadsheet is extra work? I input my miles driven and how much gas I purchased, plus if I feel like it the total cost or price per gallon. How does fuelly require less work?
