CRAZY RESULTS: F250 7.3 Godzilla MPG Normal vs ECO challenge!

My Nissan Titan is WAY off, says 17 MPG and is really 14 MPG. The software that tracks this stuff is garbage in every vehicle.

Great comparison. I would be interested to see if you use a higher octane. I have a 6.0 Diesel and I decided that tracking mileage vs economy was not worth it. I have another vehicle that offers that "ECO" choice and lets just say it is a bunch of BS. Great video.

You should have just bought the 6.7. I get 18-19 going to work and back. I had a honda accord that had eco mode and it always got worse mileage when using it.

Sorry if this is a dumb question but I just picked up a 2023 F-350 7.3L on Thursday. How do I put it in eco mode? Searched the manual with no luck. Assuming I don’t have the option…

The big beast of a truck what do you expect I love my 2021 F-350 Tremor 7.3 Gas with the 4.30 gears best truck I ever owned

2015 Ram 3500 6.7l Cummins diesel. Tracked every tank of fuel since new with fuelio app. Now over 80k.Fuel economy from 11.2 with a headwind and 7 ft tall cargo trailer to 19.7 empty on two lane road through KS and CO with nearly no stops or taking cruise off. What lowered my mpg was avg speed being lower, longer idle time. Tracked truck avg speed, mpg, idle and drive hours. Truck calculated mpg from.2 to 2.1 higher than actual. Didn't buy it for fuel efficiency.

3300 miles on mine. 7.3 crew cab fx4 package 373 gears I’m at 16 mpg. 78 mile daily commute.

LOL! My 79 Cadillac coupe deVille gets 14mpg in a carderated 7.0L, but really a 4x4, heavy towing capibility, everything that truck can do really isnt that bad at 13.1mpg. How much does the truck weigh? My coupe is at 4600lbs. Anyway, id love to have a f350 godzilla! I love big blocks!

21 7.3 I have a spray rig with 3000lbs in it and average 8.8 mpg . Best empty 11.8 mpg

We just drove to Alabama from Ohio and back with my 2014 6.2 and got a consistent 15.5 to 15.8 mpg ...lie o meter said 14.8 and 15. 3 its off by about .7 mpg

I have a 2011 F250 with 6.2 Gas engine, crew cab, standard bed, amd FX4 on it. Currently my tires are 295/70R17LT Mickey Thompson Baja Boss. Driving around unladen I usually average about 12 mpg.

I don't drive it that much due to my occupation as a OTR trucker. I've had it about 7 years and put maybe 15k miles on it. It's not super fancy or tricked out, pretty much all OEM. Gets the tasks done that I want, had been reliable, and most importantly is paid off.

I wonder what sport mode comes out to!!??

Eco Mode is designed for around town driving, and no faster than 45mph... otherwise youre better in normal. Eco takes fuel away and shifts points are closer.

What does it get Towing that's the important thing

Same here, onboard computer is always optimistic on the mpg

I have 6.2 f250 13mpg

Awesome Info Man

What does eco mode actually do technically? I suspect it only affects the transmission characteristics like the tow mode. Also does the higher octane make any difference? I suspect temperature and humidity make more difference in fuel economy than eco or other modes.

I get 14 MPG in my 2020 7.3

Wow, lower than I expected. I have a 31’ Class C motorhome on a 2023 E450 chassis with the 7.3L. When towing my Jeep Gladiator, I’m getting 8 MPG (calculated). No complaints considering it has the aerodynamics of a rolling brick.

Ford 460 and not much in the MPG sector lol

I have a 22 with 65k miles on it. In all the different ways I drive, I have gotten everything from 10-18mpg.
I'd say the norm for me is 13mpg, that's a normal day of 75mph for an hour, idle for an hour, back and forth between the two with an average of 250-300 miles per day.

Are you sure you didn't hit tow haul mode?

I have a 2022 6.2 with 6 speed trans and getting 10.2 mpg

You must work nights.

Seriously gosh you didn’t marry your wife because she was gonna beat your hook playing your fish or skin the deer debone it and cook it enjoy your truck you knew it wasn’t gonna get 20 miles to the gallon anyway

2004 4x4 V10 Excursion with 3.73 gears gets me about 13.5 doing 65

Another Sham by Ford

I've been wanting to get a used f250 but every time i see my camry getting 40 to 43mpg on freeway going 70mph I'm glad don't have to pay gas for a truck

👌👌

issues oil pumps: pumps were put in on purpose low sourcing $$ cost cheaply made , factory variable pressure oil pump needs to be thrown in trash, put regular aftermarket high pressure pump , lifter failures caused by low oil pressure idle city, heat etc - high duty part need oil High pressure constantly , heart is Oil pump ~ idiots

I think your math is a bit off in the 1st run: 164.5 miles at 12.8 Gal is calculated to be 12.85 mpg (not 13.2 like you're saying). The 2nd run numbers are correct (calculated mpg is 13.1). So bottom line, the ECO mode is a bit better (2%). Nothing to write home about, but at least there's no anomaly. Besides - one may argue that looking for anything "ECO" in the Godzilla is a bit delusional... 😎

I have a 2018 crew cab 8ft bed 6.7L DIESEL I get 22mpg on the Highway 19.6 city.

make sure you have a hard boil egg!!!!!!!!!

01 f350 powerstroke. Four door, 4x4, long box, dually, automatic, 8000lbs, not tuned; running down the highway at 65 I get 14.5 mpg

Density altitude makes a difference in mileage as well. So many variables. Eco mode is a joke

I have a 2022 F 350 supercab cab+chassis srw with a 9 ft svc body, 7.3 gasser ,4.30 rear axle, keep tires at recommended psi, get a bit over 13 mpg hand calc truck calc always bumps it up to 14 mpg, can't rely on these damn computers!

2022 F350 with 4.30 gears, normally around town and hwy 12.7, and hwy around 14 on a good day. I love the power of the engine, transmission 10 speed sometimes feels clunky, but with trailer it’s better. I wanted a manual transmission but Cummins is the only one with that option, but new diesel’s mileage suck, and cost $1.50 per gallon more.

My 2011 f150 5.0 gets 14.4 mpg on average. I have seen 17 mpg on a long road trip. One thing I know for sure is driving to work in the morning I'll have a head wind. Then the wind will change directions and I'll have a head wind on the way home too lol

What rear axle gear ratio does you truck have?

21 6.7 diesel 15-18.4 mpg. 60 gal tank. I can drive from St. Louis to Denver on 3/4 of a tank.

2009 F150 4.6L, 17.xx MPG

So my real godzilla, my 2004 avalanche with the 8.1 vortec and 2.93 gears do 14.2 mpg on the highway, 13.2 wit a 2k pound trailer, andc8.5/9 with the trailercloaded, what is the improvement after all this years? And the avalanche only have 4 speeds! Lol

Anybody know if the new 6.8 mini godzilla gets better mileage than the 7.3? If so how much better?

What does eco mode do? shut down cylinders?

The computer lies all the time!
