Thanks for clearing that up!

We do 1100 mile mountain trips every couple weeks through the winter. No trailer, but a sled deck and two snowmobiles. Truck is a 2022 F-350, 7.3L with 4.30 gears. Average hand calculated mpg is 11.7 (US mpg) and it is always within 0.2 mpg of what is displayed on the truck.

My work vehicle is a 2020 Ford Transit, with the Ecoboost and 10 speed. Eco-mode only helps in city driving by modifying throttle response, and shift points, straight highway not so much.

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.

Awesome Info Man

Another awesome video my friend

As I've seen it explained that it only reduces the aggressiveness of throttle response, I could see how eco mode would help some for block to block city driving, or lots of stop and go on insane clogged freeways if one isn't a gentle driver on the pedal but otherwise from your testing if you normally drive easy and in your case a fairly steady pace, its dead even ( the slight difference you had would be slight driving differences, nothing more or less ). A great test you performed and proves its more of a gimmick to sell vehicles then anything with substance. Hopefully you have a good floor mat so when the egg breaks it doesn't make a huge mess on the carpet 😄

Great video!! I have the same truck-2022 F250-7.3---3.55 gears. I keep my tires a bit harder than normal(72PSI) as I pull an RV on weekends and don't want to air up and down all the time. My daily drive to work is through my small town(2 red lights) and then 4 miles to work outside of town. I'm always on ECO and consistently show 14.1 mpg. On the highway, with ECO on, using cruise, at 70, I consistently show 17.9. I admit I have not used true fill up gallons/mileage as you did. I was shocked that the ECO mode actually showed worse!! Love the truck, and especially how it handles the RV-30' Coachman 259(7000lbs+). Good luck with yours!!!!

If I’m spending the 75 - 80k to get that truck . . and I have the money to do so, mpg’s are of zero concern. BUT THANKS !

I have the 3.5, I do use ECO mode regularly because it does improve .5 mpg to 1 mpg on the average mpg of a tank of gas. I check average by the tank I will average 19-22. I definitely get worse mpg's in the winter. You did mention you can't use cruise control, I find cruise is key to getting the best mpg's and you could use cruise you just don't want to, put in on 55 in a 55 and I'll bet you can use it. When gas hit $5 a gallon I slowed down more or less to the posted speed limits, doing so significantly stretches the gas tank. I rarely get less than 650 miles from a tank and occasionally will get better than 700 miles from a tank. Prior when I typically drove 75 I would average 525 miles per tank. Honestly doing 55 or 65 vs. 75 has minimal impact on when I arrive somewhere, at most I'd have gotten somewhere 5 minutes earlier, I visit the gas station on average once a month since I slowed down a bit.

this is what i mean by great content! reality!!!!

2022 7.3L 3.55 numbers changed at 10k miles Now, highway empty 15-15.5 mpg love this truck.

I have a 3500 cargo van with 6.0. It is always loaded with about 1k# and ladders on top. My average is a consistent 12.4 mpg, that is over 20k miles highway, backroads, and a little bit of city driving.

You are spot on!! Got my 2022 7.3 Godzilla in May 2022 and my mileage is exactly the same not towing. Towing my 10,000 lb boat I get between 8.5 and 9 MPG and with my 5,000 lb travel trailer I get just a little over 10 MPG. I love my truck.

I love this truck! Never going back to deezul !!

7.3 Godzilla 430 gearing I usually get 11.4 to 11.8 a gallon

Very well done

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

Open road in central Florida doesn’t exist anymore. Maybe a better road to test on would be i95 😂 Great vid and proper testing!

'21 6.6L Duramax @70-75mph I avg around 19mpg just hauling some stuff in the bed. Never tried it empty... Towing 25' 6500lb TT, avg around 13mpg up in the Rockies.

My 2022 7.3 4.30 won't get over 13MPG unless it's falling out of the back of a C5 at 40,000 feet

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.

Good review. I get about the same, ‘22F350Plat, 7.3, SRW, crew cab, 3.73 ratio… Btw, I get a message if I’d like to go back to previous mode if that mode wasn’t normal. Eco mode seems to mellow throttle response, to a point. It does seem to slow down acceleration when in cruise control mode. If you’re not doing alot of stops and starts it doesn’t affect my MPG. In the summer I seemed to get 1-2mpg better on the highway…

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.

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.

Great vid, I'm looking to move to one of these trucks soon from my F150. I noticed the bed cover you have, is that the factory Ford one, and if so, which one is it? They seem to offer several different ones. Would you consider a short vid on it, how well it works, locks or doesn't, how it is when it's folded, etc? Can't find much info on that stuff on Ford's site, all they say is it folds

Great video!! I know my 2017 6.2 gasser isn’t great. But I didn’t buy it to save gas, I would’ve bought a Prius for that. I wasn’t expecting great gas mileage but for what the truck is, it isn’t bad. And I just found out that Trans Flow has introduced a replacement tank for gas trucks thats 53 gallons.

Turns out you cant turn a 7' tall, 7000 lb, big bore engine thats shaped like a brick in to a Prius. Even if it says eco haha

I have a 2020 f150 sport with a 2.7. For spring break I took a trip of 1926 miles and she got 22.1 mpg. 32000 miles and no problems at all.

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.

Enjoy your video. I think the Ford 7.3 gas will go over good. That’s not bad for a big block gas. Remember the old Ford 460ci. And the Chevy 454ci. Today I have a 04 Chevy 3500 gas 8.1 / 496ci. with a Allison transmission 4.10 rear gears. 10.5 mpg highway and 9 mpg city unloaded. When pulling a 25ft gooseneck heavy loads 20,000lbs+ 6 mpg. The new Chevy 6.6 gets better fuel mileage and has as much power as the 8.1.

I have a 22 powerstroke, mileage is worse in eco. I believe it's due to the hills, doesn't want to down shift until you press the pedal. Regular mode more suitable for our terrain, has a bit more response, shifts down sooner on hills. Also, there is a way to calibrate the fuel mileage calculator on the truck. I did mine to get closer to actual. Will never be perfect, depending on conditions.

Love the sound of that 7.3! Might be my next truck if my 2013 Ram 2500 diesel ever lets up.

I have a 2022 Dodge diesel, dually, with a 6 speed Aisin transmission, 3.73 rear end. Hauling nothing, my best MPG city is 13.9 MPG. I ordered a truck camper and I'll have to let you know how that comes out. NICE video thanks for posting. YES this is the true way to get your MPG.

I get 13.1-13.4 on Normal mode hand calculated. Best I ever got on 535 mile interstate trip was 15.3. My computer is usually off 1-1.5 mpg.

I've got the 23' 7.3 w/ 3.73 gears. I get very similar mileage to what you do. The best I've gotten on the freeway is 16.8 mpg in eco doing 75 in Texas, calm wind with a few hills. I don't know how some of these other youtubers are doing 18 mpg on the highway unless the wind was behind them both ways.

Good stuff very interesting results wh, I have a 2020 f250 PS I haven't done the math right at the pump yet. Touching base on what you said about when you have your truck in a driving mode and have to reset it in the morning. After my duty sits overnight and I restart it, it will ask if I want to go back in that mode. Does it do that with you as well?

hi handsome at 4:19 did you or have you tried that slow cooked Brisket bowl? that looks yummi.

I know it’s not the case for everyone everywhere. But the 2022 7.3 farm truck we have has gotten 15-16 but that’s strictly 75mph Texas interstate where cruise is set for hours at a time. 100-110 mile round trip every day. Never touched ecomode. The second we have city traffic or idle time, it drops to 13 easily lol

Same here, onboard computer is always optimistic on the mpg

I really enjoyed your video. There is one question I have to ask if you have a factory installed keyless remote start?? I own a 2014 f 250 crew cab short bed 4×4 steel body with a 6.2 with 44,000 miles I only do City driving and the everage mpg is 8.5 to 9.5 around town. The best highway mileage I ever got going from Chicago to South Carolina using 92 non ethanol fuel was 17 mph. And when I'm plowing is 3.7 to 6.0 MPG I always calculate my mpg used when I filled up at the gas station and it was always more gallons than what the computer said I used. Until I talk to a ford technician and he said with remote engine start the computer does not calculate engine run time / fuel consumption until the key is placed in the ignition and turned on. I hope that makes sense. That is a beautiful truck you have godspeed and happy travels

My onboard computer mileage is rarely accurate - almost always off by ~1 mpg or 10-12%. If I am 100% highway driving, the difference is lower. I actually HATE Eco mode - lethargic in city driving and rushed transmission shifting that feels like it stays off the power band. I have seen slightly better Eco mileage but not enough that makes me want to use it over normal. My opinion is that ECO mode would make a difference in in-town driving where you may have a lot of stop and go and varying speeds and the shift/acceleration pattern doesn't bother you. But if your driving pattern has a lot of cruising with CC on, then the difference is not going to be as profound because you are staying in basically the same high gears for extended periods of time - no way to have any differentiation. I think Eco only has an effect for low speed/varied speed city driving.

Thanks I don't see a difference with mines on ECO so since the second week I had it I didn't bother putting it on ECO

It's way more fun to drive in tow mode anyway- the eco green leaf on your dashboard is a water pill.

My average on a 2022 F350 with the 7.3 and 3:73 gears FX4 XLT is between 13-14 most of the time. I drive 70-75 MPH on the highway and have very little in town miles. I drove the truck to Canada last fall for a fishing trip with a weeks worth of gear and supplies and 1 passenger. We ran eco for that entire trip and speeds were slower in Canada but the average mileage I saw over that entire trip was 14.5 -15 MPG. Considering my previous truck was a 2004 Ram with the Cummins and it only got 15-17 MPG on the same trip, I'm satisfied with the economy. An my numbers are based off of hand calculations not the computer.

Yes

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

I have a 2020 with the 7.3 Godzilla. I quit using Eco mode a long time ago because it was apparent that Eco was not so…..well, Eco! I did not buy this beast for gas mileage though….it mainly tows a fifth wheel.

My 2020 ram 3500 high output with a banks programer bank cold air intake intercooler and all the charge tubes and a little better than stock turbo, i can get 20 mpg high way on the econmy tune if i keeo my foot oit of it. When im towing equipment at work on my lower of 2 tow tunes i usually get between 6 and 9 with between 20k and 28k behind me. This is all in the northern ca hills where i live. This is y diesel is alleays best if your towing with your truck. Esspecially if your towing heavy gasoline can never compete

2021 7.3 with 3.73 rear 14-16 is about average. Va,Wv,Pa,NC travels

2009 F150 4.6L, 17.xx MPG

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

2017 F-250 XLT, 6.2L with the 6 speed Trans. Average City/Hwy Combined = 11.7 MPG. Towing our 13k 5th wheel we average 6.8 MPG and that isn't going into the mountains either. Yeah, they are thirsty but if you want to play you gotta pay.

I have the 6.2 gasser, but I'm usually 1 - 1.5 mpg below what the computer says. I have a 2018 w/ 85k miles and I'm only getting 10 mpg with mostly city driving and 13 mpg with lots of hwy driving (75 mph) mixed in. I really hoped for more coming from my '17 F150 3.5EB which I usually got 16-19 mpg.

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

Ok, here is the deal with my F150 2018 Platinum with the 3.5 ecoboost.. Im getting the same readings as you. My actual MPG is worse at the pump than the gage by a little more than 1 MPG. on both tests, Normal and eco. Plus, just like you, I did NOT save fuel in eco. Normal was better fuel mileage in everyday driving than when I'm in eco mode... Plus, I tested start/ stop as well and saw NO improvement as well. So now I just leave my truck in normal mode without the start/ stop, and my mileage is consistent, and it is what it is.... My truck is getting 15 MPG around town and 19 MPG highway. I really don't spend much time doing city driving... Ford has some real problems right now. My recalls are out of control, and quality sucks as well.. The worst is my cell phone connection sometime is works, sometimes it doesn't, and they can't seem to make it work all the time. Brother, thanks for the test 🙏 your numbers are spot on... The Banks Family.

I get better mpg when I use mid grade fuel. About 1.5 mpg better on the highway. 2006 F250 5.4 Triton with 125 k miles on motor. 18 mpg keeping it under 70 mph on relatively flat highway. Even though it cost more it still works out to be saving based on how much further I can go on a trip. I also have a lift gate installed so that’s an extra 500 plus pounds I am always hauling around. City driving mpg is terrible-around 11 to 12 mpg

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.

People, what we have here is an agreement between auto manufacturers and fuel producers. I drive a 2000 F150 extended cab with a 4.6L 2v and get between 15-17 mpg, with 238,000 miles on it. Funny how for 20+ years these vehicles have remained so close in gas mileage.... THINK ABOUT IT!!!!!!!

👌👌

11:03 great video. I got a 22 F350 regular cab 7.3 and I do about 10 miles city driving in about 30 miles highway. I do an 80 mile trip every day and it’s telling me so far I just bought it so still tweaking it but it’s saying 17 on the computer so I’m guessing 16 actual. Keep you posted. She’s only got 1000 miles on her just breaking her in so

I had a GMC 8.1 Allison. Got 14.7 Hwy no cruise. Drove the same trip the next time using cruise. Got 13.3. Cruise even on my 7.3 ps and 6.0ps gets me 8% less miles per gallon. Because cruise only knows one speed. And it will accelerate harder to get back to set speed than you driving. There is also a loss of fuel by idle time at stops and so. About a 5-6% loss to consumption.

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.

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!

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

my 1996 ford f-superduty with 7.5 liter 460 ci gasser gets 9 mpg towing a 6k trailer and hauling 2500 on the flatbed

I have a ‘22 Platinum Tremor with the 7.3 and with premium I’m getting about 14 mpg

Does the truck come equipped with rain and snow mode? I know on my a10 Mustang gt that snow mode gives me an extra 1.5 mpg and smooth as butter shift changes. Would make another good video.

I have a early 1994 7.3 IDI and I get 14 mpg but I still need to change the cover neck, downpipe upgrade the turbo will and upgrade my injectors, and that might change

my 07 f350 6.0 6 speed auto (300+k miles) gets 16 mpg around town . its stock bullet proofed egr intact . no DEF inject , no particle filters emission regs just kill the new trucks .also my 2019 f150 5.0 gets the same 20mpg in normal or eco

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…

And do you have the lowest rear axle ratio available? Just wondering and hopefully you’re using a good zero40 motor oil

Is the truck 4wheel drive? My Jeep Grand Cherokee 4WD gets 13-14 mpg in town with a 3.6 v6. So for your engine it’s not bad. I do get 26-30 mpg highway but city driving it’s bad. Liked the video.

It could be the rear axle ratio, and that you have four-wheel-drive and off-road tires

4.30 or 3.55 gears?? BTW....great real mpg test!!

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

What gear ratio is in your truck, and is that a long bed or standard bed?

It mostly just changes shift points and requires more throttle input for the same acceleration. Eco mode on highway does almost nothin.

55-65 miles per hour, that's almost hyper-mile speed. How bad would it be out west going 75-80 miles per hour?

I think eco mode just dumbs down the gas pedal, where you just have to push the pedal more to get the same acceleration. Like if the 1st 1inch =40% throttle in normal mode then in eco that would be say 25% or something to that sort.

Same thing with my 21 Ram Rebel with etorque. Sticker says19/21 and people claim to get that. I'm usually in the 12/13mpg range

I have a 2021 f350 fx4 with the 7.3L gas and I am getting 13.2 mpg in town and highway combined

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

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!

It's hard to find non ethanol gas, that also makes for shit miles per gallon

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

2006 6.0 Powerstroke Supercrew short bed 2wd (95,000 miles) 16-18mpg city/22mpg Hwy (24 mpg on 350 mile trip mostly Interstate.

The reading on the info center on pretty much every vehicle I have come across reads about 9-10% optimistic compared to hand calculating. This truck's behavior is pretty typical. it is too bad the big diesels are so compromised by their emissions crapola. They are awesome when they aren't in the shop for emissions related issues, and even with the higher cost of diesel, their fuel economy advantage more than makes up for the increased fuel cost, especially when towing. Alas, the way things are, it is probably better to skip the 6.7 diesel and it's increased expense, and use the "savings" to buy more gas for the 7.3. This assumes you don't idle the 7.3 too much (something work trucks tend to do by the way) and the stupid variable oil pressure pump doesn't wipe out the valve train from it's sub 10 PSI at idle oil pressure 😆

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.

What does it get Towing that's the important thing

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

I have same truck best i got was 13.7

2022 7.3 4:30 gears 13.5 mpg

The reality is, if you buy a Superduty with the 7.3 Godzilla you don't give a stuff about the fuel economy and that is fine. I want to buy an 7.3 F250 👍

A 4 day test! Nice😊 how much was highway though? Can’t tell much without that. The truck should give you average speed. My 2010 Chevy 1 ton van with the 4.8l engine gets better than the Ford! - (loaded up at around 9000 lbs.)

This doesn't pertain to the 7.3 gasser, but to truck mpg in general. I have a 2010 Silverado with the 5.3 (just for disclosure) and my commute to work each way is a flat 50 mile 2 lane highway with no traffic. I literally leave my driveway and I am on the road, then have about 1 mile of town driving at the end of the highway before I arrive at work. So it is fair to say, I have no stops and starts along the way. If I run it at 70 mph, I average about 15.5 mpg. If I slow down to 55 mph, I am scratching at 22 mpg. This is calculated at the pump, not using the dash numbers. It has a 25 gallon tank, so if I leave 10 minutes earlier each day for work, I save 6 mpg, or 150 more miles per tank. At $3.50/gallon (here in Phoenix), I saved $5900 in fuel last year. That's a lot of fucking money! $6k buys a lot of guns and whiskey! I know it's hard to discipline yourself to slow down, and obviously it all goes out the window when towing, but we do our wallets a disservice by continuing bad habits. Trust me, i'm no tree hugger... I would just rather have that coin to spend on my motorcycles and ammo. Mr. Salty Trips... would you be willing to try your experiment again, just reduce your speed by 10 mph on your way to work in the morning where you wouldn't be holding up any traffic? I know it may not be possible in the PM. I don't care about ECO or normal, I just want to see the result of an mpg test at lower (yet still reasonable) speed. NONE of the MPG tests on youtube offer anything other than their findings at 70 mph, and I am not that driver but I am interested in the 7.3 gasser. Thanks for your consideration.

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'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

Are you using regular or premium gas??? I am told that premium measurably improves mileage.

What does eco mode do? shut down cylinders?
