Ford F-250 Tremor Fuel Economy Test - How Thirsty is the 7.3L Godzilla V8? 

As a service advisor, I would tell folks to go with a gas option every time unless they are towing super heavy and often. Modern diesels are not only significantly more expensive to get into, they are significantly more expensive to maintain, and repair. They also have more maintenance requirements associated with their inherent complex emissions systems, and have more instances of component failures. If a turbo grenades, or a fuel system gets contaminated with high pressure pump guts, it's $12,000-$18,000 to repair. These are also long repairs that exceed 30 flag hours to complete, so even -if- the parts are available, it will be most of a week to repair and test, plus programming, as most of these components integrate with the PCM on a serial basis and aren't plug and play. Meanwhile, you may spend $1200 on a tune up at 100,000 miles for the 7.3. The average oil change is also only $80 on the 7.3L vs $180 for the Powerstroke, and that doesn't include the extra $200-$300 for fuel filter replacement every other oil change, nor the cost of DEF. Even if Diesel fuel cost the same as gasoline, you would never recoup the additional costs, even if you drove it a million miles (which you won't, as those massive repair bills usually cause folks to buy new $80,000 trucks). So again, if you are buying one of these trucks, and especially a single rear wheel unit, 90% should buy the gas option. Your fiscal self will thank you.

Changing the oil in the 7.3 is literally one of the easiest quickest oil changes I’ve ever down.

My 2023 f250 tremor, the fuel economy is 16L/100km at highway. 18-19L/100km at city. It is very comfortable and drive smoothly.

I turn off lane keep assist also. My wife’s suburban damn near crashed one day. There was a construction zone up the road and when I entered it the car was following the lines not seeing the construction obstacles and when I went to follow the cones it was trying to jerk me into the wall and it took serious input to override it.

NICE. Pretty decent Milage for a BIG BOY.

It’s funny how we argue gas vs diesel, payload and towing today. When I was growing up in the 80’s & 90’s, my dad drove trucks from the 70’s. Half ton Silverado, 3/4 ton ford camper special, plus others, same heavy caveman camper went into the bed, same boat was pulled behind it. Those underpowered gas V-8’s just went. No matter how much was loaded into it! I don’t even know if there was a sticker saying how much payload or towing they could handle!! Of course gas was under a buck a gallon, so we didn’t care about mpg.

My new Gladiator Willys has none of the nanny bells and whistles and I LOVE IT! My Cherokee was constantly beeping and hitting the brakes in reverse for no reason. Every time the Cherokee did a nanny thing I had to look around in the menu to turn it off

Hi Steve, I turn the drive Nannys off too. Lane keep assist is a pain, but I do keep the blind side monitoring on.

Thank you! I wish they would publish MPG even if it is not required!

17 mpg on mixed roads -- not too bad. My F150 gets ~23mpg when I say around 60 on rural highways. Just ordered a F250/Tremor/Lariat/Godzilla so hoping I can do the same..... Great video. Thx.

I also keep mine off, while in the right lane the system wants to steer the truck to the off ramp so I have to fight it to stay on the road. It works ok if your not in the lane closest to the off ramps. Left and middle lane driving is ok but I still keep it off.

I have a 2024 Tundra, I prefer to drive it myself, but the lane keep is pretty good!

Picked one up and drove from KC to NC, averaged 13.8 mpg going mostly 68-75 mph. The 7.3's are rarer than the diesel and rarer yet in a Tremor Lariat. I made full use of the adaptive cruise control with lane centering and recv'd the hand on steering wheel warning many times, but not enough for me not to use it.

One of the first things I do in any car is shut it off. Was in a friends Kia a couple of weeks ago, and that car defaulted to on every time he started it.

My Toyota has lane keep assist, works pretty good in daylight in good weather, usually turn it off when the lines are hard to see. I can take my hands of the wheel for 10 seconds before I get a warning, overall I like the system, use it as much as possible.

About the same mpg as my 2000 Ford Excursion with a V10. Granted I’m not running 35’s, but it’s paid for.

Almost 75k miles on my Carli 3" level F250 w 37's. We love this 7.3 with 3:55 gears and get just about the same or slightly better than what you got. Im thinking the gearing is a trade off for the tires. I also changed my running boards, front valance and wheel lip molding from a Tremor. I also have dual exhaust and a 5star tune that I mainly keep in the 87 octane daily drive/light tow tune. 2025 I will get the same truck. Been extremely reliable and she pulls my skid steer and 17k boat.

Steve this is my dream truck and I love it wouldn’t change anything

I prefer to drive without the lane assist. However. I LOVE ghe cruise Control option that stays with the flow of traffic. I have less than 2000 miles and I love this truck

I have to disagree with on the 4.30 not helping fuel economy. You get more torque multiplication, so less load on the engine for the same acceleration and with the 10 speed and big tires, the rpm is still low enough that taller gearing won't make much difference. Plus. As you load it up, it will still feel strong and relaxed and see more of a difference in fuel economy.

I have a 22 f350 Godzilla, I drive a lot, so it already has over 50k miles. great truck, I get around 15 city and 16 highway. Guys out there looking to buy a truck, listen to me. Unless you're towing over 20k everyday, you do NOT, I repeat NOT need a diesel. No way in hell you can justify paying 13K extra upfront for the diesel option and then all the problems you will have from the emission system and paying more for fuel and paying more for services. I owned diesels all my life, trust me, I love diesels, the problem is Modern. diesiels are not what we grew up knowing and loving. The epa has ruined them foreever. it breaks my heart when I see people with a high out put diesel towing 4k pounds and all they have to tow. it's like going off roading with an M1 Abrams tank, so much power and nothing to do with it. Pick any of the big three gas engines (7.3 Godzilla)(6.4 hemi) or (6.6 from GMC/Chevy) any of these three Will do 99% of the towing out there with a lot less upfront and a lot less on maintenance and far more reliable than modern diesels.

While HDs are not rated for MPG/literPer100, they should be. Does not mean the EPA should over regulate, but more info for the consumer is better than nothing. And nothing is what we get with HD class trucks.

I factory ordered a 2021 platinum f350 7.3 with the tow package, while towing my bumper tow toy hauler loaded up (11, 000 lbs) I couldn’t get over 6 mpg! The transmission failed at 16,000miles and with no replacement available at the time my ford dealer bought it back to my relief.

🔥 Loving the channel

With respect to the extra weight of the diesel, I just put a 2.5" lift with new (Falcon) shocks on my 2022 Super Duty (not Tremor) Powerstroke. What you accurately describe when off-roading is much less noticeable now.

Great video TK! How is the visibility up front? Does hood height limit close visibility compared to other HD trucks?

I normally have lane keep assist on when on long drives. It helps keep the drive smoother. But on short drives around town normally it's not used.

Could you do a video towing a travel trailer for the mpg loop? Also, I always turn off the lane assist feature.

My tundra doesn’t have lane keep, but my 2024 Kia carnival does. I only received the hands on wheel message once. I use it often in conjunction with adaptive cruise control.

Gas vs diesel. The choice for me used to be obvious, not so much anymore. Thanks for giving more comparison info!

Awesome review 👍 This is the only Ford that is worthwhile to buy. Not Ecoboost, not Hybrid and not EV. True massive gasoline engine which will last decades or close to a lifetime. A gem…Toyota!!! Bring back V8s if not you are going to lose market share. 14 litres per 100 kms…amazing gas mileage.

Excellent episode as always!!! 😁

I have a 2024 XLT super cab shortbed with the 7.3 gas engine. I drive 65-70 mph and I’m averaging 15.4 mpg so far in the first 4000 miles of owning it. The 10 speed transmission in 10th at 65 mph is only 1500 rpm. So it’s barely above idle. I have the 3.73 ratio rear end.

Hey! I love your videos. Have you ever noticed the infamous Superduty lean? I have a brand new 2024 f350 tremor and noticed it leans to the drivers side. Any ideas how to fix it? Thanks!

I’ve got a tremor with the 7.3 as well, 2020 though and average around 13.5mpg. While the mpg in the 7.3 will always be lower than that of the 6:7, what people fail to talk about is cost/mile. I think doing that and factoring in the extra $10k for the 6.7, it’s VERY hard to justify the diesel.

I always shut off lane keep assist as well unless I am tired.

That's really impressive. My old 08 GMC pretty much gets that for fuel mileage and its 2000lbs lighter, on 33's with 3.73's and has less power overall. Crazy that they can get that out of a lifted 3/4 ton 4wd truck. Used to be that you were lucky to get 24l/100km or 10mpg with something like that.

Not bad numbers for a gas HD with 35’s! My 2017 Colorado ZR2 with the gas engine had similar numbers, and couldn’t do the towing and hauling that this truck can!

Hey Steve do you use the super cruise ? In the GM products

Good and interesting content

2024 F250 Lariat with 7.3, 18" wheels, and 3.73 rear end. I average 14.2 mpg commuting 35 miles to and from Houston Tx, and 8.2 mpg when towing a 5800 lb travel trailer cross country.

How are you pulling those MPGs?! I have a 24 250 Platinum Tremor and I'm lucky if I'm hitting 12.5 mpg with eco mode and highway/back road driving.

A 4.30 axle in the Tremor is not too far off. Standard Tire is 275/65R18 with 3.73 axles. Take a axle ratio calculator for the larger tire of 285/75R18 and it comes to a ratio of 4.07 is needed to be equivalent. I would take it if I was towing with that truck.

Not far off from what my 2024 xlt non tremor 7.3 with 3.73 gets….. I think I get about 14.5-15.5 mpg in the same scenario…. I only tow heavy 6-8 times a year with a total of 1500-2000 miles…. So diesel was not needed in my case. Great video.

I turn off the lane keep also. I'm betting that you won't be able to shut it off in the near future. More regulations coming down the pipe mandating crap like that.

I can pick how much assistance i want but just leave it off most of the time. Sometimes i use it on long interstate runs but thats about it.

I have a 23 F250 King Ranch. Fuel economy in town is about 13 MPG in town. Up to 17 MPG on highway avg. 75 Mph. I don’t use the lane system often.

Regular or premium gas?

I don't have constant reminders with my Ram or Mercedes lane keep assist. My GMC is probably the least intrusive lane keep assist.

It gets similar gas mileage to my stock 2021 Tundra lol. It's really good for a 7.3L but the power also seems low for the displacement?

Lane keep assist and radar cruise got turned off on the way home from the dealership.

Hi Steve , i don't like the drive assist in any of my trucks.

I have the Lariat without the Tremor which gets 14+ local suburban driving on the highway from NY to TN I get better than 17 not too bad believe Diesel doesn’t get a whole lot better.

I love crossovers barrie lmao!

Pretty low fuel consumption for a such big truck. Thanks for review it for us. Greetings

I like the color! Although it would be far nicer with flat black trim everywhere. I thought this far into the 21st century we'd be done with the Chrome thing!

Lane keep assist is exactly that. It isn't autonomous driving. It's meant to keep you in the lanes if you happen to get distracted. It's not blue Cruze or super cruise

How is it off-road? Currently have a Gen 1 6.2 V8 Raptor and I'm looking to upgrade to a 2024 Gen 3 Raptor or go for an F250 as I'll be towing a Bruder trailer and hauling a couple KTM 300s in the back as I overland all over north and central america

My nephew had a 2022 F-250 Tremor gas , he loved the truck right up to the time he sold it, it was a pig on gas, he bought a Tundra TRD PRO with I MAX hybrid engine 437 HP, powerful truck , he’s getting 17-18 mpg average, FOR REAL, and it’s quicker than the Ford

I get 21 US mpg from Sudbury to Timmins with my 4.8 V8 4x4

Better than other HDs I owned in the past. There should be, with all the science and tech, a way to get more MPGs. We are so smart, right?

I can tell you the answer. I have a 24 tremor lariat 7.3. Best I’ve seen on eco mode on the hi-way is 13mpg. Normal non towing average is 11.5. Average on a tank including hauling a 14k lb dump trailer around was 10mpg. Not bad for what I need. I replaced a ram 1500 that was giving me 15-16mpg and could never do what the 250 tremor can.

That’s not bad for a heavy duty truck i have a ram 1500 with a level kit on it and 35” tires and I 14 to 15 on it

My question is if you have lane keep or various forms of pre collision braking, if you turn these systems off as many do, will you be in trouble with insurance in case of accident?? If they check if these system were turned off could they essentially void your coverage? They could say they are there for safety and your not covered for turning them off?

14mpg, about the same as what my 88 F250 with the 460 V8 would get, with less than 1/2 the gears LOL. They're work trucks, they're built to haul and tow not to be fuel efficient LOL. I get around 14-15mpg with my 99 F250 with the V10 out on the highway, but around 10-11mpg in town LOL. So...my 87 Ford Ranger is my daily driver, it gets around 19-20mpg in town and 22-24mpg highway. That 4.30 gear ratio is great for towing, not so great for cruising though LOL. My 88 F250 if I remember right has the 4.10 or 4.30 gears too...my 99 F250 has the 3.73 gears.

That truck gets much better MPG than a Tacoma I saw on another channel with a special throttle controller to save fuel.

14.2 MPG is the best my 2022 7.3 Lariat Tremor got and averages around 12.4 smile’s per gallon.

My old F150 RC with a 6 cylinder/5spd only gets 14mpg on the highway....And i can only tow around 6k pounds

My 2024 3500 L5P with lane departure warning is good. It makes the seat vibrate on the side I'm getting too close to. No pop-up on the dashboard or windshield. Super Cruise is included in the High Country package according to the sales person. I declined. Gas mileage. My 2015 LML six-speed auto with a tune would get 2-3 MPG better fuel mileage than this L5P ten-speed. I'm surprised!

I actually really like these trucks as a Toyota fan. Toyota doesn’t make them so it’s no biggie haha . I like the 7.3 and the GM 6.6 although it’s less powerful. I briefly entertained the thought of getting one in the future just simply for the heavier duty frame payload and towing capacity over my 5.7 Tundra. ….but after really looking it over I don’t tow above 8-10k and it really makes me realize how solid the old second gen tundras are . Even outdated it still makes 401ft lb at 3600 rpm which is around 400 rpm less than the 7.3s 475ft lb I believe . And I get around 16 mpg in the summer . Real world more guys than not , I’m seeing 11-13mpg with a few exceptions here and there on the 7.3. I still like them , but this is my 2nd 5.7 Tundra and if you know how to tow they are beasts . 5000lb +…simply tow/haul S5. Under 5000 S5

Lower rear end ratio would definitely improve things.

My 2018 tundra is just barely above that.

What was the payload on this truck?

I HATE that "Keep your hands on the wheel" part of mine.

1500 Denali Ultimate was annoying too. I turned it off a month ago.

I find that average mpg amazing for such a large heavy duty truck, I owned a 2000 Nissan 3.3 V6 manual 4x4 crew cab that got about 17mpg no matter what kind of tire or driving style. Kudos to Ford and the other truck manufacturers for building some amazing vehicles. Great video TK👍

My f250 with 6.8 in economy mode at 61 mph I can get 18 mpg and at 71 mph I get 16mpg going from ga to Nc

That is exactly the same fuel mileage as my father in laws 6 liter gas GMC HD plain Jane pickup.

I shut off the lane keep assistance for the most part.

I don't use lane keep or blue cruise on my F150 95% of the time; it nags me worse than my wife! 😂

Hell my 2006 150 5.4 3.55 axle never got more than 15 average

Better gas mileage than I am currently getting with my tundra! 🤷🏽‍♂️🤦🏽‍♂️

4.30 rear axle ratio....

Mazda is so configurable. In terms of lane keep and such.

I don't think in the HD sector that the fuel figure is too significant compared to range. How far can it go with a heavy load or towing. I don't think that there are many HD owners who buy these trucks to cruise around empty. Irrespective of trim levels and luxuries, they are work trucks. Put the HDs to work and talk about range!

I would have thought it would do better that. 6.8L V10 with 3.73 gears is about the same mpg. Im sure your truck is alot nicer though.

It’s better than my buddies 2024 tundra with no life or anything special and stock tires. They are dura tracs but stock size.

What is the point of that engine? Barely more HP and less torque than the 3.5L EcoBoost V6. Also, fully agree about the lanekeep. I just bought a new F 150 and it didnt have it and Im not too disappointed. Why not just have the wheel have a touch sensor so it knows youre touching it without having to jerk the wheel every 20 seconds.

The truck has 4.10 gears, bad for fuel efficiency, but there’s a 10 speed automatic, with several overdrive ratios I’m guessing, what are the revs at highway speed?

It's a real shame that warnings pop up, there should just be one warning when you start and that is it, the whole purpose is for the cpu to take over, why have to fight what it is doing? If anything input from the driver should set the cpu to shut off!

I have a 2023 F-150 Tremor 402a I can't stand the self-driving stuff I turned it all off even the cruise control drives me nuts it can't seem to decide what the speed limit is

13.7 all around. 30000 miles some towing

I bought a Hyundai palisade and it has lane keep and adaptive cruise it depends on my mood if i turn it on or off but yeah it’s annoying all the messages. There is a thing called too much technology

So what is the point of assisted steering if you can not give your arms a rest on a long drive? It instead seems to be designed to help the aim of those drivers who can't actually drive between the lines.

God those front ends keep getting more and more hideous by the year

Thoughts on the auto braking? I turn mine off.

We have a 21 RAV4 and the lane keep is off. We also have a 24 Mazda 3 and we cant turn it off and it is a pain.

Big displacement v8 always over deliver on highway drivings, 14 is actually align with my past experience. However, that 7. 3 will cost an arm n leg if driven in toronto bumper to bumper traffic. I prob wont go with the gas engine if I tow over 10k lbs constantly. All about how do you use the truck.

Pretty sure my 2017 f150 5L says I get 14L/100km.... yikes
