I was a die hard diesel guy but I ended up going to a 7.3 gas F350 with the 4.30 gears. Biggest down side is no exhaust brake. I tow about 16,000 lbs every day during the summer. It gets about 1 mpg less than my diesel. I also shut out gears 9 and 10 which increased my mpgs because the trans was not hunting gears. Also helps keep the trans temps lower because its not shifting as much. Will it out pull a Diesel? Nope. Will it get me from A to B with a cheaper bottom line not only in purchase price, less maintenance expense, and cheaper repair bills? Yep, and thats money that goes back in my pocket. At the end of the day you have to get the truck that works best for your needs, this set up works for me.

"Diesel's days are numbered" not because the gas engine is a superior platform but because the government is doing all it can to hasten its demise.

Love your videos, very well documented and articulated.👍👍👍 You are doing all the homework for us, thank you!

I am waiting delivery of a f250 Lariat after watching your videos. Great job!

I was wavering...considering going back to gas considering the advent of the 7.3. This video reminds me why I bought my diesel in the first place. Much appreciated!

I pulled a toyhauler with a 6.4 Hemi, and it did an admirable job, even handicapped with the 66RFE. Went across the scales at 23,160 lbs. I tow at 65 mph, and it generally hovered in the 7.5-8.5 mpg range, hand calculated. I went back to a Cummins, and it was night and day. Set the cruise and relax. The Aisin seldom dropped a gear, and always stayed cool. Hottest I saw was @180 on a 106' F day on a 6% grade. Down long steep grades absolutely drama free, and almost never touched the pedals. Right around 10 mpg with same setup.

New 7.3 sounds promising. I have a 2023 GMC with the 6.6 gas and I’ll be honest it’s gone well above my expectations. I also have a 2015 Duramax but the 6.6 gas is no slouch. I hauled some cattle to the sale barn a few weeks ago and was loaded to 26K GCVW. I live in western Kansas where it’s flat but it pulled the load no issues and the best part is I averaged 10 mpg on that trip. My diesel only gets marginally better. It would hold 6th gear but I kept it in 5th just to keep transmission happy. I never saw the trans temp get above 160. I think the new 10 speed will wake it up even more and compete with the 7.3. What I’ve noticed is the 6 speed is lacking from 30-45 mph under load then picks back up again, whereas the 10 speed should help this. In my opinion unless you are towing all the time or in hilly areas the diesel option makes less sense especially with higher fuel costs. I enjoy you’re videos.

Awsome content. Another channel I watch called Ford Funatic has gotten me motivated to get a gas truck. A supercharged 7.3 for me will be an excellent tow rig and probably get 15+ mpg not towing. Thanks for the reviews!!

Great job J. B.!!

Love seeing you drive across Pioneer Crossing... 18 year SS resident. I'm in a 21 Powerboost and looking at a 7.3 F350.

I have a 2015 F350 4 Dr long bed dually 2wd. I ran from East Texas to Portland Oregon got an avg of 17.6 mpg. I hooked up to a 2015 Eclipse Attitude 43 foot toy hauler towed it back to East Texas with an avg 10.1 mpg. Driving habits make all the difference in any vehicle. I'll never buy a gasser for heavy towing. Weight was 24,100 on the trip back.

Love those views of the mountains!

Thanks for the review. I have a diesel 3500 and pull a 12k 5er. Although the 7.3 liter Ford is intriguing, there is value in the safety of being able to use truck stop lanes for refueling. Also, with the EFS fuel card the price of diesel versus gasoline is a wash simply due to MPG.

Not me, im glad we took delivery on our current 2017 ford f.350 diesel brand new back in late 17. We are full time rvr on the road since January 2018(and counting) and we've been pulling our 33 feet 10k trailer rv. The truck now has original 118,000 miles with only basic maintenance i performed myself while camping in the mountains or the desert. We are now moving up to a 20k 3 axles 43 footer 5th wheel toy hauler to keep on our travels as we like to have our toys and some equipments along. We sure glad we bought our diesel truck back then and we'll be keeping our $$$ instead of purchasing a new much higher price tag of diesel truck today.

For weekend towing a couple hundred miles the gas would be a great choice .

Yep. I prefer the gas pickups of today. Diesels have gotten way too much of a pain in the ass to work on and keep running, atleast for the uses I have for a pickup. The manufacturers still keeping with the v8 diesels really need to consider tilt front ends, or just make straight 6s and call it good. Now I have a couple old diesels and love those things, the youngest one is over 30 years old and 300k miles and still runs like a top with very very little work. I got two 8.3l Cummins and a 7.8l Ford L6.

You should do a video on how overloaded some of these real world scenarios I see driving up and down I-75 are. Just last night I saw a Nissan Armada towing a 30’ (+/-) trailer. Their headlights were pointing their way to heaven. Obviously they were WAY over their payload capacity. This is a number that is grossly overlooked but should be the FIRST number we look at when buying a trailer. The common mistake is to look at “what it will tow” (towing capacity) instead of “what it will carry” (load capacity or load rating). This can be a costly or even deadly mistake. Not to mention that if you get into an accident the insurance companies (both yours and whoever you hit) will be running the numbers on your tow vehicle and what you are towing. If you’re outside manufacturers load and tow ratings it will open up a can of worms you don’t want opened.

Good morning JB, I would love to see a MPG run between the GMC and Ford over 100 miles and I would really like to see the MPG hand calculated. I know that this requires time and money but I feel that would be more real world testing. I would also like to see the Ford with the 4.30 gears pulling that 5er instead of the 3.73. There is a place for both trucks in todays market and that’s clear but I would love to see some grade testing up I80 from both the gasser and diesel trucks. That way people can see the mixed driving and you can also show the exhaust brakes for each truck. I definitely could’ve bought a gasser but I drive the mountains empty and pulling a trailer and really like the ease when pulling grades with the Cummins HO. Thanks for another great video.

My former neighbor was a Ford salesman. He said that most people who think they need diesels would be better suited with a gasser. If he knows you he will try to tell you that the diesel would be wasting money but if you’re just a customer he’ll sell you whatever you want. Commission on diesels is a lot better. The Godzilla V8 can 5th wheel tow up to 20,000 lbs. So unless you’re towing more than 15K on a regular basis, not once a month or just a few miles in town, then the gas engine is best. Diesels don’t do well putting around town, that’s when you get emissions problems. TFL Ike Gauntlet test when they’re towing 25K up a mountain foot to the floor just to maintain 60 mph is what a diesel was built for. They live to be pushed hard. No regen needed because you’re doing it with your right foot. What slowly kills them is the run from the house to CVS to pick up a prescription. Engine revs barely getting above idle. Same thing with a 10,000 pound trailer, it’s not enough weight for a modern diesel to even know it’s there.

Thanks for the GREAT REVIEW 🍻

Still own my 1999 F350 which I bought new. The 7.3 engine is noisy. However, It has handled EVERY LOAD I had to carry when I had my own MASSONRY COMPANY. The truck is still running well. Only had one problem when the "camshaft timing sensor and the control board went south, this repair cost a little over $1.2K. Oh yes, The steering column pin broke. It cost me a little over $1K. My Granddaughter said; I WANT THE TRUCK!

I know from my own experience towing with a diesel or gas that 60 to 65 is probably the sweet spot for fuel economy. I usually run about 70. The difference between 70 and 75 is astounding. It seems like the point where the wind resistance gets a whole new multiplier. Great job with this content. Keep it up. I made the switch to gas a few years ago and I couldn't be happier.

I have a 3.0 diesel 21 Sierra and I cannot wait until the lease is up to get in a new 23/24 super duty with a 7.3! Love your videos, keep them coming!

Good video as always!!

Thanks sir for providing us perspective! Appreciate your time! I have a gas truck now. For short trips I think it is great. But I miss a diesel for long trips. Just no comparison on my opinion regarding how well diesels work under load. I want to get a duramax for my next HD rig. But gotta say that my older 5.9 Cummins seemed to love pulling heavy weight more than the Ford. I am curious how the new GM 3.0 with max trailer and 3.73 gears front and rear would be for smaller trailers? I bet it cranks!!

Take the 1000lbs difference from the diesel to gas, and add a good brush guard and winch. Will weight the nose down, but still won’t be as heavy as the diesel. The lighter weight does help when you’re driving through a wet field, doesn’t bury the front end.

My 2021 F350 has never down shifted lower than 6th to 7th on an 8% hill will maintaining 55 mph and not even full throttle. That gasser is screaming. I remember those days. Don’t miss them at all

Diesel seems alot quieter in the cabin. For long distances with a family keeping engine noise down helps.

That droning sound out of the V8 drives me nuts. One of the many reasons I switched over to the Diesel. I can afford the diesel and fix the diesel so the Diesel I will own🤙

My F-350 7.3 truck has the 4.30 gears . It tows even better than that truck .😊

I hope you do as many tests and drives on a gmc with the 10spd when it comes out. I'm considering this ford for a 5th that will weigh close to 10k. It would be a tuff transition but at least I'd be legal with pin weight. I would like to see if an exhaust and a different air box would help at all. That would be a video you would get alot of views on.. good vid

I do not regret having my diesel. I have found it to be much quieter when towing versus Gas. When towing long distances over hilly terrain it makes for a nicer experience. I have a RAM H/O AISIN and the thing is a beast. For me even though the Ford 7.3 could have towed my current Trailer it was more important to have a platform that would allow me to upgrade into a larger trailer safely versus buying a truck that was already considered maxed regarding its Capacity. It shame honestly diesel has gotten such a bad rap.

I live in Utah too and I’ve never had to plug in my truck in the cold or have had the fuel gel up. The thing gas will never catch up on is overall torque. My 6.7 PSD can tow above 70 lol. Would be fun to compare both trucks in person

Thank you for the review, great information. While the Ford gas was impressive on its MPG number, I have historically found that gas engines shift a lot more than diesels and pull much higher RPM’s when pulling grades as they simply cannot produce the torque numbers. You commented on low er RPM numbers on what seemed to be flatter ground. What is your feedback on pulling grades on the gas vs. diesel? If you needed to pass which one would you rather have? Thanks

Will be interesting to see what happens at 100 degrees with ac on and fan clutch locked on good grade.

7.3 is a beast!

I am always amazed how people complain about modern diesels and there emissions. I have been driving diesel pickups since 2000. I had a 2000 ford 7.3, 2001 dodge 5.9, 2005 dodge 5.9, 2007 ford 6.0 and here is where the power started and so did the emissions 2012 6.7 ford 2016 ram 6.7 and my 22 6.7 h.o ram out pulls them all and it's stock. Every diesel I had before 2012 I had to modify it to pull hills at highway speeds. Preemissions diesels were slow stock. I'm on my third truck with def and filtered exhaust and have not had a single emissions failure. Maybe because they were all bought new and I only run def from a jug I keep my def tank full and I only by diesel where I know it moves in high volume. And I don't mind clean smelling exhaust when we are in a campground. But it was fun rolling coal In my 5.9s with a 6 speed manual.

Love your video !! What’s the GCWR on that Ford?? Thanks

I have a 2022 F350 with the 7.3l and 4.30 gears. I average 12-13mpg daily, unless I try to stay under 60mph, then I could sit around 14-17mpg but I really need to try. I towed a 13,000lb 5th wheel and I averaged 9-10mpg and I ran pretty fast half the way that trip. 70mph, sometimes 80mph. At 60mph it stayed the same. I was pretty happy about it. But then I just recently pulled my 11,000lb bumper pull rv and man did it drop. Flat roads I stayed around the 6-7mpg range at 60mph and the real long hills helped me coast a lot and I stuck around 9-13mpg, but it's a ton of coasting. I pull a 5,000lb towable boom lift a lot and it still get around 8mpg. I've pulled a 8,000lb gooseneck dry a couple times and I get about 9-10mpg. I believe bumper pull has always dramatically reduced mileage because of how it pushes a truck around. A 5th wheel or gooseneck doesn't have that leverage with the weight behind the axles, so it's very smooth and easier to pull regardless. My transmission Temps stay around 220-225 degrees if I'm towing or not. Idle I'm around 214 degrees. If I have a heavy load, it doesnt go above 8th gear until Im doing 70mph. Rpm didn't need to go higher than 4k uphill unless I tried to floor it. Flat ground I was around 2300 rpms or so Truck is as smooth as I expect being that it's new, but I hate bumper pull. Truck comes with a 2.5in receiver so you need an adapter to use most hitches and in doing so, you get a lot of play. Towing above 10,000lbs I feel it wanting to wiggle and sway on me a lot with just a little wind outside. I highly recommend ordering a hitch with the right size to avoid that slop. It drives me nuts. I do wish I went with diesel, but I'm not upset with the 7.3l. I tend to get a heavy foot if I'm not towing and the diesel is much more expensive in initial buy and maintenance. I always hear the diesels getting 18-25mpg so their fuel costs are slightly lower even with Def fluid included. But it's one of those things, once they have problems, how much more will it be. As to a simpler engine with less parts needed to replace when things go south. I don't tow over 8,000 lbs often so it's not necessary for me to go diesel, it's simply a want. My truck sounds great at cold start but then is super quiet once it's warmed up and that is perfect to my liking. So far, 55k miles in just over a year and I haven't had any issues, outside of brakes slightly squealing since day one. I don't run aftermarket bumpers or any extra weight on the ends, outside of a 500lb welder in the bed everyday. Hope this helps with more insight.

We will be getting a new Super Duty F350 with the H.O Power Stroke in a couple years. We will be on the road the majority of each year towing a Fifth Wheel. I really would prefer the 7.3 Godzilla and didn't want all the extra not fun things with a diesel. However, there is one item that you just can't get around that had me to go the diesel route. It is nearly impossible to find gas pumps with enough room to get a big rig in and not do any damage. With a diesel, you just use the semi lanes, the TSD discount card and then move out of the way and park if going inside. That is the sole reason I am going diesel and it is a huge enough reason all by itself. Towed for many decades with all kinds of rv rigs and getting fuel is the one place you can avoid mistakes by being wise.

Thanks for the great video. I have owned diesels in the past and tow campers, and I have 2 complaints against the gas, fuel economy, and the exhaust brake. I tow mainly in hilly county and was wondering about navigate the hilly country with a gas, thoughts?

Need to step up the MPG game, TFL does a good job. My DIC is anywhere from spot on to 2mpg off.

The company I work for has multiple large F-650 based 24 ft box vans at my facility. Some have the old 7.3 powerstroke diesel. A few have the Triton V10 and our new ones all have the 7.3 Godzilla. Even having 75 hp nerfed off them vs the ones that come in pickup trucks, the Godzilla is easily keeps up with, if not beating the diesels and are much more refined and nicer to drive. The Zilla and the new transmissions have basically elevated the performance of heavy duty gas engines to that of diesels from 20 years ago. They won't keep up with a modern diesel with a heavy load since they're not forced induction but if you aren't pulling 20k lbs in the mountains on a regular basis, there's really no justification for shelling out the extra coin, not to mention all the government mandated emissions crap for an oil burner anymore.

Very much agree on the Tire statements. Conti needs to pickup their game.

I knew it, JB! At some point you would come to the Zilla side! I'm sure that there are plenty, but I have yet to meet any unhappy Zilla owner. Ford, GM, Ram all do stupid stuff, and practices some stupid stuff, but Ford did hit the ball out of the park with the Zilla package. Zilla w/ 4.30s cannot be beat within the gas realm. The tranny is designed for heat, by the way. Actually, you can do more damage to the tranny when it is below temp. Great videos, as usual Sir!

I’m looking at 1 of the big 3 to purchase a bare bones option from. Regular cab dually with a V8 for my new cab over camper.. the price difference is 20 grand from a diesel with a few options. Just not sure which V8 I like most yet, they all have a charm to them.

Like the option of the big block gas engines. I tow between 20-25k on my diesel, at that level diesel is a must in my opinion, the way they can handle that weight is unmatched by any gas engine. But if I towed less weight and less times per year these are an option.

The sound of that engine is intoxicating. Also, Ford transmission like to run hotter than others. The programming for the electronic fan clutch engages it for transmission temperature at 240.

JB, I think you are underestimating the winter capabilities of diesel trucks. My HD Duramax doesn't need to be plugged in until the the outdoor temps reach 0 degrees and even then it will have no issues starting. For model year 2022 and newer GM has redesigned the DEF heater circuit so freezing DEF is no longer an issue. As far as fuel gelling, here in Vermont and in other areas, winter blend diesel fuel will resist gelling. I do give my truck a splash of Howe's anti-gel additive just for peace of mind.

I get about 14mpg towing my 9,000 lb trailer in my 2019 F250 Diesel. Around 18 when not towing. YMMV.

You can’t use the computer for MGP while towing it’s usually way off. My 06 Cummins shows 17mpg towing but actually get around 11-12.

Only issue is the 7.3 godzilla has had quite a few lifter/cam failures by 40,000 miles…hopefully they have rectified this and not ignore the issue for many years like gm.

Great video. What is the axle ratio on your gas 7.3

Does that model have the camper pacakge? Just ordered mine with it and hope that rear sway bat was the right choice

Now if we can just get more Buc-ees or Costco stops so it’s easy to get gas for those who switch over. I think I remember some of the stations out west having RV gas lanes which was nice. Diesel is still high out west! It was 3.70 this morning here. 🇺🇸💪

What speed do u run your diesel at 75 when towing? I would run them back to back at 60 or whatever speed u would tow at

I’m coming from small trailer and now looking at getting a 5th wheel. How big of a deal is it for 5th wheels and needing to find accessible fuel stations? Going from diesel to gas, how big of a loss will it be not being able to utilize truck stop, big rig lanes?

Major upside - You can see the ground when looking into the engine bay. It meas I can work on the 7.3 without having baby hands. My diesel engine compartment was packed so tight I could hardly do any repairs myself. Even with dual batteries, I can reach everything on the 7.3 engine compartment.

I'd say with this scenario towing that weight with that truck running 60ish is more than enough. Better to be safe than be fast.

My 20 year old Chevy 8.1 gasser pulls my 16000 fifth wheel through Montana passes, but you know it's back there. Chevy needs another big block introduced to keep up now

I have the 7.3 in my E350 work truck and I get 9.3 Mi to the gallon. I tow a 10000 g v w dump trailer and it really dogs it down. My vw mk4 Jetta TDI pulls my snowmobile up the mountain with way more ease.

great video

Wow it's beautiful there

There are pros and cons to both gasser & diesel trucks like the payload Cap. & unlike diesel you only have to worry about gas and not def. but then if your towing a lot I personally like my Diesel better because of the exhaust braking it saves your brakes not only on your truck but on the trailer as well and save on your transmission VS the gasser where you only have the tow haul mode that uses the transmission to help save you from ridding your brakes. Also why would you drive 75 MPH towing your trailer, we keep it at 65 all the time to save on gas and if we have to slam on the brakes then it doesn’t take as long to stop!

Just my opinion. I order the Diesel F350 HO. My thought is, it will be a relaxing 5th wheel tow and I can safely carry a 58 gallon transfer tank. I wouldn't do this with gas. I will probable tow 10K per year. I need a gas and diesel truck lol

I think it's interesting you said 8 would be good in this truck. I pull a 5000 lb travel trailer with my 2013 chevy 1500 with the 4.8L and 4 speed transmission and get 8 mpg the majority of the time. I think you're assuming wrong when you said they think of the people in it when they figure the numbers. I don't think they do.

I tow a 10,000 lb travel trailer with a 17 duramax. The truck has 105, 000 miles on it. It pulls stronger now than new. The fuel economy gets better with miles. I average 15 MPG towing that trailer. I pull 8,000lbs daily and average 16MPG in the mountains. The MPG on the gas truck is going to have to get better before I switch. But I do tow daily. Like you say, if you tow occasionally, it may be ok.

Hi. What was the rear diff ratio of your test truck. Thanks. Rob

I'll keep my paid off 6.0 Power stroke. I've had the truck for 5 yrs and would only loose a couple of thousand if I sold it (that's including the work I did to fix it right). I also can get 13-14 mpg when towing.. you'll do 7-8 mpg tops on average. Even with higher fuel pricing, the Diesel is still cheaper per mile. I get where you're going and if I didn't travel long distance much, the gasser might work. Our average pull is probably 5+ hours so I'm probably going further than most.

I just want to carry a cabover camper, and tow a 20' bass boat behind. Is this gasser the way to go?

Love the video's, but you need to go on longer runs for a more accurate snapshot of MPG, plus hand calculate and not rely on the computer.

Where are you in this video? Beautiful mountains

After having a 21 f250 with the 7.3 I can tell anyone buying one to tow with it to .ale sure you get the 4.30 gears. I towed a 9000lb travel trailer with mine. My brother in law bought the same truck as mine but with the 4.30 gears. His 5th wheel was 12000 lbs. I was getting 7 mpg towing across MD on 68, truck never got above 8th gear unless going down hill. My brother in law's truck was consistently in 9th getting 9.5 to 10 mpg same route. I loved the truck (first new one in a long time) but, I messed up with the gears. If you find one with the 7.3 and 4.30 gears go for it

It's very rare to see a payload sticker that shows a lower number than the actual weigh scale. The manufacturer's placard does NOT include the weight of passengers. Thus, there must be some other reason, perhaps an error of some kind on one of the weighings or maybe there was extra equipment in the truck that was missing at the time you weighed it (ie spare tire/tools, integrated towing tools etc) - just naming a few possibilities, OR a mis-calibrated scale (which is more likely the case).

Nice video. That seemed pretty hot for the transmission, especially on a cold day. That could be a reason Ford is pushing the 4.30 gear for their max towing numbers. I’m going to be interested to see how hot it will run with a 4.30. The hottest I’ve seen my Chevy with the 6 speed is 209 but that was 99 ambient temperature and pulling a 2 mile long 8% grade. As for fuel mileage, I would say your way of checking it would be the absolute tops to expect with pure highway driving, but that 6.9 number would be more likely for a full tank of towing. Which is not bad. My experience with gas vs diesel is the gas gets 2 mpg worse.

The 7.3 really should be paired with the 4:30 rear but the 3:73 is a little better on fuel unloaded the 4:30 is better loaded.

Straight up. I pull a Reflection 260RD that tops out at 9995lbs GVWR and love pulling it with a GMC 2500 6.6L SLE gasser. Traded in my 2020 Ram 2500 diesel after having suffered way too many emissions related issues with these new setups. 95% of my pulling is in the south around Louisiana with the occasional trip to Tennessee. Thing is for me the repairs are easier and much cheaper than on these new damn diesel trucks to the point even I can do them and parts are 1/4 the price. Don't get me wrong. The Ram was a beast. I just think the emissions on these trucks now days don't justify the cost now. Way too expensive to purchase and way too expensive to repair. Also if I ever have an issue with that L8T on the GMC then my replacement will me a Master Motorsports built L8T for 12k that pushes 600HP and almost 550lb's of torque.

FYI I have a 2008 6.4 Diesel any my trip mpg calculator is always about 2.5mpgs off from filling and calculation manually. I have never got the reading that that gauge on the dash says. So unless you feel strongly that the trip mileage is correct I don't and most ppl says the same its always off. BTW I subscribe to you and think you do a great job. So don't take this negatively .

My dads 2015 gmc diesel ran at 1750 rpm at 65 mph with 6 speed transmission pulling bumper pull toy hauler that weighed about 8k

Great video, I am really surprised how light the axle weights are on the Ford! It would be nice to do a head to head comparision with a diesel Ford on the curb weights. I have a 2017 Silverado HD Duramax that has a ranch hand front bumper and 18k winch as well as a 60 gallon fuel tank in the bed and my truck weighs over 9200 lbs rolling down the road and my front axle weight is very close to 5600 lbs. When hooked up to my Grand Design Solitude, I am usually at 7000 to 7200 rear axle weight and my front axle is still at 5600. Due to the extra fuel tank and winch/bumper, I am exceeding my GVWR. I have thought about upgrading to a dually, but believe it or not my capacity won't go up a whole lot even having a dually because the truck will weigh more to start. I am at 88k on my truck now and as good as it looks like the 7.3 gasser is doing, I am interested in seeing how it does is warmer temperatures, like 90+ because cold outside air makes much better power than hot air. Also note that if doing mileage testing, winter fuels don't get as good of mileage as summer fuels both gas and diesel. Diesel is much worse in the Rocky Mountain region because of the formulas to keep the fuel from gelling in the winter time. This also affects power in the winter also.

Dude couldnt agree more, the new HD gas engines are capable, 50% price increase on diesel over gas, DEF...$12k premium on the engines...for 70-80% of the market people could now have a gas engine and be happy. I have 2 2023 F350 Tremor Lariats on order (7.3l and 6.7l HO)...I already got notified my 6.7L HO will be built mid February...no word on the 7.3L. I will end up passing on the 6.7L as I think this 7.3l is a better option for ROI on your money. Here is what I really want to see...how does 7.3l hold RPMS towing a 5er at 65-70mph? I want to see how relaxed it is. Got any videos of that comparing gas vs diesel towing RPMs when steady state roads?

I got 10-11 mpg with my 22 Duramax, towing a Heartland 38’ 13k dry, from New Hampshire to Alabama.

7.3 oil pump is on a timing chain outside of the motor. ???

That 7.3 godzilla is a torque machine. It sounded kinda "Mid" to me at first but knowing it has a 10 speed and for it to tow an impressive amount for a gas engine I kinda like it now cousin of mine has one and here I am debating between the godzilla and the beastly 6.7L HO

Have you actually done an at the pump calculation for the fuel economy rather than just looking at the computer? I have always seen them be a couple MPG off (in both directions).

I have a 2023 F250 Crew Cab 10,500 GVW 4x4 that has a 3819 lb. payload capacity. 11.6 Sterling rear end, 7.3 Godzilla motor, 4.30 gears. CGVW is 26,000 lbs. I shouldn't have any troubles towing a 5th wheel up 15,500 lbs. if the max payload is met.

I wanted to make another comment about something I observed in the video. And also point out this F350 does have a 3.73 rear gear. I’m not sure if JB ever has said that but it does have the 3.73. Anyways when he was trying to accelerate to 70 or 75 mph and then said he couldn’t, the truck was in 4th gear and turning around 4500 rpm. Now this would be the sweet spot for power for this engine because that’s slightly above peak torque (4000 rpm peak) and a little below peak hp (5500 peak). So in other words it’s not going to get much better than that for power. He never said, but I’m assuming JB was WOT because he said he couldn’t accelerate AND the truck wasn’t downshifting even when the speed and rpm started to fall a little. Now I’m sure some would say if he had the 4.30 gear he could have accelerated. I don’t think so. If the 3.73 wouldn’t give a downshift to 3rd in those conditions the 4.30 certainly wouldn’t (it would have been in 5th actually). And considering he was between 4000-4500 rpm and still not accelerating what good would the 4.30 have done? It would have possibly been a slightly lower RPM and speed because it would have been in 5th gear instead of 4th and had a final drive of 6.53:1 (5th gear for the 4.30) compared to the 3.73s final drive of 6.61:1 (4th gear for the 3.73). So in that particular instance the 3.73 is atleast performing as good as the 4.30 would have, arguably better. And that’s towing a pretty heavy trailer.

I knew that that Godzilla was going to be a beast. For one, Ford went back to a pushrod V8. Plus all the time, money, and testing that Ford did with this engine. Ford wasn't playing around. They wanted a proven engine when they released it for production. And with the EPA's war on diesel engines. I'm sure that Ford wanted a capable gas engine. Sure, it won't be a brute like a diesel engine. But it will get the job done

Having towed with a gas 6.4 hemi. The next thing I will look for in my next gas tower is the larger fuel tank. The 48gal that comes in the long bed f350 crew cab is a big benefit. You are limited trying to fill up a gas motor hauling a long travel trailer or 5th wheel.

7.3L will pick up around 2 MPG with a low restriction cat back exhaust. I think MPI Performance exhaust offers the best system. Also makes a V8 sound like a V8 should, but not obnoxious.

Had to get rid of my 2020 7,3 for a 2022 diesel for the pulling power of the diesel and mpg no comparison to the diesel had both

Why not superchargers on the gas trucks from the manufacturer?

Does anyone have an idea about the 7.3's reliability?

Jb I heard the new 6.7 cummins gas engine will be around 500 horsepower and 550 ftlbs of torque any thoughts? News?

What gears are in that truck

15 cubic inches from a 7.5 460, I guess it wont be long until Ford makes an actual 460 with 480hp/550tq comes out

Just a good ol godzilla

For the up-charge to a diesel you could add a supercharger to the 7.3l and gain more horsepower than diesel with lower maintenance. Albeit, you can't match the torque and longevity of a diesel.

Well if diesel daysbare numbered so is those gassers.. why that motor pulling same as a deisel will not last 300k prob be worn out by 200k
