Thanks for watching! Check out our road trip MPG results with a 4.30 rear differential on TFLnow: kzfaq.info/get/bejne/kLWVopRz27e7enU.html and our off-road Tremor gas vs. diesel comparison on TFLoffroad: kzfaq.info/get/bejne/q82cl91_z9u7oqs.html

If port injection is "old school" I guess carbureted is "prehistoric".

When towing. Ford 7.3 = 5.65mpg Chevy 6.5 = 6.9 Unloaded Chevy = 16.0 mpg Ford = 15.1

That amazes me, these new heavy-duty trucks get better fuel economy than my 2004 hemi 1500, technology has come a long way in 16 years.

Smaller engine Chevy with less geared six speed still did better, despite a slightly heavier trailer... Now that's impressive.

Finally the Embargo is over!! Can't wait to see more videos about this truck! Keep up the consistent hard work TFL!!

I have always said it, ford’s numbers on paper are always the best, but in real world everything changes

They should've tested these two with the same trailer, on the same day. Guess we'll see how it does on the ike gauntlet.

Both of them get better empty mpg’s than my ‘05 Tundra! But it’s paid for and suits my need.

Wow. Didn't expect that outcome. Obviously they can't really match the rear gearing between the 2 brands, but 15.1 out of the Ford on the new 10-speed versus 16.0 out of the Chevy on the old 6-speed. That's an impressive finish for Chevy's new 6.6.

Love Ford bringing big displacement back but I'm with Andre on this one, I expected better.

Nice video guys. One thing I notice when checking gas mileage on my vehicles over the years, is that ambient temperature and wind can make a huge difference. My driving usually takes through Ohio, Kentucky and Tennessee so I often see major temperature swings. As the temp goes down so does my mileage. I would really like to see the F-250 test on a warmer day. Enjoy your videos and commentary.

Not bad, 20 years ago, I used to have a 97 4x4 f250 with the 7.5L, a 5 speed manual and 3.55 gears. Best mpg I ever got was 13.5. This was with 285/75r16 tires. Most of the time 11-12mpg. That engine was rated 245hp and 410tq. So now we get more power and better economy.

Interesting result. The result is consistent with what I would expect. Chevy does a very good job of squeezing efficiency out of their vehicles. However, I would not let a relatively small (really within the margin of error) difference in fuel economy be the deciding factor between these two trucks. There are many other considerations in my opinion. Either vehicle would be a good choice and I think that personal preference in styling and design will likely be big factors in peoples purchasing choices.

The 7.3 is kind of falling short in every category for me. Less torque than I expected, less fuel efficientcy than I expected so far. The Chevy is actually doing quite well considering its using a 6 speed.

Glad to see you are finally able to do mileage for the 7.3. Not real bad mileage for that big monster of an engine. Thanks for sharing Andre and Kent enjoyed the review.

It is pretty tough to split mpg tests over several days. Each leg of tests, on both trucks, should be done under near identical ambient conditions, meaning that each leg should be performed at nearly same time on same day. Temperature, atmospheric pressure, humidity, wind and fuel mix all play a role.

Looking forward to the ike gauntlet!

Omg my dad used to work for Cimarron Trailers in Chickasha, Oklahoma!!!

Thank you guys! These real world reviews are truly a God send.

Really enjoy this and all of your videos, you guys are great!

Great comparison and you're the only one doing doing towing tests. Like to see you add coolant temp and EGT to your tests. EGT is usually a diesel thing but towing it would be interesting to see how gas exgdust temps under load.

Just want to say you guys do an amazing job all the time! For future comparison videos, would it be possible to film both trucks on the same day with Mr Truck in the other vehicle to eliminate variables like the wind and weather conditions if it could be done logisticly.

I had a2500 Ram power wagon and I loved the engine in it, it was a 6.4 gas and it would do anything that I needed it to do. Love love love the power wagon

Thank you very much for this video. Now I just have to wait a couple of years to see if either one comes up with problems. Both of them do better than my 2500hd 6.0. I get 14.5 and never go over 65 mph.

These MPG numbers just make me want to hold on to my 1996 Cummins 12v even more! Lol

Good review. Thanks. Thinking instead of new truck, reinvest in my truck. 96 F. 250 w/460. I can save lil gas and a lot of 💰 when new one is 50K

Keep those 7.3 tests coming. Thanks.

I love this show. First its a great show , Second these guys are local and its a lot of fun recognizing all of the places they go..... Like the Love's station in Hudson and then driving around the Front Range in Longmont and boulder

Air temperature also makes quite a bit of difference in MPG comparisons. I used to have a Ford extended E-350 with a V-10. In cold weather (20 degrees F) it'd get about 13 MPG with about 3500# of cargo. In 70 degree weather, it'd be up to 16 MPG. If your comparing MPG you have to keep the conditions the same as possible. Also the MPG with a gas engine may be lower, but cost of maintenance and intital cost compared to a diesel is also lower. I've got a diesel that I pull my 5th wheel camper with and I love it, but I don't think you ever get you money back. Thank you for all of your great tests.

Very similar mpg's to what i seen in my old 2500 6.0 Silverado with 4.10s when it was stock.

"we had some wind" wind makes a huge difference.

this is the most important youtube channel for truck buyers

What concerns me is longevity on these 8 and 10 speeds, they do a lot more shifting especially pulling or driving in the hills. Maybe I'm wrong but my basic knowledge on transmissions make me thing more shifting= more wear and potentially more heat?

6:24 Semi truck fuel economy

Thanks for this great test!. I own a 2017 F-350 SRW Diesel and have tested how MPG suffers as a function of speed and strong headwinds. This includes driving through stretches of Utah which permit 80MPH (85MPH is not challenged). With no trailer, the MPG loss between 60MPH and 85MPH was ~30%. Strong headwinds hurt a lot as well, and diminished your F250 trailer test. Still, I'm disappointed by Ford's MPG. Being purpose built for trucks, I expected better from the 7.3.

Depending upon the wind - that can really kill mileage. My F350 with a camper averages 12.3 with no wind. On a windy day the mileage can go as low as 9.5 MPG. You need to re-run the test on a day with no wind if you can do that.

Good video, interesting results. Both ford and Chevy will still be my favorite 2 truck brands

Hey @The Fast Lane Truck, Can you do this test again with one of the higher level 7.3L Super Duties, with ECO switched on and off in both scenarios as a comparison? I'm curious if that actually makes a difference! Thanks, Awesome content as always!

Well I just ordered a 2020 f350 with the 7.3 and I can't wait. I don't get trucks for gas mileage but I'll take 15mpg.

Glad u guys went with basically a work truck trim f-250 gas it’s something most hard working people could afford rather than a platinum good job

48 gallon tank! I I can hear my bank account screaming now 😅

Not unreasonable figures, they might improve with break-in and summer blend gas

That mileage matches the best I can get out of my 04 5.4L F-150. I was one who expected a little more from the 7.3L, but Ford also has said that one of the major factors of going back to this big of an engine was the ability to work on it. They expect the majority of these to be fleet trucks and the ability to service/repair them quickly is a big selling point and saves a lot of money in the long run. It is made to house a big Diesel engine, but there is more room under the hood in that 7.3L then some V8 half tons.

Cant wait for the 4.30 gears test been waiting seems like forever

Considering it's a brick. 15 mpg ain't bad. The chev has a better drag coefficient. I think it'll even out on the ike, when aero is not a factor. 🤙🏻

If the 7.3 coupled up with a 4.30 rear end is any thing like my 6.2 gas it will do great.

Please run the MPG towing loop with this truck/Cimmaron trailer to see how it compares to the 7.3 with 3.55 gears.

I have the SuperCab F250 and I averaged around 15.5 mpg combined. I lifted it 4 in and put 37s on so now I’m at 12.5 mpg

Can we do the Ram 6.4l next??

I just can't believe GM made their truck look like a catfish.

Another great video guys!!!!! Thanks!!!

This is awesome battle of the Big Block V8 mate. Ford 7.3L Godzilla V8 vs GM 6.6L Ecotec gas V8.

I get 13mpg in my '11 f250 2wd w/ 6.2 gasser ... I'd call 15mpg a decent improvement.

I just can’t get over how damn ugly those chevys are. Goodness!!

My 7.3 wouldn’t get 15 mpg if you dropped it out of an airplane. Running around out in the pasture driving to town averages about 9 to 10 miles a gallon Drove it the other day on the open road with the cruise set at 68 miles an hour averaged about 13.1 with a 355. Still a heck of a lot better than my old 454. Technology has come along ways.

I think it’s worth mentioning the 4 door cab weights a lot more then a standard cab, sometimes by as much as 1000 pounds.

You can't compare tests from different times of year. You need to take into account winter fuel and summer fuel blends. Also air temperature will affect fuel milage. To compare they need to be tested at the same time under the same conditions with the same fuel.

If I was actually towing weight like that I wouldn't even bother with a 3.55 gear for the 7.3 engine

Only question is where did Mr. Truck get that jacket?!? Looks so damn good and I need it!

I would be interested in seeing a towing test done with the premium unleaded fuel just for interests on if the mileage gets better when using the high octane fuel. Thanks for the video!!

Since it’s mostly a freeway loop, the weight had less to do with economy than the winds and temps. The comparison to the GM at this point is purely anecdotal. Need same trailer and load with same atmospherics to get a reasonable comparison.

My father has a 2014 Ford F150. It averages 13mpg. Without a load. (Edit) His truck is lifted slightly and has 35×12R18 tires.

Those trucks get same mpg than my 2012 tuned dmax . Thats impressive.

Here’s my 1.5 yr. ownership experience with the 2020 Chevy 2500 experience below. Thanks guys for your test reviews of this and the Chevy. And for your honest reactions that I noticed Andre seemed to hope the Ford Godzilla would do better than the Chevy especially since the Chevy pulled a heavier trailer. I’ve sensed from other videos how Andre likes the “Godzilla” name and all. To keep this peaceful, both essentially get within 1 mpg of each other, how’s that? PS, I own my 2020 Chevy 6.6L gasser and … love it thus far. I get 17-18 mpg US on Hwy and 14-15 city and worse for both in winter. I Love the 82” long standard bed, the front & rear side steps (plus the optional side mounted Bed Storage Boxes leaving 4 ft. Width in my box yet lots of storage = Awesome!!!) direct fuel injection engine with the JD Power proven reliability and beefed up 6L90 transmission for this new 6.6L. Because I live in an area that has +6 months of real winter, I appreciate the AutoTrac transfer case for more secure winter driving.

It shows that V8's are the same as they were 50 (or more) years ago, unloaded 15 mpg. Nothing new under the sun. :)

CHEVY WINS AGAIN....nothing beats a LS motor. I get the same mileage with a 6.0 w a 4.10.

I have watched many videos with truck comparisons. There are the Ford Guys, Dodge guys, and the Chevy men! When trucks come off of the showroom floors, stuff works. After 100,000 miles, let me see which trucks are still performing at a satisfactory level. New trucks have wat to many bells and whistle gadgets and that leads to more failures. I live in a harsh winter climate 5 months out of the year in the Upper Peninsula of Michigan. Mechanical door steps, multi use tailgates, auto tailgates, low profile wheels, fancy chrome trim, and lady features! All that stuff fails at -10 and in deep snow with a 100 Libs of ice stuck to the truck. Ford has tons of great tech! Dodge plenty of power with a Yugo transmission! And the Chevy with a check engine light. I got 240,000 on my 02 Chevy Avalanche and it lasted 17 years before I sold it. I bought a 14 Chevy WT 1500 with 100,000 and it works great. Not a lot of bells and whistles, but practical. I just want a rust proof truck, which the manufacturers can make but they won’t.

Just to put things in perspective, my 454 BBC with an NP 4500 gets 8.2 MPG on the open road, and 7.9 in town. So, your 15 and 16 MPG sound pretty good to me. --- Thanks for the great upload. ---

Yikes ! I think I’ll keep my 3.5 EB

I say re do the test in warmer weather like you did with the chevy

Love the video, a little disappointed with the 7.3 fuel economy. Hopefully it will get better once the engine gets broke in. Can't wait to see it on the Ike Gauntlet !

I have a 01' SuperDuty 4x4 with the 6.8 V10. With over 130K miles on the clock it gets 14 mpg at 65 mph empty and when I towed my 11,000 lb trailer from Seattle to Maine, I averaged 8.5 mpg for the 3,200 mile trip. My truck weighs 7,800 lbs empty. Considering that it is in great shape and paid for, I would be hard pressed to buy new when the fuel consumption numbers are not any better.

Your results are pretty much exactly what I expected; comparable but with the 6.6L doing a bit better. Direct injection is simply better from a pure power and efficiency standpoint.

Once again GM proves to have the best gas V8. The rest of the truck is still up for debate. I must say ford did good for port injection.

This interests me greatly. Diesel has been 30% more than gas in Canada and I'm not towing as much anymore.

Another great vedio guys. I don't recall. Did the Chevy also require midgrade fuel?

Finally! We have results! Nice vid guys. Imo, the ford could do better, a couple examples on youtube were achieving much better gas mileage but, the real world varies based on altitude, temperature, how flat the road is, etc Depending on where people live, their numbers can be better or they can be worse, im rootin tootin for the the big block Ferd!

So imagine gm adding a 10 speed to their new gasser. Might be better than 16 mpg.

I drive the same loop 6 nights a week I get 2-3 more mpg in the winter vs summer.

Nice trailer. 👍🏼👊🏼

$53,000 for any pickup truck is ridiculous and gluttonous. The rate that pickup truck prices have risen is absolutely crazy. I hope someone takes a serious look at this... It's right in line of paying $100 for sliced up jeans...

Now let’s see the ram 6.4 hemi with the 8 speed please!

Do you ever do a meet and greet for local viewers? I live in Brighton and love your videos. I could also be some ballast if you need a 290 pound passenger. 😂

Yay! Thank you guys!

Seems like they were making a lot of excuses for that F-250. 🤣

It's all physics when it comes to towing . Every truck is going to get similar mpg. What's more important in my opinion is brake distances, merge lane acceleration and overall handling.

I like Mr. Truck, he cracks me up.

Sags quite a bit at the back. Some airbags or extra leaf would work wonders for nice towing rigs like that.

Winter fuel and wind will kill fuel economy every time.

Ideally, the GM and the Ford could have been tested on the same day (or even at the same time, for the unloaded test!) in order to eliminate weather/wind as a variable, but we (unfortunately) don't live in an ideal world. I admit to being pretty intrigued by the new 7.3L Ford gasser, but it is REALLY difficult to compete with GM on OHV gas V8s... that has been their bread and butter for YEARS, with no forays into OHC architecture, etc... to take engineering dollars away from the OHC V8 program(s).

My 1990 f250 4x4 with the 460 gets 13.2 mpg driving at 60 mph. It has 165,483 miles on the original engine.

If you was to bump up the timing and get the engines burning the fuel better they could probably pickup a few mpg. Gm’s 6.0’s have always had minimum timing from the factory hence why they gain 50hp from tune alone.

@9:24 why was the F250 towing less weight than the Silverado...

Who want a transmission that's hunts through 7-10 gears all the time.....

Not tested under the SAME conditions.

I've never been a Ford guy, but you really can't go wrong with either of these brands. Chevy and Ford definitely make each other better.

So you’re gonna be stopping for gas about every 250 miles. “I needed to stretch my legs anyway.”

So much for the 10 speed giving it an edge... Also caught that they said the truck floated from 7 th gear to overdrive and back a lot. Maybe that's why GM kept the old 6 speed. These trucks were built for reliability first after all. I'm sure they are all making less power than they could too for reliability purposes.

Will you guys do an in-depth video on the new single speed transfer case GM is offering? How 'terrain mode' actually performs and if there are any major pitfalls for opting out of a true 4L truck.
