7.3 gas or 6.7 diesel?

[timf343]

The diesel is going to have a range advantage with the better fuel economy and has larger aftermarket tank options that are not available for gas at this time.

I echo what most others have said. 6.7 vs 7.3 is really a personal decision based upon the various factors that are important to you and your truck; all are relevant to the truck owner and may be totally irrelevant to every other single person on the planet. It doesn't help really answer the question other than to say there is no answer because no one else knows your intentions for your truck. I also weighed the decision extensively. For me, my main factor in choosing diesel was range.

A 50 gallon tank in the bed (tonneau and 5th wheel compatible) and 60 gallon mid ship replacement give me 110 gallons on board. At 12-21 MPG (my estimate of heavy towing to unladen), that's damn near the entire way from Las Vegas to Washington DC (a route I drive round trip 2-3 times a year) with just a single refueling stop, one I intend to make around Missouri for the less expensive fuel I always seem to find there.

By comparison, a 7.3L getting 8-14 MPG with the stock 34 gallons and no real replacement or auxiliary options is at least 6-10 fill ups if not more.

And no, I'm not driving straight through and stop plenty to stretch the legs and what-not, but the option to not have to refuel every 3-4 hours while towing at interstate speeds appeals to me very much.

Sounds like someone is regretting their decision

LOL Ya right.

Clearly youre not a regular on here (Your 87 reactions points confirm this), or dont read the threads, because its been discussed as to why I certainly made the right choice.

I Just find it amusing when guys who dont tow heavy or often try to justify their decisions to buy the stinky money pit named 6.7.

And lets be real, if you said "Hey, I dont need a diesel, I just want it and got what I wanted" thats fine.

But to try to convince us you made a sound decision buying a 6.7 to drive to work and back, or to take to the mall unloaded, shows just how silly some people are.

7.3 vs 6.7 Beating a dead horse

Hey guys - getting ready to order my new Tremor and I am really quite torn on engine choice. I've beaten this subject to death in the past when buying trucks, but there is something about the 6.7 that makes me come back and question my choices. Currently in a 1500 Silverado that works for what I...

2021 7.3 vs 6.7

Hi Guys, Im going down on Tuesday to order a new 7.3 or 6.7 F250 XLT with the Tremor package. I went to the dealer last week to order the 6.7 but the dealer was thinking the new 7.3 engine would suit my needs better. I plan to get a 30-32 foot toy hauler within the next year or two. There will...

Diesel is 2 seconds faster in quarter mile. Better fuel mileage. Better towing. Gets more chicks.

Only thing the gas motor has is it's lighter and costs less.

No it’s not. It’s a .1 and 1.3 mph faster. Oem tune.
“It's quicker than the 7.3, even though it's 674 pounds heavier than the F-350 Tremor we tested. Quicker than a gas-only Ram Power Wagon, too. Let this thing rip, and it'll hit 60 mph in 7.2 seconds and the quarter mile in 15.5 seconds at 92.2 mph. That's a tenth quicker to both marks and traveling 1.3 mph faster at the end.”
“Seems as if the new V-8 weighs less than the old one, though, despite being larger in displacement and cleaner and making much more power. Go, science!
The slightly heavier 2020 model hits 60 mph in 7.3 seconds before tackling the quarter-mile in 15.6 seconds at 90.9 mph. The 2017 beastie gets to 60 mph in 7.5 seconds and runs through 1,320 feet in 15.9 seconds at 88.8 mph.”

I also wanted all the payload capacity that I could get. Another reason I went with the 7.3

I got the diesel and believe that I will be happy with it. I don't meet all the specs a lot of 7.3 owners are saying I should have before considering the 6.7. But, I do tow very often (6000 lbs) and often over 75 miles. 2-3 times a week. I put about 35k on my vehicles a year so I think my gas savings will catch up to the fuel cost rather quickly. I will also use it for a daily driver but work is 20+ miles one way and all interstate....once again it pointed to the diesel. Also mentioned was "if you drive the diesel you will want it" I drove it and wanted it....hell I don't have to have a 300 Racing engine on the back of my boat but the power is a rush. Same with the 6.7 that will be in my driveway in a couple weeks. It was really night and day between the two. Plus I will not need to mod anything or throw the warranty out the window to get the power. I also got the 5 year maintenance plan that will pay for itself and the upgraded 100k B to B, so know the engine is Fords worries. I could care less about shoe size, it is what I want and don't need anyones permission to get.....well my lovely wife will get a vote....lol. Cheers and enjoy what ever you justify for yourself to buy!!!! No Regrets!!!!!

When it comes to speedy trucks the TRX is currently untouchable

Not sure how you got that from my post.

I specifically said if its what you want just own it and say its what i wanted.

Could care less about how you spend your money, just dont try to convince us it was smart when we all know it wasnt LOL

I'm a guy that pulls a 36 foot travel trailer that weighs about 7,000 lbs. all over the country. Currently do it in a 5.3L Suburban with the tow package and self leveling rear suspension. Yeah it does the job, but when that asshole doesn't know how to merge onto an expressway and I have to hit the brakes, I end up taking 2 miles to get back up to speed. Headwinds turn fuel millage to a whopping 5 mpg and any incline makes it rev to about 4,000 on the tach. As for maintenance, I've had to replace the torque converter, both axles and the suspension. Suspension wasn't under warranty so that was close to 5 grand.

Yeah a 7.3 would be a great improvement but I want an absolute pulling machine that will not even know it's even hooked up to the trailer. Not to mention the extra power when I don't have a trailer on it. That's why I ordered the 6.7, Is it overkill? Probably, but I don't care. Buy the way, does anyone know where I can find those ball sack things I can hang on my hitch?? LOL!

You will still notice the trailer back there no matter which engine you choose with the large surface area of a TT, but not going to be as noticeable as your old Suburban, will almost feel like nothing after that experience. I thought my 2500 Burb with the 8.1L was a tad on the light side for the larger TTs, the Tremor is giant improvement. I have the 7.3L personally and on occasion get to dive 6.7L duly for work. Definitely notice when pulling a higher profile trailer in the work truck with the 6.7L. The work trailer is a 14ft cargo at just over 7K loaded, yes the 6.7L and will shift down in the wind or big hills just not even close to as much shifting as the gas will do. Comparing the two the the 6.7L definitely feels more powerful but is to the point where it struggles to get good traction in my opinion when really getting on it empty. Nothing wrong with either choice just don’t want to build higher expectations than what they will actually be like.

Platform is a big part of towing performance as well. These trucks handle loads far better than any half ton can or could. At 7k that’s pretty much maxed out on a half ton where as on these trucks that almost 50% right there. Plus figure in gear ratios and power bands, a 7.3 will pull far better than a 5.3 suburban and the 6.7 will be a monster. Just saying it’s not all engine there are multiple factors that make up a good tow vehicle. Towing across the country though the 6.7 might be the better choice though, will be a nice truck.

 

[TexanTremor]

And lost warranty and now have to buy fuel that costs more than diesel.

Yeah, you do lose your warranty. It says they are working on a low octane version. It will be interesting to see how that turns out. As far as the warranty goes, a new crate 7.3 is less than some fuel system repairs on the 6.7! There is give and take to both choices, but both are great engines.

Come on man, forget the engine choice, buying a $70-$90k Tremor in the first place is not a sound choice, we're all "silly" for buying the truck to begin with, including me and you. Everyone here, bought a Tremor because they wanted one, not needed one. The engine choice is no different.

Drive them both and pick the one that makes you smile the biggest smile.

I personally purchased a diesel, because I use it for what it was intended for, but to call a person silly for buying what they want is the only "silly" thing I've seen on this site so far. I guarantee plenty of people believe it's "silly" to by the very first year production model of any vehicle, but hey to each his own. Tremors are not a NEED. they are a want. so I guess we're all "silly".

Shhhh! My wife might read this forum! IT WAS A NEED!

 

[mworkman80]

I didn't know I wanted a Tremor until I saw it. I didn't know I NEEDED a Tremor until I drove it. Luckily the wife was sold on it too!

HaHaHa! Mine has no clue that I've ordered one! ?

It's been nice knowing y'all!

You are saying EXACTLY What I said!

The only thing silly is trying to say you need a diesel to drive to the mall.

If you want it, absolutely buy it!

The whole point was some of the 6.7 guys who never tow, trying to say it was a better choice just because...

The only thing that makes it a better choice was if it made the owner happier.

who gives a fuck? Buy what you want and let other's buy what they want.

I didn't know I had to justify my diesel to anyone.

I went diesel for 2 reasons 1) I've wanted a diesel truck forever and 2) we're looking at large TTs or 5ers and I want the fuel economy and extra torque that the power stroke offers.

Also, not a major reason but it's also got to serve as a daily driver to commute 60 miles a day and I'm all set with getting like 11mpg on the gasser especially with CA gas prices.
