As the title states. Any regrets making the switch from the 6.7 diesel to 7.3 gas? It has been out for 5 model years to date. Approximately how many miles do you have pulling your trailers with the 7.3? How heavy are your trailers? If you have regrets and switched back to diesel you can be truthful. There will be no hard feelings whatsoever. Going from diesel to gas is not for everyone. We are not comparing the 6.2 which is not any comparison to the 7.3 powerwise. I used to own one for almost 5 yrs pulling our 12k fifth wheel for 13k miles. It did well considering and it had the 4.30s but it is a dog compared to my 7.3. If you still own the proven 6.2, you can post as well.

 

I sold the 2017 6.7 CCLB and recently bought a 2024 7.3 CCSB Lariat Ultimate, Tremor, Sport with 4.30's no regrets it's a beast.

The main reasons I got rid of the 6.7 are...

1. The potential for insanely expensive cab off repairs.
2. Warranty denials based on 'bad fuel' BS. Been through that once already with Ram (I won)
3. The long bed was too much of a hassle for a daily driver.
4. The Ford seats were stupidly flat and hard, not comfortable on a longer trip. These 2024 seats wow night and day difference.
5. Diesel emissions BS, soot cooker etc. excluded in extended warranty.
6. Annoying regens and DEF hassle.

The 7.3 talk about pushing my buttons. 445cu check! Cast iron block, forged crank, 4 bolt mains check! Good old fashion pushrod valvetrain check! Godzilla really that's it's name? Check! lol I grew up working on this type of engine. It can be rebuilt. The design goal was reliability, ease of maintenance, lower cost of maintenance, can be rebored/rebuilt. Plenty of power, it looks like they underrated it based on some dyno results of the stock engine.

Yeah the gas mileage is not great, but hell my Ram 1500 5.7 was only getting 13-14 around town. I'm within 1-2mpg of that with the 7.3 so far if I deep my foot out of it. If you do the math on the added cost of the 6.7 that's another $10k to $12.5k and that's before the more expensive maintenance and DEF. That buys a lot of gas.

I'd only go back to a 6.7 if I had no choice, if it was required for towing whatever I was towing.

 

I don't know but something tells me this thread could slip down a slippery slope. We'll see. 🤔

 

I only regret not doing it sooner. I have 13 trucks active right now in the company. Saving money and time not dealing with diesel issues.

2024 F650 7.3L/6R140 GVWR 25,999lbs - primary designation is dump truck but tows up to 6 ton machine when needed.
2024 F600 7.3L/10R140 GVWR 22,000lbs - primary designation is dump truck but tows up to 8 ton machine when needed.
2024 F600 7.3L/10R140 GVWR 22,000lbs - primary designation is dump truck but tows up to 8 ton machine when needed.
2021 F600 7.3L/10R140 GVWR 22,000lbs - dump truck only.

No complaints from the crew and all trucks keep up the work day pace same as the diesels I had in the fleet. All the praise on cold mornings for the instant heat and no cold start issues.

 

I'm not trying to let it get that way. That's why I said be truthful about it. Even if someone switched back, hey there is no harm no foul. Again, a gasser is not for everyone that is for sure.

 

I went from a Chevrolet Silverado 6.5 turbo diesel 4 speed to my "New", 3 years old now 6.2 gas with the 10 speed... WOW, I just love this truck, hands down the winner in every category, even in MPG it's almost as good, "probably better" when you add the DEF & maintenance costs... Now I only use it to haul my slide-In camper, but it seems to me that it is doing a much better job than the Chevy did... I know the Chevy diesel is not a 6.7 but my son has one and having driven his truck, I would still choose the 6.2...

 

Sounds like you have been down the gasser route before. The only thing I dont like about my gasser besides burning a lot of it is that finding a gas station that has enough room to maneuver the 36' fifth wheel to the pump. For the past 5 yrs I have been used to it. If the Godzilla gets 250k miles or more on them on average without them being opened up, Ford has really hit a homerun on that engine. Plus it sounds awesome. Like you said it is a very well built engine. I didn't think any of the Big 3 would ever come back out with an old school pushrod engine.

Have you had any problems out of your 6.7??

In my opinion, the reason why a lot of people went with a 6.7 from the 2011-2019 model years is because there was only 1 gas option which was the 6.2 which is a very stout engine and proven, but it didn't have the torque if you wanted to tow heavier, So a lot of people opted for the 6.7 at the time which they sold like hotcakes back then. Ford usually has 2 gas engine options, but they didn't at the time which I didn't understand. Now currently they have the 6.8 minizilla and the 7.3 Godzilla which could take a few sales from the 6.7 but not a lot. There are still a lot of diehard diesel fans out there who fully swear by them which is nothing wrong with that. You only live once, and it's only money 💰 like they say. Life is short, so buy what you want if it makes you happy.

 

That's good. Saving time, is saving money!!! The less downtime, better. I never knew that they made a 6r140 and the 7.3 combo which a very bulletproof combo. I thought all 7.3s had the 10r140s but I guess they don't.

I guess time will tell longterm on how those gasser will treat you. It hasn't been that long since those trucks are still newer, but it looks like it is working out well for the company. Also it makes for less downtime too. Worst case scenario for the gasser is that the motor could go bad, and you can drop in a long block for the same amount or cheaper than a diesel component(s)going bad which could make for longer downtime. Could be weeks or months and maybe a part has to be special ordered or backordered. You never know.

 

Wow, I haven't heard about the GM 6.5 in years. They did not get good reputation at all back then. At least it didn't have the new emissions BS. Sounds like yours still ran good until you got the 6.2. I remember they made the 6.5 non turbo diesel. You will love that 6.2. Enjoy it!!

 

Ehhh, at this point im still in the corner of the old 6.8 V10 that the 7.3L replaced. Already lost a 7.3L engine at 30k miles in the 2021 F600. We will see the long term but its already left a bad taste with me.

As for the 6R140 equipped 7.3L, they are available in all of E series, F series stripped chassis, and medium duty F series. Im sort of split both ways. I love the performance of the 10spd but cant argue the reliability of the 6spd. Im not noticing the extra power of the 7.3L compared to the V10 6.8L with the same 6R140 and 6.50 rear end in both of my F650s. Id have liked to get the F650 with the 10spd to better take advantage of the small bump in engine power between the two.

 

Zero problems with my 6.7 and it was a torque monster. I consider most of the modern gas engines of the past 20+ years use and throw away. Aluminum blocks with sleeves or spray on liners not really designed to last or be rebuilt. Certainly the Ram 5.7's don't last. Hence the 7.3 got my attention. Both my brothers owned diesel trucks before the government emissions crap wrecked things. I'd own one of those vs a 7.3 for sure. But what used to be almost bullet proof diesel engines are now rather prone to failure and very costly to repair plus now get significantly worse mileage.

 

I went from a 6.7L Cummins to the 6.2L/6R140 after the Cummins left me stranded with emissions issues. Sure there was a noticeable difference in towing power, but the 6.2 held any speed limit with 12k behind it here in the Appalachians. Now I’m in a 7.3/10spd and it’s a huge bump in performance…I dare say very close if not equal to my past Cummins. I’m extremely happy switching back.

 

That is awesome that you didn't have any problems out of the 6.7. I assuming that you got rid of it before it could start taking you to the cleaners financially. You got lucky. Yes I totally agree with you on the government tampering with the newer diesels and ruining them. It sucks. They don't make things as good as they used to. The older pre DEF diesels are the way to go. Much less problems.

 

Absolutely nailed it.

I was searching hard for a 7.3 truck for all the reasons listed here. Unfortunately, the 7.3 trucks were very hard to find when I was shopping. Only found one in a 50 mile radius and it was priced too high. So I went wtih a 6.7 diesel because they are so plentiful. I do love my 6.7 and it pulls like a train. But if I was ordering a new truck it wouldn't even be a consideration.

Side note: my best buddy has a 28 foot camper and a 2017 F-250 with 6.2 gas motor dedicated to pulling it and he's got 170k miles now. He loves it. It's been a work horse with no big repairs.

 

Except for numbers 3 and 4, I went to the 7.3 for the same reasons. I'll add that I opted for the 6.7 in my 2017 F250 KR simply because I wanted to try one. And while I enjoyed the gobs of power, I didn't need it. Heck, I don't "need" this F250 2022 KR but opted for the 7.3 because its trade-in value later on should be higher than the 6.2. And even though I only drive it about 4K miles/year, fuel costs less, too.
