6.7 here. First Super Duty and first diesel and I love the truck.

 

It would be very interesting to have a poll like this but for people who use them for work, as in using them to deliver a profit, period. I didn't read all the posts but from the last couple years I have really noticed that anyone who has to absolutely depend on the truck, and need it to help their bottom line, it is a 6.2. I may be wrong, but it seems like most of the diesels are two types of people, guys using the truck for fun stuff like camping, or they just have to have a big diesel truck because they want it (which is perfectly fine) and anyone who just wants the best for reliability and the bottom line gets gas.

 

All the SRW trucks in our fleet are gas. The DRW 450/550's are diesel.

Downtime is the deal breaker. Diesels aren't reliable.

 

In model year 2011 and newer my company started switching from Chevy/Duramax 4500/5500 to Ford V10 F450/550. The decline in downtime alone pays for the lower Mpgs of the gas trucks.

I cannot vouch for the reliability of the 6.7 powerstrokes, but when I was driving a Duramax I sure was glad I was still getting paid when my truck was down, or I would have been eating an awful lot of soup beans and spam because of that truck.

 

 

6.7L for me, but when the 7.0L comes out and if it actually has some ***** then I'll probably switch back to a gasser. I had a 2015 6.2L and with it empty it was ok but as soon as I put weight behind it, it was gutless turd. But I knew that when I bought the truck.

 

It would be very helpful to forum readers, if the self appointed "experts" on diesel reliability would cite their facts or data supporting statements such as "Diesels aren't reliable"! Did you mean "ALL" diesels, some diesels, just Ford diesels, Freightliners, etc etc etc.? All of the forums I follow, suffer from the same "opinion as fact" posts as FTE. (if it's just an opinion, state it as such) I found the poll interesting, but it would be more interesting to see the "actual" sales percentage data on the millions of Super Duty's sold since 2011 - how statistically close is the forum poll to actual sales.

 

Good comment jbrnigan. The "diesels are unreliable" thing is completely contrary to my experience.

 

If reliability on "diesels" was so bad, our trucking industry would be going to huge gas powered engines!?.

News Alert! Diesels rule on longevity and torque needed for towing. Period, there is no argument to this. Down period on diesels vs. gas is just hog wash. What these guys don't consider is their pansey azzed gas trucks don't get near the abuse, use or miles that the diesels do.

You gas guys should stop being jealous (or whatever it is?) and just enjoy your truck! You have a very nice vehicle, stop trying to justify why you didn't spend the $8 grand more. Who cares, not everyone is the same or has the same needs in a truck.

Mingya facuccia!

 

Wow, you've been on here a Month (I know you have like a jazillion posts already within that time) but don't you think that the 450's and 550's are diesel cause they need the heavier service engine?

Your last sentence was certainly a joke with absolutely zero credibility, but I guess anybody can say anything, right?.

 

I would agree with this line of thinking for diesels built prior to the EPA ruining them with emissions equipment. If they last so long why does everybody either trade them in before the warranty expires or pay for an extended warranty?

 

I'm not surprised how close this poll is. It actually supports what I see in my area very well...a lot of gas trucks.

As has been pointed out, the gas 6.2L is a great motor...even better for 2017+ with lower down torque and more of it. It is not a penalty box to own one.

More and more 450/550 fleet trucks (I'm talking cab and chassis trucks upfitted to be dump trucks, stake bodies, mechanic bodies, utility trucks, flatbed / wreckers, etc) are being sold as gas V10 trucks. I would say this is due to lower buy in cost, lower maintenance cost, and being capable of "getting the job done."

I'm driving a 6.7L right now but I've had 6.2L trucks as well. I use my truck in my landscaping side business to make me and my employees money. As to the comment about people needing to make money with their truck buying gas over diesel, I think the reason why has nothing to do with reliability. It simply has to do with the fact that a gas engine truck is much cheaper, and gets the job done. Sure, towing 15k lbs behind a gas one ton isn't that much fun...the engine is sure straining up hills...but it gets the job done and doesn't break. When it's a work truck nobody cares how fast or smooth the truck is. It just needs to get the job done and not break.

Cold weather performance couldn't be more different between a 7.3L and a 6.7L, or even a 6.0L and and 6.7L. The modern diesel starts basically as well as a gas, even if you don't plug it in. Yeah, I had problems during the last cold snap with fuel gelling up. I had to replace the filters. It was annoying. It turned out all the fuel suppliers in the area didn't count on it getting as cold as it did, and didn't blend enough winter fuel. In my case, my fuel supplier refunded me for the gelled diesel and the filters. But with proper fuel, you won't experience issues. I'm talking about the truck starting and running well at -22F. I have pictures to prove it.

My daily truck certainly tows equipment for my business, but its also my daily driver to and from my primary job in IT, and my vehicle for family / out of town trips, etc. I picked diesel because its more enjoyable to me.

As for reliability, it is an unfair statement to say the 6.7L isn't reliable. It sure is! But there is the potential, no matter how rare, of incurring extremely expensive engine repairs that wouldn't be covered under warranty if you had a problem with your fuel system. It is true that emissions controls have caused these trucks to not do as well on fuel as some of the older diesels did, but they still whup up on a gas fuel economy.

 

How do you spell DEPLORABLES.

 

I spoke with my uncle who has been behind the parts counter at a GMC dealer for 25 years and only drives gas 2500 or 3500 trucks (he buys lightly used trade ins). This was almost the same list I came up with as well. I like the "Do you live in Texas?" part. I was just in Austin TX and I saw no less than 100 6.7L 2017+ Super Duty trucks.

Either gas or diesel (I went gas), these trucks are super sharp and stand out!

 

Just posted this another thread a little bit ago...but it fits here too...

2017 CCLB 6.2 is my daily driver. My driving habits are mostly like this:

Daily:
15 miles round-trip to and from work at an office job.

Occasionally:
Pulling a 6,400 pound (empty weight), about 7,500 (loaded weight) travel trailer about 8-10 times a year for some family camping. Distance ranges from 30 miles to 400 miles one-way.

The long bed can take some getting used to, but the first time you go camping and put 4 kayaks (one 11 footer, one 8 footer and two 6 footers), 3 bikes, a fire pit, firewood, and whatever other miscellaneous gear you can stuff into it, it all makes it worthwhile.

My big concern was the total weight rating and with 4 kids and camping gear, I wanted to make sure there was enough capacity to safely tow and bring everyone with me in the truck instead of taking 2 cars...which is what we had to do with our 2012 Expedition that I moved up from.
