As much as I love my truck, wanting diesel I can't get out of my head. One reason is that I commute 65 miles a day round trip to work so I lease a honda accord to drive back and forth to work as it pays for itself instead of putting all that fuel in my gas 350. Looking to get a '14 king ranch or lariat diesel and trade (or sell) my truck and car as I am tired of paying the expenses of having two vehicles. I see most people getting close to 20mpg's on the highway with the 6.7 so that would put me in the middle of my truck @11-12 and my car @30-32. I tow a 9000lb jayco travel trailer and sometime down the road look to upgrade to one of their 5th wheel trailers. If I have never owned a diesel before it may not be on my mind as bad plus I like driving in my truck over my car any day.

 

I know a few rvers that we travel with and the others we see often that has 6.7 and I have never had any of them claim 20 empty, 17 maybe 18 but that's the highest on a good day. Remember there's a difference between posting something on the net and talking to someone face to face.

I had a 2011 F250 diesel 4x4 CCSB before my current 2014 F350 4x4 CCSB. I saw 20 a couple of times empty, but mostly saw 16-17 and my overall average was 15.3 combined mostly highway occasional tow. My average towing was 11. My current avg with this one no towing is 13.

 

I don't know about the 6.7 but when I had my 7.3 it would get about 18 mpg empty at 65 mph or less. At 70 mph I would lose 2-3 mpg. Once the ULS fuel came out with the higher price I didn't see any savings over gas. Granted, if you tow a lot a diesel might be better.

 

Mpg is important if I get rid of my car too. If I kept my gas truck as my daily driver, putting @ 20-24k miles a year on it would rapidly decrease the value and spend an average 400-450 per month in fuel but with the diesel they seem to hold their value as the mileage get higher which seems you regain some of the upfront cost of buying the diesel. It would be a whole lot easier if I lived 5-10 mile from my work.

 

the 6.7 is not designed to be a mall crawler - it is a work engine - likes to and needs to be worked. Commuting back and forth to work is not going to make it work. Do a little research - several people have broken down all of the costs - original purchase price - operating cost - in my part of New Jersey diesel fuel is between .35 & .50 cents per gallon more than regular gas. Maintenance costs etc.

Bottom line - weather it makes sense or not - if you want a diesel truck - then get it - otherwise you will not be happy. Been there done that - everything does not have to make sense or be practical - do what puts a smile on ya face !

 

DJM1204 said it really good.....buy what you want....

I have gone over this back and forth a million times.....I really like the 6.7 but it makes zero sense to own one for my purposes and I really love my 6.2 and I am not so unhappy with it to sell or trade and take a hit for a 6.7 plus buying a 6.7 and forking out that almost $9k price tag for an engine I don't need is a waste for me.....I got 2 other cars in the garage that could benefit from that money.

If you try to rationalize a 6.7 for mpg for your uses.....well you are wasting your time. By the time you add the initial cost, maintenance and higher fuel cost, you would have to drive that thing a long time to just break even!

I have done the math....the difference between a 6.2 and a 6.7 is about $.03-.05cents per mile. and that does not factor in the initial hit.

With all that said buy a 6.7 if you want...they are bad ***

 

It's bad *** enough that they call it The Scorpion!
Buy it!

 

If you got the money, give it to Ford. Keeping what you have will be cheaper in the long run. Doesn't sound like you use the truck enough to get the value out of a diesel. Last week I saw a Good Sam State guy with a ford dually 2wd and 5.4 gas pulling a 5th wheel that was probably 38ft long and said he didin't have a problem. Dave

 

I moved up to a 6.7 diesel from a 6.2 gas. I'm very happy with the change. My 6.2L would need to be nursed to get 15mpg on the highway at 100km/h, the 6.7L has gotten 22mpg on the highway at 100km/h a few times. There will be naysayers and "haters" (I dislike that word), but I hand calculate each and every tank using the imperial measurements and this is what it is. Since buying the diesel this past December, my lowest recorded consumption was 13mpg. You will not be disappointed in the change...

As for taking a long time to recoupe the added costs of buying a diesel, you'll break even in 3 years or so as I've figured. Also in my research, the diesel depreciation is usually less than that on gas vehicles...

I'm not taking away from the 6.2L show at all, it does exactly what its intended to also!!!

 

Traded it in on Wednesday, and all I can say is wow!! I have almost 500 miles on it and getting 18-20 mpgs and power is almost night and day. Don't get me wrong the 6.2L in a capable engine but the diesel is a beast.

 

Nice truck! I've been watching your thread and all the comments and was hoping you would stick with the 6.2L. I'm battling the same thing in my head. I have a 2013 that I got below invoice so I don't think it would take a huge hit if I traded it in. My heart wants the diesel but my brain says to stick with the gasser. Congrats on your new ride!

 

I am glad I made the switch. I really wanted a diesel when I bought the 6.2 but everyone talk me out of it saying I didn't need a diesel. If I had a smaller camper and only drove about 10-15 miles to work it would have been fine. With that said unless I have a lot of trouble with it, I will alway have one.

 

That's my issue. I drive 5 miles to work but we tow about 4,000-5,000 miles a yea. Lotsa steep grades out here and we are thinking of upgrading to a fiver which will be around 10k wet. I'm happy for you and jealous! Time to start working on the wife!

 

I've been thinking the same thing lately. I like my 2013 6.2, but after I test drove a 6.7 recently, I'm thinking about trading also.
