There is a general trend among the automakers to "hide the ball" --- some aren't even releasing monthly sales figures anymore and Ford sure as hell isn't going to release data its competitors can use against it. Consumer reports does a "parametric" analysis of reliability and from a statistics / operations research point of view the data isn't half bad. Ward's does "awards" for best engines but they've made some hideous blunders over the years (e.g. 5.4L was chosen as "best engine" before Ward's realized the spark plugs were blowing out, going into "orbit" ).

The Made In Mexico 6.7L engine has shown improved reliability over its lifetime, but it's a maintenance hog and in the views of my guys (most ASE Master Techs), one of the worst engine layouts of any we work on.

Diesel fuel prices generally are at artificially low levels due to the fact fracking (hydraulic fracturing) is good at producing middle distillates (jet fuel, diesel), not so good at light distillates (gas). The US is "draining the wells" fracking and in about 5-10 years diesel prices are poised to explode and fleets will be looking at alternative fuels.....................same holds true for retail buyers.

 

Do you happen to know the B50 rating?

 

I'm not familiar with the rating scale, can you explain!!

 

This isn't really a sunk cost though, since you get on average $9-10k more for a used diesel. So you park some money in your truck for a while and you get 945 lbs of torque while you do. Then you get it back on the outset. Its really not that much more to maintain a diesel either. Maybe several hundred to $1,000 over the lifetime. Pennies on a $70k truck. The money thing really scares some guys, and maybe its not for them. But in the entirety of owning the truck, you don't come out much lighter having owned a diesel for all those years. The diesel also has a 100k mile warranty whereas the 6.2L has a 60k warranty. So if you are putting a lot of miles on it quick that might be a big factor.

 

One train of thought is to trade near 100k miles and not worry about the rest!! That's my buddy's plan.

 

B10 & B50 Life of Diesel Engines

B10 is saying statistically 10% will need major component work in the mileage.
B50 is saying statistically 50% will need major component work in the mileage.

 

^^ what he said, basically 10% will need an overhaul on the motor at 250k.

 

thanks. I wish the emissions components were rated also!!!

 

Or buy a 150,000 mile Ford ESP and never worry about it.

 

 

It seems like very week there is another thread like this.

Should I buy a diesel or gas...

The gasser advocates tell you there is no justification for buying diesel. Gas is cheaper, more reliable, easier to live with and will pull (almost) whatever you want it to. This isn't untrue.

The diesel guys (I own a '17 6.7) will tell you reliability is acceptable, diesel's hold their resale value, cost of ownership isn't that much more and the power is unparalleled. None of this is untrue either.

It all comes down to what you want and can afford. Drive both and buy the one you want (assuming its within your budget). I am a business owner and understand overhead and costs. If I were to make a business case to justify my buying a 6.7 over a 6.2 I couldn't do it. The 6.2 will pull my trailer adequately. Will have an adequate service life. Will have somewhat lower operating costs (marginally). Oil changes cost 3X what a gas motor does. Fuel filters are an additional cost but $50 every 15K miles isn't a big deal.

I have owned a 7.3 PSD and a 6.0 PSD. The 7.3 was a timex watch. It took a licking and kept on ticking. As reliable a diesel as you would find anywhere with adequate performance. The 6.0 and 6.4 are the horror stories of the diesel world but even then their problems are manageable. My 6.0 PSD was a great motor once I understood its service needs. I would have been happy enough to have bought another to replace my '07 F350 after 10 years of service.

The 6.7 has proven itself to be a very reliable and durable engine and really only has a single significant vulnerability; the fuel pump failure. This is a known issue and can be dealt with effectively. These failures are linked to water (or other contaminates) in the fuel. There are measures that can be taken to reduces the potential of this failure (where you buy your fuel and being attentive to draining the separator). Or, install one of the fail safe systems. Other than that there is little history of other problem areas beyond normal issues that can be expected of any mass produced vehicle.

I love my '17 PSD. After driving both a 6.7 and a 6.2 I gladly paid the premium for the 6.7 and would do it again tomorrow. I also bought the ESP as I know that any significant issue encountered, beyond the standard warranty, will more than pay for the cost.

 

Not sure where you are getting your data from, but here is the average prices for all used 2011-2019 F250 Lariat's on AutoTrader.com right now. Its almost exactly the price difference between motors. So, I'll have to disagree with you here and say that you do actually get most of your money back for a diesel. The sentiment here on the forums is that Diesel's don't last anymore a no one is buying used...the market however does not seem to agree. I will tell you that the only reason I didn't go used on my 6.7L was because there was so little price difference between a used 2014-16 diesel and a brand new 2017 it was a no brainer to get brand new. This comes up every time this same argument gets rehashed, a few seem to have your same thoughts, but I'm not sure why.

Diesel: Average: $58,215
Gas: Average: $47,050

 

You are absolutely correct. The diesels hold 100% of their value and even command a premium over a gas. Seen it for many years now. Even the 6.0s are still commanding s hefty price for hold old they are.

 

I did a little bit of checking (after BS mentioned it) and the B10 and B50 ratings of the 6.7 are right inline with the 7.3. Matter of fact the F650/750 have the "derated" version of our motor/trans and have a 5 year 250,000 mile warranty on them with the first two years being unlimited mileage and a B10 of 500,000 miles. Now obviously they are used more toward over-the-road use but it does give some indication of what these engines/trans are capability of. Makes me feel a little better about buying a F550 and keeping it in stock form, to bad the light duty cab and chassis don't have that same warranty.....
