Not yet they don't.

 

OP, I will be the dissenting opinion on the gas vs diesel mantra. Having owned 5 diesels in the last 13 years, I now drive a 2019 F-250 6.2. Why? I am one that has owned a pre emissions diesel and can truly say it's the only way to go if you can find a pre 2010-11. Having said that, you could not give me a new diesel with an EGR, Def fluid, CP4, DPF that will go into limp mode and leave you stranded. My last three trucks ( 2012 and newer) all had issues and they were both Ford and GMC. Call it bad luck but it is what it is. Where I live, emissions testing is every two years so deleting is not an option. Therefore, I had to deal with a DPF that would clog, replaced a DPF, injectors that went bad before 100K miles, lost a turbo due to EGR black tar soot and finally a CP4 the blew and cost a nice $13K to replace the entire fuel system (Duramax). All of these were business vehicles that were used but not abused and I am here to tell you that these issues do happen regardless of what is stated on a truck forum. We can go round and round but operating costs on an oil burner is more expensive especially when we talk about glow plus, EGR's, filters, injectors and fuel pumps. One trip to the dealership for anyone of these issues also makes the resale argument nonsense a wash.

I went back to gas trucks from the standpoint that they are simple and cheaper to operate. Sure I have to worry about a set of spark plugs and an oil change but thats about it for the most part. I also do not have the time to make sure I take the truck on a 30 min trip down the highway once a week to make sure the DPF doesn't cause me issues. From a business standpoint, it is cheaper for me to replace an entire engine than it is to replace a fuel pump that exploded or a set of injectors in a diesel.

Having said this, I miss the power and torque but not the headaches.

 

Agreed. I went with the 6.7L because of the lack of problems I found on the forum.

 

Have you asked this question in the 6.7 section? You’ll get less of the “what if” worse case scenario answers in that section. I dug through that section when I was shopping and I only found a handful of issues actually caused by the engine. Most issues had to do with bad fuel or a faulty sensor. Those aren’t really diesel reliability issues IMO.

I went back and forth when I was going from a 5.0 150 to a 250 and decided on the 6.7 because I was towing through mountain passes once a month. The torque is amazing going up long steep grades and the engine brake is awesome coming down. I was 100% content with my choice. Until I moved. Now it’s totally flat around here and I could easily tow with the 6.2. If it wasn’t paid off, I might consider trading in for the 6.2 because fuel is less and maintenance is cheaper. But I still love the power of this truck!

 

As with most online automotive forums, what you read hear is mostly complaints because it's a rare occasion when someone makes a post saying, "Hey, y'all! My vehicle is running perfect and I've had no issues whatsoever." Most folks use these forums to identify a problem and how to fix it, or they come to hear all the "bad stuff" about a prospective purchase. Forums like this one are also a good source for modification ideas, but again, who starts a thread about a non-issue?

 

Its not that bad. Agree above the EGR sucks, I wouldn't rush out and delete it though. EGR has been tearing up motors forever.

But if reliability is any question and 225k miles is what the OP wants get the 6.2. Unless you need the diesel.

 

I’m on my 3rd new SD. 2000 F350 5.4 auto SC SB, 135,000 km. Only issues were brakes wore out fast, warped rotors, 4.10 axles, still gutless, 4 speed auto was not great either. Wish I could have afforded the diesel in a manual at the time.

2005 F350 6.0 Torqueshift 5 speed 3.73 axle 6 litre. Brakes lasted to 172,000 km, never an engine problem, good fuel, fuel filters, engine oil and filters, all my own maintenance. Couple 4*4 air vacuum valves, vacuum pump, oils and fluids, brakes, rotors, tires, shocks, steering dampers. Wear items only. One FICM because batteries died really cold, had to try and start it, ruined the board on the FICM. Only special thing I did was a coolant filter. Traded at 250,000 km.

2017 F350 Crew LB 6.7 diesel. I’m at 49,000 km. Battery bracket and battery corrosion issues, new tow hooks, chrome rusting, new running boards, new rims, chrome peeling, already on first set of new tires. No issues with anything other than warranty above. I have a 200,000 km extra warranty and full service package to same. These guys are right, once you tow or haul with a diesel, you won’t want to go back. I love this truck so far. I loved my 2005 for 13 years. After driving a diesel, I won’t go back to gas unless I am buying a car and don’t need a truck.

 

If you buy used look for the upper oil pan leak. Crawl under the truck and look about 8 inches forward of the oil pan that you see under the truck and see if it is wet there. This seems to be the most common problem out there for the 6.7.

 

I was concerned about the same thing when I bought mine. Mine gets a good mix of highway and city driving. It does a regen about every 500-600 miles. It has handled everything I've thrown at it with ease. Great trucks.
