A diesel tech on another forum says as long as you don't tune a 6.0 and take care of it, it's a good engine.
If you put in studs and a few other things he says they're great.

He also says the Fords and Chevys are what keeps money in his pocket as he doesn't see many Cummins...

You just proved the point about the 6.0. Unless YOU add studs and a few other things ($$$).... Hell, the 6.5 TD also had the potential to be a great engine to with some "extra" work.

Optimiser 6500) 6.5's are actually pretty good.

Why get 3 or 4 hundred thousand miles on diesel engines and lost the trans at 2 hundred thousand miles on all model's, sometimes $15,000 to fix.

He's full of it! I watched not one, but FIVE 6.0's (100% stock, three of them DEtuned van engines) sour two companies on Fords! Ford sunk more than $30,000 each into three different vehicles in a (vain) attempt to keep them on the road! One van was dumped (the other two were kept and are used on short runs, CEL's on and engines sputtering and smoking), both F-450's had total engine failures (one catastrophic, throwing a rod on the highway) and were repowered with Cummins 5.9's.

Years ago diesel was $.50 cheaper than gas, diesel engines were mostly mechanical and ran forever with few repairs, had pretty good power and got great mileage. At the same time gas engines were struggling to meet ever onerous EPA emissions and got lousy gas mileage. Today gas engines are more fuel efficient and also make good power, diesel costs $.75 more than gas and modern diesels with high pressure common rail fuel systems are very fragile and extremely expensive to repair when they break. I've heard if you get any water in the system you're looking at $10,000 + to fix it. If you look at the added upfront expense of a diesel engine, the slightly better fuel mileage will never recoup the upfront cost, and this doesn't even consider the higher maintenance cost of oil & filter changes, urea, diesel additives to try to save the HPCR pump, etc. I currently have an old Dodge with a Cummins diesel and when it wears out, I'll go back to gas burners.
