In my experience with a PSD only one i like it was 99 f350 with 7.3L.
670K miles when totaled by SWIFT truck.

We had a 6.0L witch was junk:replaced by ford @37K,99K,175K,280K and when blow up @340 we give up on 6.0L and went to dodge witch we got @440K miles on the original motor and still in service.
Under load 6.0L fuel mileage was ~9mpg,V10 same load 9.7mpg
My 06 V10 was replaced due some idiot stripping the plug thread.(truck was owned by large corporation so they did not care on putting bend new motor in it).I got 334K miles on the chassis now.
If it blows it won't cost me $14K to replace it.

Keep in mine the all the trucks pull 15-19K lbs trailers full time.

I need my trucks to work ,not to sit in the shop like the 6.0 did.time lost while diesel in the shop i take lower MPG and less down time.

In the end V10 vs 6.0 in 5 years of service was cheaper truck to operate.

But if you want to have a big exhaust and turbo wisle go ahead and buy a diesel.


My 0.02.

sounds like the 7.3 gave you your moneys worth.We use to have 2 12v cummins in our fleet and 2 24v cummins along with my chevy 454.The 12v cummins definitely got better mpg but they loved to swap trans more than swingers swap wives.They were reliable though and got about 12-14mpg

The 24 v cummins were absolute******we constantly took one truck to drop off while we picked up the repaired truck,cracked blocks,turbos,injector pumps,etc.oh and these junkers only got about 10mpg all with less than 100k problems started at about 25k miles

All in the mean time my 454 never skipped a beat only downside 9mpg.All these dodges were bought cause the Ahole foreman at the time was a diesel only guy and recomended to boss he go diesel to save.To this day my boss says that was the biggest mistake he now has all gas motor 6.0 chevys but i will say some only have 125k and feel like they are on their last leg too but as far repairs they werent familiar with the repair shops like the diesels were.
