V10 performance questions
If you are comparing the V10 to the current diesel offered by Ford you will find about 2 to 5 mpg less on the V10 on average depending on how you drive, if you tow etc.
I've been told the V10 has an excellent repair history and is a very durable motor good for 200K plus with proper maint. and use.
The diesels will cost more to maintain. More things to go wrong. Frequent expensive oil changes etc.
I don't know about the newer diesels but I've talked to owners of the older 7.3 that have in excess of 300k on them and are still strong.
All of my info is anecdotal. I haven't owned either motor, but have driven both. I've been researching your same questions for the past year as I move toward owning an SMB. I will buy a V10 for one reason.....noise. The diesels are loved by their owners for many reasons...all valid. I just can't handle the noise.
