Really? The 6.0 uses about 20% less fuel than the V10, however diesel can easily average 10% more at the pump, sometimes more in the winter. That puts the V10 at about a 10% fuel cost / mile disadvantage compared to the diesel, which would probably end up being $0.03-$0.04 extra fuel cost per mile. It would take 100,000 miles to recoup the cost of a single FICM failure which takes out the injectors. Or an single oil cooler/egr cooler failure.
Paying for oil changes, the V10 (assuming $30 oil change every 7500 as recommended) costs $0.004/mile. The 6.0 diesel (assuming a $100 oil change every 3,000 miles as most mechanics recommended to prevent HPOP failure) costs $0.033/mile.
Last I checked residual values for fleet leasing, the V10 had a slightly better residual value (%) than the diesel. But yes, since the initially cost is more, the diesel will still carry an outright $ premium after 24-months. Recently, I have looked into higher-milage cutaways. After 100,000 miles (5-6 year old), the V10 carries $ premium over the diesel.
