The initial cost difference for a diesel engine is huge. Add in the cost of DEF and those 4-5 GALLON oil changes and oil filter that cost TRIPLE a standard oil filter and that is a LOT of $$$.

Unless you drive 50K+/year AND tow/haul heavy loads, anyone shopping for a new truck should consider a Ford Super Duty with the 7.3L gas and 10 speed transmission.

So what are the numbers? Calculate initial cost, total fuel costs, DEF costs, maintenance, taxes, registration, interest rates, and resale trade in after 100k miles. I did, and came out ahead with my Ram 2500 Cummins over the 6.4L 2500 using both 87 octane and the higher 89 octane that was recommended. The total cost on the 5.7L was lower though.




So what are your numbers? I don't know about you, but I would gladly pay for a more powerful engine upgrade if it only cost less than $1,500 over the course of 5 years/100k. Many pay more than that on engine upgrades in half tons.

Incomplete at best. You don't have insurance, repairs, depreciation, cost of money, ... just to name a few. You don't even accurately reflect the $10,000.00+ increase in initial cost of the diesel vs. gas to start with.
