Not a diesel guy, but seems to me when comparing diesel to gas in regards only to mpg, you have to include not only the price of the fuel, but the cost of DEF for the new engines. Cost of ongoing maintenance is a different discussion, but one worth having.
Def costs me about $10 for each 6-7K miles, a whole $0.002/mile, yes .2cents/mile. Heck tires cost roughly 10x that/mile!
As far as maintenance costs, other than oil filter changes, air filter etc. that is normal maintenance, my 04.5 has cost me $0.00 in other maintenance in 190K miles. Neighbors also have diesels, again, zip costs other than normal maintenance in over 200K miles on the current 2014 for or old 7.3. (other than tranny issues on the old 7.3 but that is no longer an issue).
ok, the diesel needs 10qts oil instead of 6, (well, each of my cars take 8.5qts) but no plugs every 100K, and yup an extra battery, a whole extra $75 every 5-10 years.
Those who say diesels are higher maint. costs are usually those who don't have a diesel.
true, the fuel cost/gallon is no longer in favor of diesel, at least in winter. But for mileage diesel wins. Heck, my 2015.5 duramax running 5 over the limit from Portland to central montana averages consistently 19mpg. non towing.
So, IMHO decide on diesel vs. gas based on what you want, ignore differences in maint. costs, they are in the noise.
