So the diesel with the better millage save 137 gals of fuel over gas towing.
Diesel can go longer between oil changes.
More than pays for the difference in services cost between gas and diesel that are about 40% more than gas. And that is the rest of the story...
Fuel filters every second oil change.
2 of them. Avg $150.
Also, don't forget the $10k in injectors, when yours go south. ( from you doubling the oil change interval)
Or the high pressure fuel pump.
That's about 4 grand.
Dpf filter.. 3k.
I could do a whole crate engine with my v10 for about 5 grand.
Don't get me wrong. If I could justify always have a diesel under warranty, I would have it in a second.
Till then, I'll stick with my 6.8L V10.
