15 Quarts of oil...
All of the newest diesels offered (6.4, 6.7, and 6.9(?) Ford, Dodge and GM respectively, I think) are crap. Over emissions strangled, overpowered, and suck fuel down like it's free.
Thanks for all of the opinions and insight.. It's too bad Ford or Dodge never made something the size of the F150 with a diesel -- large enough to tow big loads but small enough to get really good mileage.
Drove a mid-nineties F250 with a flatbed and a Caterpillar 6-cylinder under the hood. That was pure torque, my friend. All mechanically controlled like the 12v Cummins, but putting it into the truck was simply a matter of sourcing an F450 transmission and engine supports. Caterpillar engines are an option once you climb past the F350.
I WANT ONE!!! Have any photos?Was it a 7 speed trans? I've also seen GM medium size trucks (5 ton?) with a DD. 6v-something I think... Of course some old Fords (L series I think) had 6bts.
