Why not say 5mpg for the gasser and 17mpg for the diesel. I get 8.5~ mpg with the gassers and 10.5~mpg with the diesels towing over the same routes at the same speeds.
For the cost of a ticking fuel injection system on a newer diesel, I can toss in a new long block and transmission so the cost savings is a gamble in the long run. The 100k mile warranty goes poof at around four years with me.
Not to forget the cost of DEF, fuel filters and special fuel conditioners for the delicate HPFP.
I haven't been banned from buying my 7th diesel. As it is, the only real practical benefit I see is 30% lower rpm. And that's only if you're erroneously afraid of a gas engine running in it's normal rpm range. 3800rpm is peak torque rpm with my wheezing 5.4L grocery getter. It can run there all day under load if it ever needs to without worry. As it is, it's only an occasional sprint at that rpm. On flat ground we run 2k rpm in O/D and 2600~rpm against any breeze or slight incline. Not a problem.:B
Why do people gear their diesels like a gasser so it'll run like a diesel? Why not a 3.08 rear ratio to put it at it's 1600rpm torque peak?
Hannibal I put a lot of weight in your responses because you have been there, done that with diesel AND gas...your input can't be tossed aside with a simple "if you towed with a diesel you'd understand" dismissal.
I should be more patient. I remember my first diesel. Then my first Cummins diesel. I understood 100%. I bored family and friends to tears with how wonderful it was. Once the novelty wore off, it was just a noisy engine that couldn't rev. Now they're prohibitively expensive to buy and repair. The love is still there but not enough to overcome the ticking.
I'm hurt that no one wants to answer my question.:B
