Reg. gas is easily found @ $3.30/gal. Diesel is holding steady @ $4.00/gal

Assumptions:

Diesel option = $4000 + 8.5% sales tax = $4340

DEF consumption = 1.5% by volume of diesel fuel x $7.00/gal (maybe underestimated )

Diesel mpg = 25

Gas mpg = 18

So the comparison is

gas cost/miles travelled

vs

diesel fuel + DEF+$4340 diesel option cost/miles travelled.

The break even point where the diesel becomes more economical to run has moved all the way out to 227,000 miles at roughly $41,600 operating costs.

The 70 cent differential in gas vs diesel is key here. At this point the margin has become so slim that a slight change makes a huge difference.

For instance, is you substitute 19 mpg instead of 18 for the gasser, the break even point more than doubles to 458,000 miles.

If you keep the 18/25 mpg number but increase the price differential to 80 cents, the break even point is 320,000.

Yikes!

So the new questions are,

Will you buy a diesel if you know it will cost you more to operate for a very long time? or forever? Will the commercial market accept a higher total cost of ownership for the diesel rig?

Anybody want to try to predict the future of the differential in Gas vs Diesel prices ?

Does Sergio have a room full of analysts tracking these trends, and has decided to delay the diesel intro, due to economic reasons instead of mechanical reasons ???

We live in interesting times.
