That is about .70 cents more than I can buy gas.

20 mpg gas cost .135 cents per mile (2.70 gas).

Diesel has to get 25.18 mpg to break even on the fuel cost. That doesn' t count any savings toward the diesel engine cost. If you get 27 mpg and the net additional upfront cost for the engine is $2850 then you need to save 838 gallons of fuel. With a mpg differential of 1.82 mpg it will take 242 miles to save a gallon. It will take 202796 miles to break even on the upfront cost of the motor. (I think I did that right).

There might be some operating cost savings or some other performance issues but it stills looks like a gimmick to me. No real cost advantage at all.

Buying an "ecodiesel" to save fuel does not equate to saving money.
