Lets see. 8200 trucks now get better gas mileage. Lets assume 12,000 m/year and lets assume that the old trucks got 15 mpg and the new trucks 20 mpg.
Old trucks gas consumption - 8200*12,000/15 = 6.5 million gallons of gas
New trucks gas consumption - 8200*12,000/20 = 4.9 million gallons of gas
Obama has saved the US 1.6 million gallons of gas. At $2.50 per gallon ... that works out to a saving of about $4 million dollars per year.
Now the cost of the program was $4,000 per vehicle so multiply that by 8200 trucks and we get a program cost of $32.8 Million.
So, the boy genius SPENT $32.8 million to SAVE $4 million. That means it will take more than the next 8 years for the economy to see a return on the savings.

The numbers are even worse because as Edmunds has pointed out many of the purchases would have hardened anyway.
Where I come from you have to account for the cost of money and discount for the probability that the expected benefit will be realized. I'm thinking never is a better estimate.
