Cost of waste solvent is 0 at this point and time. I pick it up for free while doing paint delivery's to the Auto Body Shop.
Cost of pump fuel is $2.59
6 gallons pump fuel * $2.59 = $15.54 cost for 6 gallons pump fuel.
$15.54 / 12 gallons pump and waste solvent = $1.29 gallon based on 6 pump and 6 waste solvent.
$1.29 / 500 miles driven =.0026 cents per mile.
I think this is right???

Looks right.
There is the argument that it doesn't get 60mpg (guessing here, I don't feel like searching) because you're burning waste solvent. Gallons of waste solvent.
But there is also the argument that the solvent is free. If, for example you managed to figure out how to make the motor run on a 50/50 ratio of pond water/gas would you have to factor the pond water in? I wouldn't think so, you don't have to pay for it.
At the end of the day it comes down to $$$/mi. And you're doing really well with that.
