Cost per mile

2010 Toyota Rav4
Cost per gallon 2.07
Total gallons in tank 15.9
Est. MPG highway 28
Miles traveled on tank 445.2
Cost per mile 0.004649596

2013 Subaru BRZ
Cost per gallon 2.7
Total gallons in tank 13.2
Est. MPG highway 30
Miles traveled on tank 477
Cost per mile 0.005660377

Slow day at work today, and I wanted to figure out the cost per mile for my 2013 BRZ vs my wifes 2010 RAV4 (2.5L I4)

Gas in Charlotte, NC for Regular is around 2.07 (gasbuddy.com), Premium is 2.70 on average
I know that all the 15.9 or 13.2 gallons of the tank are not usable, but for the sake of easy comparison I used the full tank capacity for both.

I looked at the estimated MPG for each, even though I know we both get better than that when driving(especially on the highway, I have gotten close to 38 before on long roadtrips with MT)

Anyways, I took a perfect situation when you could consume every last ounce of gas in the tank, and multiplied that by the estimated MPG, to get the total miles per tank possible. Divide that by the cost per gallon, to get these numbers.

Thoughts? Did I totally screw up my logic in how to do the math?
