Saturday, I ended up filling up both our cars with gas. Needless to say, the Prius demolished the Highlander in mpg and cost/mile. The chart below illustrates how fuel efficient vehicles can really reduce our dependence on foreign oil.
Gallons Miles Total Cost Cost/Mile MPG
Prius 7.14 316 $13.92 $0.04 44.26
Highlander 14.2 276 $27.69 $0.10 19.44
