^^ lol er...thanks?
ryude how are you getting that conclusion? If say he gets 40mpg on the highway portion of his commute (let's say this is most of the 90 miles) with the manual, and 10% better with the auto, he'd be using 2.2 gallons of gas for the manual vs. 2.05 gallons for the auto. 0.15 gallons * say, 300 days, is 45 gallons of gas, which at 4 dollars a gallon is 180 dollars a year. I'm predicting better than 40mpg (at 60-70mph), and I may be overestimating gas price so let's say 160 dollars. 6 years to pay off the auto, assuming he ONLY drives on the highway. In the city, he may not necessarily lose mpg if he avoids using 1st gear past getting the car rolling. The auto box also needs to power its hydraulic pump, which would sap some amount of energy too.
