My little blue Scion xD turned two years old on Friday; I took delivery of the car on July 23 of 2008. I filled the tank this evening. It was my 58th fill-up since July 24 of last year, which makes this a good time to look at a bit of data.
I drove 16,700 miles between July 24 of 2009 and July 24 of this year. That's a bit more than the first year. I averaged almost 288 miles per tank, less than in year one. I used more gas -- 519.8 gallons -- and averaged 8.96 gallons per fill-up.
That gas cost me $1,349, an average of $23.27 per tank. Gas cost less in year two than in year one, though, when I averaged more than $30 per tank.
I averaged 32.13 miles per gallon over the year. That's a bit less than my years one average (32.19) and less than my two-year average of 32.2 mpg.
