Gasoline Costs

One of the nice things about using personal financial software (I use MS Money) is that you can very quickly break down where your money is going. Here's my expenditures for gasoline, not counting vacations or business travel (I use different categories for those), over the last eight years. One note, I have a company car that I use for commuting to work, and the company pays for the gas. In the summer of 2005, I left El Paso for Enbridge, and returned in November of 2007. I didn't really think that having a company car helped with my gasoline bill much, since I only live 8 miles from work. I calculate that my commute contributes about $400/year, but from the graph it appears that there is a larger contribution than I thought. I do drive to the airport 20 or 30 times a year, that contributes another $300 or $350 per year. Maybe I'm getting a better deal than I thought? For once?
