So, this blog is well out of date, but I once again think of reviving it. First, though, I have some data that I really want to share with everyone. Really. Everyone.
Being me, I have been tracking the mileage and costs associated with my Prius pretty much since I bought it about three years ago. I don't have any data for the first 4000 miles, but I noticed that what I calculated to be the miles per gallon based on the odometer and gas pump was different than what the on board computer calculated. So, I created a spreadsheet (I wonder how many great ideas start with these words . . .).
In that spreadsheet I tracked each tank of gas, my mileage, my costs along with comparisons to my previous vehicle - a Kia Sedona. The Sedona was a fine minivan, but it got maybe 16 mpg and at the time of my purchase it was more like 12 mpg because it was right after Katrina, I live an Baton Rouge and commute to Lafayette. Gas prices were skyrocketing, I started commuting 130 miles per day, so goodbye minivan, hello hybrid.
Enjoy the charts. Note the drop-off in mileage in the summer of 2007. That is a new set of tires. I lost about 5 mpg with the new tires, but everyone denies that it is related. The data says so and no one offers an alternative explanation. So there. QED.
