Gas statistics

Well, I finally completed one of my todos. When I purchased my beast, I started keeping the gas station receipts. And, today, I completed entering the data into XML format. After that was accomplished, I wrote a Python program to perform some rudimentary data analysis. And this is what I found:

Total Mileage Driven : 15712.7
Total Gallons Consumed : 1178.019
Total Cost : $2162.67

Cheapest Price per Gallon : $1.399 on 12/03/2003
Most Expensive Price per Gallon : $2.349 on 04/06/2005

Best Miles per Gallon : 15.362
Average Miles per Gallon : 13.338
Worst Miles per Gallon : 11.605

Lowest Total Paid At The Pump : $18.59 on 06/02/2004
Most Expensive Total Paid At The Pump : $43.22 on 03/10/2005

I have always suspected that the beast guzzles fuel and 13.338 Miles/Gallon confirms it. What was surprising was that fuel prices have risen one dollar in 16 months! Now that’s inflation!
