1st Quarter 2009. Cold weather, winter gas, and only a 7% improvement over the same period in 2008 adds up to somewhat disappointing results. Cold weather impacts short trips the most with the warmup hit although glides are shortened as well. |

4th Quarter 2007 data. New engine break in period with mixed highway and suburban driving. 5.5 mile daily commute each way; some extended highway trips. This was before I discovered hypermiling. Typically driving the speed limit, easy acceleration and braking. |
