I’m rather fond of keeping meticulous data about various things and the list of such things certainly contains statistics about my car. Having finished the trip east, here are some numbers from the trip:
Odometer leaving San Francisco, CA: 1715
Odometer arriving Austin, TX: 3532
Odometer leaving Austin, TX: 3540
Odometer arriving Atlanta, GA: 4730
Odometer leaving Atlanta, GA: 4730
Odometer arriving Concord, MA: 5837
Odometer leaving Concord, MA: 5850
Odometer arriving Woods Hole, MA: 5947
The following numbers are a little off because I started and finished with partially full tanks of fuel:
Total diesel consumed: ~115 gallons
Total cost of fuel: ~$340
The astute reader will notice that I have been getting fuel economy in the upper thirties of miles per gallon. This is correct and, when observed on a more granular level it does seem to be showing a trend upwards, though that trend is likely not statistically significant. As I intend to continue measuring my fuel consumption for the life of my car, I will be able to give better data later, when I am more than 6000 miles and 15 tanks of fuel in.
