Good information, very clearly presented, and far more valuable than the oft-quoted "my OBC shows XX mpg. An additional data point that would be valuable (over time) is to note the relative mileage during summer and winter, to see if winter fuel has any appreciable effect. You may not be a climatic zone cold enough for it to matter, but it would be interesting to see. You could also note that this is US mpg, for our non-US members.

Thanks for posting this.
