Hi Neil, I printed this a few weeks ago thinking I would do the calculations. Studying it brought me eventually to the end of the pamphlet, where the author says there are more variables than he originally thought and so the formula might not work well. Do you have a way around that problem? It's also too late for me to calculate a baseline.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
