update
 

since my last update I have achieved a best of 47.6 mpg for one tank of fuel. I have been averaging about 47 mpg for the past month.

65 mph max, I wonder what 60 mph would net me?

Very nice! There is only one way to find out. I'd guess 60 mph would net you 2-3 mpg though. You might be able to break 50. :)

You can check out the speed vs mpg charts to get an idea of what you might get:
