41mpg at 75mph cruise in the rain in a non vtec-e Civic seems pretty good really. If you were actually pulling 41 at 75mph then you can bet you'd be up near 60mpg at 55 mph. Seriously, play around with the "Aerodynamic & rolling resistance, power & MPG calculator" on this site and you'll see.

Congrats! Car look cool too.

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.
