My initial MPG run, yesterday, came out to 30.5 mpg. That's with a lot of playing (for break-in purposes, of course). A couple of your stereotypical Civics came by, wanting some. They had to be put back in their place. And, whenever I had open road, every 20-30 miles. I'd wrap out 4th and/or 5th gear. So, I think 30.5 mpg wasn't bad, considering.
