Nice. What was the distance traveled to get that average? I get almost up to 25 if I like coast to a stop at the tolls about 12 miles from where I refuel... From there, it's just downhill, figuratively speaking. Usually I average around 20 but that includes some short trips, traffic congestion, and occasional pedal mashing. But I have the 3.42 gears which I don't think is as helpful with mileage.

The gearing is important, but my wife's car coasts more, too. The shifting program is very different, too.

I just drove round trip from Los Angeles to San Diego (288mi) total and averaged 24.9mpg. That was no AC and an average speed of 68.9mph. I have the N* and my tires were at the standard 32psi. I only drove less than 5mi off the freeway and never hit any traffic (if you can believe that!!!!). Around town though I usually get 16-17mpg.
