W00t! With the input from this forum, we've bumped the last two tanks on the Subaru up to 26 mpg! EPA estimates for the 3.6R are 18/25 with an average of 20.

Those tanks are also mixed between my driving and my wife's driving, and I don't have her on the hypermiling kick yet. I also haven't aired the tires up yet. And there is still a bunch of experimenting to do to find peak FE on certain stretches of my commute. Basically, we're already ahead of EPA, and there is a lot of headroom for further improvement. This is kinda fun. Of course, this is coming from an aero engineer with a love of physics, so my idea of "fun" may be a little warped... ;-)
