Just got a 1995 Civic VX

For my older Honda's the two best MPG feedback tools I've found are an SAFC or VAFC, that way you can watch your TPS and vacuum. Plus, if you have access to a local tuner/dyno you can wring a little power and even lean out the top end a bunch. Even simpler is just a cheap vacuum gauge. The closer you get to 0 the more fuel you're using.

Oh, and find yourself some rear drums from a 1G Insight or 1984 CRX HF, they're finned aluminum with steel inserts, good for a few lbs of rolling resistance.

This was with minimal hypermiling techniques. Tires were at 35f/32r. Speeds were right at 60mph. I coasted with DFCO most of the time (in gear). The route I drove was not that flat (Seattle to Port Angeles). I am really excited to test on a completely flat section of interstate. I think 60mpg is not too far out of reach.
