Just this week I did some mileage runs with the internal computer on my Volvo and over a 24 mile measured course (all variables controlled as much as possible) I got 28.5 at 70 mph and 30.9 at 65 mph. Not 65 vs 55 like you asked, but useful info. I strongly suspect it would have been over 33 mpg at 55 but tht is a guess.

Some specs:
Speed controlled by cruise control
no traffic, no wind
windows closed, no AC
A-A-B-A

These numbers were just baseline numbers to allow me to evaluate a front air dam I was adding. Just FYI, mileage improved to 30.7 at 70 and 32.3 at 65 with the air dam, so I'm keeping it. Looks good, too.
