Most cars will in fact burn less fuel at 55 mph than at 65 or 75. In F-bodies we're lucky enough to have 6th gear, but I learned that my cherokee would get 23 mpg or more going 55 mph coming back from vermont than the 18 mpg it would get at 75. The new HHR is also geared so that 60mph is the magic number, going up to 65 mpg "drops" to around 31 or so, where as at 60 mph, its around 33-34. At 55 on some of the state roads around here, I got up to 37. So, no, it wouldn't be a terrible thing.
