With my trailer and truck I get better mileage at 75 than I do at 67. the reason is because the rpms are bit higher which puts the engine into a better spot in its power band.
Since more speed requires more horsepower, and more horsepower requires more fuel, I don't think that it is possible to improve fuel mileage by increasing speed.
