ill also add this disclaimer...at least for my vehicle...
the mpg loss that occurs when i go above 57 to get to 70 is far exceeded by the gains on the coast back to 50. ive tried both ways on the same stretch of unobstructed highway and over a 2 mile stretch i saw more than 1 mpg gain by going to 70 instead of 65.
my rpms are only gradually affected to get to the extra 5 mph but i can coast nearly 1 mile on the flat stretch by getting up to 70
