I've been monitoring the onboard computer vs actual MPG at fill ups, and they are pretty darn close. I do a lot of Interstate driving, from Florida to South Carolina and back, and @ 80-85mph w/cruise, it usually gets ~16.3mpg. But after exiting the interstate to a 2 lane State Rd, and if speed is held to >62mph w/cruise, the onboard computer shows a fuel mileage of 21.4mpg
