Sounds like you got exactly the same gas mileage as Goo. He got 36 at 70 and 27 at 80. Therefore, if you took the middle of each you would have 31.5mpg at 75 mph. Prob doesn't work out exactly like that but it would stand to reason that you are right in line with him.

Remember, all the Scan Guagers say there's a sweet spot between 62-67mph. That speed with cruise control is how guys are pulling 40+
