Gas engines do not get great mpg when they have to run under load all the time. Diesels love wide open throttle, but if you look at mpg for 4 cylinder SUV's you will find their mpg is worse than most gas V8's - simply because those little engines are always working hard.
My 2 cents

?? My 25hp subaru 360 run to the floor gets 50mpg at roughly 70mph!
But then again it is designed to be run to the floor and is tuned for that, anything under 80% throttle and efficiency falls pretty quickly.
