I've noticed that my average MPG is better in town than at any highway speed, unless there is a tail wind. Even though that means not being in high gear. Otherwise, on the highway, the slower the better. Just my observations.

That is hard to understand unless your average highway speed is 65 mph or higher. My experience is the opposite. When I went to Alaska I averaged 8.5 mpg on the highway driving at 55-62 mph. In Alaska I averaged 8.3 mpg because the roads were dirt could only travel at 40-45 mph which means I was in 3 rd gear most of the time. Weight plays a role also. I was heavily loaded on that trip always traveled with full tank of water and a lot of stuff. Ave for most trips was 8.7 mpg.
