Gas Mileage?

Funny...., I don't do much interstate on a normal day to day basis. On one of my loops in Kentucky back roads 45-50 mph, not many stops I averaged 58 mpg. Coming home yesterday on I-75, running 70-75 mph I reached down and checked the fuel computer and I was getting 46 mpg. I was shocked! That is a huge difference.

I did a little experiment today. I rode 105 miles out, all interstate and state highways, averaging 70-75 mph, filled up when I got there - 46 mpg. Same route back, averaging 60-65 mph, filled up near home - 53 mpg. No appreciable difference in headwinds or elevation at the end points. No doubt, that extra 10 mph sure ratchets down the mileage!

Seems to meet the engineers claim that it was designed to run most efficient around 63mph
