Rule of 7's

Just got the burb back on the road and took her down to the lake over the hills and dales in SW KY. Ran better than it ever has, smooth as glass and plenty of power. It occurred to me that I can tow that trailer all day long at 70 mph, 7 days/week, and get 7mpg consistently. Hence the Rule of 7's. Actually 3 tanks computed at 6.92 with startling consistency....I need to consider if 65 produces any savings.

Fresh water was full, TT was about 8800 lbs FWIW.

    I know what I'll get at 70. Just a little better than what you get. I wonder what you would get if you ran 62 mph?...

    So happens the speed limit is 70 on this stretch of highway called the Western KY Parkway. Very smooth road surface, extremely light traffic to the point where passing or being passed is rare.

    If you like to drive at 70 I doubt a little fuel savings will slow you down.
    Have you checked the mileage at 40?

    Two honest people in the same thread about mpg. It's a first on this forum :).
