I do hand calculate every tank of gas. My numbers since new are on Fuelly if anyone's interested.

I understand the function of Tow/Haul. In addition to using it, I locked out sixth gear since even on flat ground, the engine could not maintain 55mph in sixth. It would shift up and then immediately shift back down. In the interest of saving my transmission, I used fifth as my top gear.

Thanks for the info on my "Snapshot" question. Your answer makes sense.

The referenced PDF is mostly beyond me, I'm afraid, but I do understand the gist of it. It definitely backs up your statement.
