Thanks a million, guys. I'll go out & see if I can apply that and get positive results. This may help my averages a lot, because there are a LOT of hills/grades around here & I never really knew how to tackle them before.

But what about a gradual enough grade to keep it at best mileage speed with cruise control? I guess as long as I don't go above about 80% throttle and/or lose too much vacuum, eh? And if it's "too low" for maximum efficiency vacuum/throttle, it just means it's gradual enough to just treat it as "level" and continue at max mpg speed?

(just a bit confused by PaleMelanesian's report of getting better mpg by slowing at the bottom of the hill & actually acceleration up it. ???? All I can think is that's getting into the P&G techniques - keep throttle/engine at max efficiency even if it means accelerate, then when speed gets too high, due to aero, coast back down & start all over??)
