Andrew's spot on with the advice for hills (also known as Driving With Load): the idea should be - where traffic permits - to monitor your instant mpg at that time, and modulate the throttle to keep it above some arbitrary MPG that you want to maintain. Depending on how aggressive you are with your target will determine how much you play (lift) the throttle and lose speed on the incline.

Now this was exactly my thinking, but over on gassavers, I was chided for not looking at things correctly. I'd pointed out that by slowing down on the upslope, I was able to maintain at least 22 mpg verses around 9 mpg with cruise which was taking the engine right to the borderline between boost and vac in my saab. But I was told to not put so much stock in instant mpg which left me wondering why I bought a scangauge???
