The biggest factor is always speed, so giving mpg value without speed is garbage IMHO.
On several big vehicles I noticed higher mpg in the mountains, than on flat freeways. That made me scratching my head for a while, till I concluded that in the mountains I drop the speed by 20mph, what gives me ca 30% better mpg.
So even when grades will eat 15%, my fuel consumption is still lower.
