Re: Interesting trip
I gotta agree, I think there's some variables there that are making the bigger difference.
Subtle driving differences, traffic differences, and the big thing, road differences would probably account for 90+% of the difference in the MPG. Even just having more cars on the road around you can make a slight difference.
During my commute, I use the Southfield Freeway (Over 15 mile stretch); the road itself seems to be more fuel efficient going South than North; a slight lean coupled with just the way the road is.
I've made the same trip to my grandparents, once with just myself, and once with my parents, a grill, and a box full of stuff. Both had the Cruise Control set at the same speed, and were done on pretty much the same route. (I got off an exit earlier the second time because of construction.) There wasn't a difference in MPG going. Coming back was a different story, because I managed to draft for most of it the second time. (Averaging 40 mpg on the return trip!)
