i wasn't patronizing, i was pointing out an obvious fact. assuming you're driving consistently with the same start and end speeds, accelerating downhill and shedding speed going uphill (with the gas down the whole time) vs. coasting downhill (with no gas) and maintaining speed uphill (using more gas) would net an equal amount of gas consumption. this is basic physics.
Perhaps I'll refine my wording, slightly. Mild acceleration downhill and minimal throttle uphill.
If you close the throttle down-hill, then the dynamic braking of the engine is counter-productive. So you are not using the downhill to your advantage, and then fighting your way uphill.

I have interest in E85 as well, although as of now it is unavailable in my area.
Rogue, is higher boost the key to your MPG, as most flex fuel vehicles have less MPG on E85.

Using E85 will always return a lower MPG then Gasoline. My MPG numbers was on premium Gas. I really haven't tried for the best mileage possible on E85, simply because I can't keep my foot out of it.
To return the best MPG, you want to stay out of boost as much as possible.
The reason I run E85 is that it allows for very high boost levels without knock, and can be bought at the pump for significantly less then premium gas.

Yes, you will not get better MPG on E85. Im running E85 to try to come out cheaper per tank. Run a little more advanced. Support an alternative source of fuel. Id like to see more stations get it and more solutions funded.
I take 700 mile round trip runs 3 times a month. I try to stay off as much boost as possible on the drives. E85 can run pretty lean cruising. I am going to get an average of what kind of MPG I can get out of this stuff. Some others have proven the power levels E85 produces. Im gonna see what kind of economy it can render when needed.

as much as I love E85 I would never suggest it for best mileage over gas.
However after running it so long I just took a road trip in my little mini van and I can say that I truly hate the smell of regular gas (had to use it on the way out). Fortunately for me I found 2 stations along I 70 in KAnsas that had E85 so all is good
