Interesting, one would think that E85 has a cleaner, more efficient burn in the combustion chamber than premium fuel.
E85 has a stochiometric ratio of 9.8:1 compared to gasoline of ~14.7:1 (Depending on ethanol content in the fuel, true gasoline with 0 ethanol content is 14.7:1 and the typical "up to 10% ethanol added" pump fuel is 14:1-14.4:1 depending on the actual content). It takes more fuel volume for similar combustion event to occur, in the case of e85 by about 33% more fuel volume per combustion event which will lower the mileage.
Race gasolines can have different stochiometric ratios than pump gas too, it is really interesting (to me at least ) to learn about all the chemistry and "magic" behind what makes different fuels so potent.

Haven't seen stoichiometry mentioned in some time outside of Organic Chem class many moons ago...those were the days...

.... after 66.800mls I replaced the front droplinks on the Boxster this weekend. What a difference! Finally there's peace and silence from the front when driving bumpy roads.
What an increase in convenience for 50 Bucks and 3/4 of a hour of really easy work.
Still playing with the rear suspension. I turned the adjustment all the way to soft and yes the car feels like it's floating over rough roads. When I raised the ride height the rear tires began to howl like wheel bearings. So I lowered it back down and carefully measured bother shock and drop link lengths. More later.

Sorry I missed this earlier, we are the same in Canada, in that every process once has a different fuel blend, with Alberta being the worst, which has a certain sense of irony to it.
I do not recall seeing e85 at any Chevron at all here.
