I've recently done a little more reading on E85, and I'm contemplating an experiment. I only have a few stations in my (greater) area, but it happens that one is near my regular route (it adds about 4 miles to the total trip).

Anyway, my car (even tuned) runs on the rich side (~11-12:1 AFR), but I was reading that stoich for E85 is actually 9:1. Now I know that I might be seeing a decrease in power, but would this essentially be forcing my car to run in a lean-burn mode?

I'm also thinking that, given the bad gas we have in CA, I would only see benefits from the higher octane rating. The idea that E85 is ~ $0.50/gallon cheaper and I only have to fill up once a week (i.e., I'm only going 4 extra miles out of my way every ~ 350 miles) is also appealing.

Regardless, I'm thinking that I might want to test this out... if nothing else, just to see the results. I've fallen into a pretty good routine, and though I wouldn't be able to give an accurate A-B-A testing, I could probably come up with a good estimate of how e85 affects my FE.

I'm due for a fill up tomorrow night, so unless I hear "Danger Will Robinson," I think I'll give it a try.
