Wouldn't that make the engine run lean since E85 has a different stoichiometric ratio than gasoline?

Yes. You obviously have to tune for e85. And update your fuel lines.

Yeah, he's better off running a little race fuel mixed with the bad gas to "clear it up" until he gets some fresh fuel. I'd never run e85 without a proper tune for it

I wouldnt run straight E85 for awhile, Id just mix it to get either 93 or 96 octane. Quite a few guys run 93 with no problems. I mixed it when I was in NE and I had around 96 octane and it ran great. I only have about a 1/4 tank right now, so it wont take me long to get rid of it. I dropped the inlaws off at LAX today and that knocked it down there pretty good.

Be careful with the purity of CA E85

Working on hooking up both of my gauges and my new amp and sub. Should be done tomorrow morning.

How does this work? Do you have an article which you could point me to?

So I put Lowest: 91 Highest:105 (that's what I found E85 octane to be, online) To achieve 93 octane. Does that sounds correct?

And put in how many gallons you tank holds.
