Re: "the ethanol conspiracy"
I'm probably feeling contrarian, but I disagree. Even out here in God's own garden, all the good gear-head boys were pumped up to hate E1X gas. But it's a red herring. Do you prefer we coat the world with lead again?
It's an oxygenator, and it's renewable. Really smart gear-head guys are building for E85 (if they can get it), because they can run sky-high compression and not really need to worry about cooling. I'd run E15 93 octane if I could find it. You can run higher compression with it than without. Yes it's hygroscopic, and old (REALLY OLD) carb gaskets don't like it, but I've never had an issue with a set of rebuilt Dellortos running E10, and dealing with the moisture means topping off the tank at the end of the season, and dumping a can of Sta-Bil in the tank. I might run it through the carbs, or I might just turn the fuel off. Either way, I fail to see how it makes my life worse in any substantive way.
I'm not a huge Jamie Kitman fan, but he's doing a 2-part series in Automobile Magazine that says it better (or at least differently) than I can. Here's part one.
Tune for it and be happy.
