Yah, the link said guy was running with the tiniest of induction leaks, and the system couldn't compensate on e10 and the mixture was almost always too lean (and that his mpg sucked rocks before he fixed it).

Analyzing the exhaust gas would be best, but what do your spark plugs look like? What color?
