last summer, I brought back 94 octane 'real gas' from mid ohio. Put it in the 750k1... the difference was instantly noticeable.
Ethanol benefits farmers, but I'm dubious about what it does for the environment. Even if there is a slight reduction in emissions, each charge has fewer btus, and therefore less power, so you're going to use more of it to go the same distance, and thus, be belching the more crap into the air.
Not all conspiracies are theories.
