so-called "premium" has higher octane than the assortment of straight petroleum distillates which make up straight gasoline... as far as I can tell that's the primary distinguishing factor between the 3 typical grades of gasoline at a typical station.

Ethanol's octane rating is also higher than gasoline, and serves to increase the final octane rating of the blended product.

So what else, if not ethanol, are they using to raise the octane rating on "premium"? Xylene? Not like that stuff is good for your fuel pump or the environment...

Hey all you guys who have an anti-ethanol agenda, I have an idea! Give me all your ethanol. My cars run awesome on it!! No idea what everyone else's problem is?
