1 - Gas already contains xylene and toluene, they're considered aromatics.

2 - Ethanol addition is allowing them to blend cheaper fuels, both by the addition of esters, and because of the addition of esters. What this means is that they're getting Ethanol and blending it at a lower cost to themselves, as well as making fuel which compliments the higher octane rating of ethanol (by making a lower octane fuel), which is a cheaper formulation of ingredients, because the ethanol addition just raises the octane back up to a "normal" level.

3 - It's not an agenda, so much as disgust. How about you go buy some 60/40 hamburger meat, and pay $3.00 per pound for it? Nah, you wouldn't want to do that, because you can get 80/20, which has more substance, meat, nutrition, etc... for the same price, right? I bet you'd be kinda pissed if the FDA/USDA said there was too much fat leftovers from food processing, and mandated that all beef products must be produced with at least 40% fat by 2012... but you're still going to pay the same price for it, including upcoming inflation.
