I bet they're just putting in more Anhydrous Alcohol in the fuel, and calling it special additives, what a load!
Why not just go full Ethanol on all cars and stop yankin our chains with BS lingo. I posted in another thread about Ethanol and how it will clean your engine, the stuff is awesome, but it seems the gas companies are buying it all up from the corn mills, which is raising the price of alcohol. Another benefit from 90% ethanol is super high octane ratings. which is what I think they are spiking our gasoline with to bring up the numbers. Meanwhile they make insane profits from less gasoline and charge us more for the cheap alcohol! Sux to be the little guy.
The octane rating is higher but ethanol does not have as much BTUs as gasoline so it would take more ethanol to equal the performance of gasoline. Gasoline octane is obtained by blending in light ends like butane, butylene and sometimes toluene to raise it (used to be MTBE which was cheaper but EPA won't allow it anymore so there is some price increase there).
