I'm pretty sure that any "octane booster", available at any auto parts store, will do the same thing. My friend works for the A.Q.M.D. and he told me this. I have a VW shop and I see carb floats, needle and seats, fuel pumps, and of course fuel hoses being affected in a big way. The new gas doesn't burn as hot as the real gas resulting in worse milage. So in reality you're using more gas to go the same distance. The only benefit? To who? They sell more gas, more taxes are generated. It's more BS from your Government.
