Is it true that all blends have some kind of anti-foaming agent in them. If this is true, then why would you add armorall. Just for the air bubbles. I know that armorall is a polymer, and could that leave a residue on the motor. Will that that in the long run hurt the motor. I saw the video of olds97 demostrating the 1shot spritz of Armorall to a gallon of fuel. It made a beliver out of me, but I wounder about the latter. :OMG:
