gas-shok vs ring free ?

[Capt.Guy]

Has anyone tried a fuel additive called gas-shok ? my yamaha dealer says its better than stabil or ring-free and i have been using both stabil and ring-free cocktail for 6 troublefree years. kind of hesitant to switch, but he swears this gas-shok is superior in every way :roll: any feedback from users of this product would be great. thanks

If you've had 6 trouble free years how could something else be superior in every way? I'd be more inclined to buy a lottery ticket than gamble on health of my expensive motor.
