Happy owner of twin 4 stroke 150's. Will ring free benefit these engines or waste my $$? Kyle

Sorry for the ignorance, but what is Ring Free?

[<boats.net>]

It is a fuel additive that will clean carbon deposits from rings and combustion chamber and O2 Sensor. It also will help Injectors and carbs

if not near a yamaha dealer, is there any aftermarket additives that will do the same thing?
