Just had a tune up done on my 2006 Ranger Z20 Yamaha 225 hpdi. My service guy said there were alot of carbon on my plugs and suggested i do a shock treatment with the ring free plus and then run it in every tank of gas. The instructions on the bottle does not give directions for a shock treatment. Could anyone please tell me the process of the shock treatment. Thanks in advance for any help.
Pretty sure its 2oz per 1gal.
Also all my bottles have it listed, I'll check when I get home.

Hey man you only want to use half the treatment on your first full tank of gas, after that go to the normal dose, you will probably have to change your plugs once or twice in the process, my mechanic told me that if you havent been running ring free and you start at the normal dose then it will try to break everything free at once and could mess some stuff up.
You can and should also run an engine tuner through it once a season at least. It is sprayed in through the throttle body with the engine running. I always did this on my two strokes before I winterized them.
