As the title says what's the best fuel injector cleaner for the S?

I use 1/2 of a bottle of "Red Line Complete Fuel System Cleaner SI-1" in a full tank of gas about once a year.

BG44K / BG Fuel injector cleaner

Redline also makes great products

i swear that stuff fouled by plugs. Car had plugs about 1 year old and about 10k miles, ran a tank of that stuff and when i filled up again my check engine light came up, pulled the code and it was for engine misfire and random cylinder misfire,....changed the plugs and i was good to go.
i dont know why it did this but i am a believer that our gas we run has enough cleaners in it to begin with and we don't need additional treatments

I wouldn't dump a whole bottle of Redline in the tank. Our tank is small so the concentration will be slightly stronger. I usually put in maybe half a bottle for every full tank.

i used lucas because i used to get it for free from the lucas rep that used to come in to my old shop...it seemed to work well, but its hard to tell

The cleaning chemical that is strong enough to work in one dose/bottle is PEA, Redline's fuel system cleaner is reported to have the highest concentration of PEA, followed by Chevron Techron. Regane used to have a decent amount of PEA but I'm not so sure about the new formula. One bottle of Redline is enough to do two tanks on the S2K, I used one bottle a year for good measure. I was surprised how clean my valves and intake ports were after 60k miles, not too shabby.
