Official Redline SI-1 thread.

Do you get any smoke on startup when you do this? I get a little smoke at cold start when I do. Clears itself up when I refill the tank though. And I too notice idle and driving improvement.

Zero cold start smoke whatsoever.
Just a happy HEMI.

Freaked me out the first time I saw it. Checked everything to make sure I wasn't burning oil. 100% positive it was SI1 mixed in high concentration. My truck is straight piped though, wonder if thats why I see it.

Interesting, you know sea foam does this because it is super concentrated 100% solvent right on piston tops. Burns that carbon off real good, never heard of this with si-1. It really brings up a great question, because if anything else all of the info in this thread proves concentration level does matter. If I have an opinion on this, I would want to do a long trip after or during this strategy, get that catalytic converter real hot and get all that ash off that. I would get a boroscope and put it down a plug hole, see what's up.

It's hard to know what the sweet spot is, but I would say at a minimum I would want a full bottle of si-1 per full tank, and then possibly using that bottle in a half tank do present great possibilities. Or even in a quarter tank. Thank for all the guys bring this up, worth considering. IMO this white smoke is a good sign, maybe not for catalytic converter but Good for cleaning carbon.
