Is that fake news? I can't find Chris Fix and redline si-1 anywhere. Anyhow, my friend tested it only after seeing the results in the first two video's, and now there is a third and follow up video that showed the second bottle turned the piston tops to like new condition. And after he saw those video's, he went and bought a boroscope not even knowing what his pistons looked like. He was blown away at how caked they were, you see the pics because he posted them, and then you see the redline starting to work. The stuff works, and we did everything we could to either verify the results by duplicating them, or if it didn't work say so and in that case the results may be hit and miss. But as the picture shows, Redline sI-1 cleans better then any pour in out there. Before that pic he used Amsoil PI and twc3, and despite that his piston was caked, no metal showing. Used Redline sI and boom, night and day. Apparently the other news is it takes two bottles and two tanks to make the pistons like new, and I'm sure Corey will follow up in a month with more pics, to once again either verify the results by duplicating, or say it didnt work as good, whatever the results are when he finishes. The dude is just trying to help people and putting in a lot of effort to do so.
