No disrespect to you guys intended but I often here rave reviews on products. I always wait to see scientific. Any of you run it with a scan gauge, or do some math, or put it on a meter to find out if you saw any improvement. Afterall my VX seems to have good days and bad days when it rubs better or worse. In addition you can run straight starter fluid and have a good burn but once you burn through it your back where you started so it may only be covering up the issue not solving it. I have never used it so I do not mean to disparage the product just want more detail.
