Many people here on the board and some others I know swear by this stuff. I used Seafoam one time and swore I would never do that again. Ole Blue ran like AppleSauce and when I finally got it all completely run out from my tank, I had to change plugs. They were fouled out and looked like they were run in something that had a lot of carbon build up in the heads. The plugs I changed out only had about 500 miles on'um. Hope everybody looks at the chart. Quote from chart:Avoid additives that contain strong solvents, alcohols and water-absorbing ingredients when gas contains ethanol (e10). Improper use of gas additives will increase risks, cause damage and invalidate engine warranty.Beware of misleading product claims, it is scientifically impossible to "remove all water from fuel" with just a liquid additive.
