Several companies use deceptve marketing tactics, to convince customers that their "miracle" product will "prevent, fix repair and/or reverse" all ethanol-related fuel problems - No such miracle product exists!
These deceptive and misleading marketing strategies have been seen most often for products marketed and sold to marine and boat engine owners. Every fuel treatment product I have reviewed in recent years, that (deceptively) claims to remove water from ethanol phase-separated/water-contaminated fuel has contained ethanol or other alcohol!
Yes, alcohol does amazingly absorb water and have solvent and cleansing capabilities-
But, why would anyone want to add alcohol to fuel that has already become contaminated because of ethanol alcohol present in E10 ?
Additives that ncrease the alcohol content of gas over 10% will invalidate most engine warranties in engines designed for E10 (10 % ethanol max limit) and all warranties for engines that recommend non-alcohol gasolines. (Check your owners manual and warranty).
To add further insult to customers buying these risky products that already make matters worse, the same companies often falsely claim that their products will "FIX" or "REPAIR" phase-separated gas and return it to it's original composition...Impossible!
If there was a simple product or chemical that could prevent all the negative side-effects of ethanol in fuel, the major gas companies would already be adding it to the gas ingredients.
