Hi Davy,
It looks like nobody knows – I had a quick google and couldn’t find any reviews on the stuff you are asking about.
I did find this though which is quite informative : – http://www.fuelsystemguide.com/what-is-the-best-ethanol-fuel-treatment/
The Lucas Oil product is available from Amazon and gets good reviews. Personally I have not suffered any problems from ethanol so far and not tried any of the fuel treatments.
