there is a link on the winni derby website about this very thing. It does state only Ethanol will be sold on the lake. it also gives you tips on how to deal with it.
I was told channel marine and west alton marinas fuel is allready treated with some type of product and you do not have to use starton or K-100. myself I would still treat the fuel with any product you decide to go with. Chack with the marinas.
