I live in north nj and learned early on about fuel stabilizers for storage. I rarely use them now because I I don't have any real long term storage needs. unleaded gas in our region is a 10 or 15 % from nov to april. recently, ive heard from a couple of mechanic friends that Stabil and similar products are not comptatible with winter blends. apparently, and correct me if im wrong, the additive does not miix properly wiith ethanol blends, therefore, its sits on top in the tank and is useless. if thisn is correct, than using non blend gas for long term stg is better. like I said earlier, I am just curious and trying to clear my internal 'cache' of bad info. side note: the 110 octane Powermist used on my racebikes warns of fuel degradation if additives are used. Any thoughts?
