Unfortunetly all of the fuel stabalizing products are designed to do the same thing - absorb water - that is why ethanol was put into fuel to begin with - that being the case, all of the fuel stabilizers have some form of alcohol in them - Sea Foam has rubbing alcohol and Sta-Bil has propanol - so in effect you are compounding the problem - however, I do believe propanol does not evaporate as quickly as alcohol - but I have seen Sta-Bil coagulate from too much water content - I just store my stuff with race fuel!!
P.S. - did not mean to steal the thread!!
