Amsoil Gasoline Stabilizer provides superior corrosion protection compared to Sea foam. 

Along with corrosion protection Amsoil Gasoline Stabilizer provdes longer stabilization than the competion. Using ASTM test D525 which uses an accelerated method of attacking the fuel Amsoil Gasoline Stabilizer exceeded 1440 minutes with Sea Foam lasting 690 minutes.  Raw Gasoline lasted 740 minutes.  Sea Foam actually reduced the performance of the untreated gasoiline from the pump.  Gasoline will react with oxygen over time producing Varnish and Gum.
