What advantage do you think you get by filling your fuel tank with premium fuel? It does nothing for you except cost you about $0.60 extra per gallon. The only thing premium fuel does is raise the antiknock margin needed for higher compression engines something you really don’t need in a non-running engine while your rig is in winter storage.
