Actually my friend use, say in his car okay, so ask me to try. So went and pump one full tank of the FS Ron 97, then my car like got no power already. Next day siphon out and put into wife's car that can run on Ron 95 one, then pump back my usual Esso Ron 97Wah.. Now spread to city already... They really thirsty for $$, they will kick all their customer away like this...
