More than likely the station that sold the premium fuel wasn't selling much
of it and the fuel could have been stale (several weeks old) or contained
higher levels of moisture than fresh fuel.
Fuel injection cleaner or Berryman's B12 additive will normally displace the
water and get the fuel to burn on through without damage to your engine.
