I've forgotten the exact changes in specifications for summer vs winter fuel. In winter, oxygenate may be omitted as smog & depletion of ozone is less critical. Also, fuel vapor pressure is increased by adding increased proportion of butanes and similar - which helps volatalize the fuel (that was a problem with carburettors but less so with fuel injection). How did the loss of performance show - harder cold start, hesitant running, poorer acceleration? First two indicate gas is still at summer spec's or similar, the third might indicate poorer octane/energy content in fuel due change in components. And - though it should not be - it may be that you got the wrong (worse) octane grade at the pump. Try another brand or different station.
