Default Re: 02 sensor/check engine light

I noticed if I disconnect my positive battery cable for a few minutes and reconnect I can reset my check engine light. Sometimes it takes weeks for the light to come back on.My code indicated a o2 sensor but wouldn't specify which one the three was causing the trouble code. Does anyone know if different gasoline like shell or chevron higher octane can make a difference My v-6 flex fuel has 203,000 miles on it and still runs great.
