What kind of breakfast cereal were you eating during the period you correlated these results?
Because you probably have as much reason to blame that as the gas station.
How's this: I have 10 year old and 15 year old GM vehicles and have run only the cheapest gas in them for over a 1/4 million miles total, and have had no O2 sensor problems.
So I'm going to make the better correlation that it is 100% your particular 2005 Honda model that has a problem performing the simple function of turning cheap gas into reliable miles.
Go look up wideband (some, I think I said) O2 sensor and getback to
me Mr GM. Also cheap has nothing to do whether it has ethanol or not. Your the one that’s pissed because you have GM cars that are now Goverment, not me. Mine quit tripping the sensor after a few tanks.
