2007 Toyota Camry throwing oxygen sensor lean condition after filling up with Costco 87

Hi RFD,

I recently switched to filling up my 2007 Toyota Camry with 87 Costco gas after filling up with 89/91 for the the past 14 years at Shell/Esso. I know it's highly unlikely, but the first time the code turned on, I filled up the tank with 91 and the light didn't come back on after I reset. I tried my luck with 87 a second time and the code came back on immediately I made a stopped and turned the engine on.

Is this just a coincidence? Or am I actually onto something?

I should also add that I recently replaced the oxygen sensor that is throwing the code.

Thank you in advance.

Your Camry is 100% configured and tuned to run on 87 octane fuel. 89/91 is not required in the vast majority of cases.

I'll chalk it up to an (original) oxygen sensor getting lazy after 14 years.
Deal with it.

Oxygen sensor is one of those thing that break often in many vehicle. Really isn't unusual.

If you have the 2.4L engine, it's more likely that your car burning oil is causing the 02 sensor code.

Invest in a piece of black electrical tape. It’s a 14yr old beater.

There maybe a difference in Ethanol percentages between 87 and 91 depending on the supplier. Maybe your car doesn't like ethanol.

It is normal of O2 sensors to go after 10 years...give or take.

Costco 87 has 10% ethanol and 91 has 0%

Did you use OEM or quality after market part? If it's a cheap part it could give up any moment.

Is there any code? Or just the O2 sensor?

If the O2 sensor was changed a month ago, you have warranty.
