Higher Octane Fuel and O2's

Flex · 04-19-2003

Has any one ever heard that a 93 octane premium will damage O2's? Someone has just informed me that he was told running premium versus unleaded would cause premature wear on those sensors. This sounds like bull to me, but any info opinions would be good.

93 is the only octane that I have run in my stang and also in my 91 pontiac sunbird convert that had a 3.1 v6 and both the cars where fine with the exception of the pontiac which my brother totaled for me but that had nothing to due with the octane so I am going to say B.S. it is fine on the O2's

Thanks. Any more? I think this is as bs as it gets but what the hell

I've heard all kinds of crazy rumors about running premium.. Someone tried telling me that premium will void my warrantee!!!

I would say its definite BS

It's BS... The only thing that will harm your O2 sensors and your cats is putting LEADED GAS in your car.

Jason,
Did you get my post on your own O2 problem? Did you fix them?

go back to your friend and agree with him... then tell him to use heads off an 83 corvette to improve performance.

Well Adam, it wasn't a "friend" so to speak but I believe it was a forum member that threw that at me. I too laughed at the suggestion but what the hell, sometimes people want more than 1 opinion.
