Best 02 Sensors for Race Gas - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

OK. I've done tons of searching on this topic, but I'm still gonna ask my family too. "That's you all" fellow Supercharged Camaro owners. Mine is a 2010 ss full SLP exhaust, CAI, Edelbrock supercharger with 3.2 pulley making 10 psi, etc.

I just got it Tuned for the smaller pulley and 102 octane gas which I'm going to run in it all the time. 3rd car sits a lot. As we all know the lead gas eventually kills the o2 sensors. I'm ok with that. YES the tuner shut off the bottom two, but not the top two before the cats because you do get a better tune or better running car with them working. They do help. Yes I could delete those as well but trying to avoid it.

So... the questions: Which sensor should I go with?
Who has had good luck with what sensors? How many miles before they go out?
I've read FJO or Bosch? Wide band?
ALSO... should not need to re-tune because I changed out the top oxygen sensors to a new brand right? Should not change anything?

Some countries still use leaded gas. You would think you could get some of those

You still have unleaded fuel options up to 110. I run C16 in mine and im still on the stock front 02's.

Running leaded race gas full time in any car that sees the streets is silly.

No o2 sensor likes leaded gas, and you can't just replace the fronts with other brands.

Go with stock replacements. They are Denso I believe. You'll be fine with them.

Unleaded fuel is now available up to 125 octane now. Here at the shop we have anything from 110 to 120 here.
The 02's and the wideband won't like the leaded fuel for sure.

I have read other places on line forums as well that Denso lasts the longest. Even if they aren't the stock ones guys are switching them out to the Densos.
I only put around 3k miles per year on the car so we will see how long I get out of them. Should last a while.
It would be nice to use lead free race fuel, but it's twice the price here in MO, or to get it shipped to you, the shipping fee is crazy.
I get pull right up to the pump here in town and put in 7.90 per gal 110 octane. Cheap and convenient.
Thanks

At only 10psi on a pretty mild build...why are you even bothering with the hassle of race fuel...nevermind leaded race fuel ?

It'd be cheaper and easier just to dump some methanol in the tank instead.

X2 on the "don't use race fuel" vote. Not for 10psi. You're not going to make any more power with race fuel on a mild build with 10psi, and you'll have more headaches to deal with.
Tune for e85 and you'll make more power without the headaches.
