I've heard that nitrous will ruin your O2's pretty quick. Is it true?

is it true? Is there any way around it?

First time I've ever heard that. I ran it for close to two years on the my first mustang and never replaced my O2s.

Never heard that one before - but that's not to say it doesn't happen to some.

Nitrous, properly installed and used, will not harm your O2 sensors. As far as your rings are concerned, it will accelerate wear and tear on the piston/cylinder/rings, but that's the price you pay for any power-adder.

Take care,

The only thing that i have seen that will ruin an O2 sensor is using race gas. Race gas will kill an O2 sensor because of the lead. My friend ran a mix of 93 pump gas and the 115 race gas and his O2 went out in about 2 months.

Good question, I had a buddy put (3) bottles of octane booster in and then his sensors went bad and his gas mileage went to crap too. He is currently trying to find the cheapest deeal for some new ones at this time.

I agree w/ Chris on the wear and tear on your rings, pistons, and cylinders. That's a price I'm willing to pay

I killed at least one of my O2 sensors within 2 years and I spray. Probably a coincidence though.

I assure you the nitrous had nothing to do with your O2 sensor failing. Nitrous is 2/3rds nitrogen and 1/3rd oxygen. At around 600 degrees (give or take 50 degrees), the nitrogen "breaks down" and releases the oxygen. The only thing your exhaust will see is more oxygen, which can't harm your O2 sensor and in fact can help your cats. The problem comes when the system is installed wrong, and you have too much fuel being added. This won't damage the O2 sensors, but can trick the ECM into going lean, and can and will clog up your cats.

Most fuel additives (ie: octane boosters) have lead in them, and aren't intended for an engine that is emissions compliant. 5ohCOUPE is right that lead will harm O2 sensors, but not all race gas is leaded. Lead will destroy the cats, too. O2 sensors are very sensitive. I have seen O2's that were damaged because too much RTV was used on an exhaust gasket. But Oxygen, the by-product of nitrous, is what they were designed to detect, and thus nitrous won't harm them. As far as fuel additives go, make sure it says it's O2 sensor safe before pouring it in your tank.

Take care,
-Chris
