I just moved to Portland from CA and I need to register my car in OR. Also, I have to pass the emission test first. I believe my car gonna fail the test coz I dont have a catalytic converter. I was told that you can put something in your gas tank so that you can pass the test.

ANYBODY HERE KNOW WHAT TO PUT IN THE GAS TANK?

Thank you so much.

 

I'm pretty sure you're going to fail because you don't have a catalytic converter, there is no magical potion you can add to your gas tank.

You just need to go to an exhaust shop and have a new cat installed, simple as that.

 

Oh ok. Thanks man.
