It works

AverageDad June 6, 2016

I've used this stuff in the past, and I just purchased it to use on my son's car and it worked again. Seems that it does clean out the Cat and it get's rid of that rotten egg smell. Hasn't let me down yet.

No improvement after 3/4 of a tank. I'm not blaming the product, perhaps my catalytic converter is too far gone.

I used this on my vehicle with 123000 miles because the engine light came on for a bank 2 CAT deficiency. Tried to clean it out, but the engine code came back on. Maybe my car is too old and the CAT is really clogged, idk. I'm going to try another bottle, probably a different brand just to see if I can get the CAT unclogged.
