My Experience It worked great for me! I was having a catalytic converter issue while trying to pass my NY inspection. I tried an O2 adapter before, but it didn’t work. Then I ordered this 2-pack and used one, and so far the check-engine light hasn’t come back. If you’re having the same issue, this may be worth trying before spending $2,000+ on catalytic converters. Just keep in mind that results can vary depending on the vehicle and the actual problem.

I used ny first bottle last week. Filled up my car to just over 1/3 tank and drove around 50km. The P420 and P430 permanent codes are now gone. These were in the car for about 2 years. 2010 BMW 528i xdrive. Will monitor this but.hopefully a few more treatments and it.should be good. I would recommend this to anyone with these catalytic converter codes to try first before undertaking replacing the convertor.

As advertised...time will tell if it works

Check engine light came on. UGH Who doesn't feel their stomach drop when that happens. Add to that it came on about 3 weeks before we were due for inspection in order to renew our registration. Double UGH! So we have it coded at the local auto supply place and it comes back to Catalytic Convertor. I call around and the price to swap out the convertor is about $2000. A simple further diagnosis was going to be about $200 before anyone would work on it. Its an older car and it wasnt unexpected. We have the money to fix it and while no one really wants to spend $2000 on a car repair .. you drive an older car and things happen. Our problem was .. it was a really really inconvenient time. We would have to rush to get it done in time for the registration renewal which would mean getting a rental car and more in order to go to work and not take the time. it was just bad timing and not finances that made it awful. So .. I will admit .. I didnt give this liquid magic a snowballs chance in &*^% of working but the wife said .. for $40 for the 2 pack lets give it a try and we can replace what needs replacing later. Fine honey but I think its throwing $40 bucks away. I used it as directed on a Saturday and then used the second bottle on the following Saturday and reset the computer. Drove it for about 9 days and no check engine. WIFE BROUGHT IT TO DMV TODAY AND IT PASSED INSPECTION!! Probably would have worked fine with just the one bottle but I figured since I was throwing money away might as way throw away more. Trouble is .. it wasnt throwing money away .. it just saved us about $1950 plus rental car costs and lost time from work. Product is AMAZING! Now we can take a little vacation time and address the problem without feeling rushed. Awesome stuff. Buy it
