3 Pack Boost Up Catalytic Converter Cleaner, 120ml Fuel System Cleaner for Car Engine, Exhaust Carbon Deposit Remover, Reduce Emissions

From all the reviews and consumer reports I could find on this product, it is very effective. I'm not sure how I will be able to tell if it actually works. But lab tests are positive. The last thing I want to do is replace a cat converter and any emission part affected by it. I hope this 6 ounces of prevention pays off.

We did. My husband has been complaining that his car is having issues with the catalytic converter. So I decided to order this product and give it a try. He just has a little get around car that we paid under $1000 for and it's not worth really fixing up so we decided why not give this a try. It seems to be running better since he put this in and he drove it around for a while. It is really easy to put in and follow the directions. I think it's a good value for the money and it would be worth it to give it a try if your car is giving you issues as well.

Will try tomorrow. I have a 40 Gallon Tank so I will put all 3 in my tank. My Converter only gives me a light once a month but its not gone completly. Just has small amount in code. Hope it helps.

Came individually wrapped in a box the only thing i would change would be on the page where it says to dump in the oil instead of the gas tank. 2 different spots and if someone didn't know could cause problems.

This package came with 3 individually packed catalytic converter. I put it in on low fuel and drove for a while and my dashboard light went off. great buy!

been having problems with my sub shutting down. got O'Reilly's to put it on the machine and it says my catalytic converter needs replacing. hoping this will help clean it out until I am able to get another one. only time will tell....

I added it today to my fuel tank seems to be working okay I'll keep you posted it seems to be a nice stuff

RayHong I've used this product before. I thought it worked pretty good, I noticed the vibration came down to almost no vibration, so I didn't hesitate to repurchase another bottle… simply add it to the tank (a full tank/quarter tank) and go. I put this in my Honda , so it's recommended.

Small in size compared to a lot of the others , Added one so far %26 seems to have given the old engine a little more boost

Does not even begin to work for intended purposes. Zero total effect. Prefect scam. Wast of time and money.
