2X Cans Catalytic Converter Cleaner, Oxygen sensor cleaner, pass emissions, SMOG, fuel additive, combustion chamber cleaner

i love the fact that the product did what it said it would do at really good price. I'm going to buy it again and tell My friends about it too.

I got my check engine light to go off, so I am very happy with it. I like the little funnels that came with it made it much easier to put it in my gas tank.

exactly what I was looking for at a great pruce

I’ve used several different brands to try and get my check engine light to go off this brand works the best by far!

Made my engine light go off the same day. You get 2 cans so you can use one later if you need to.

I like that it the instructions were very easy to read and follow. would definitely purchase again.

I don't know how it will work but I know that the competitor cataclean seems to work. I bought this because it is 2 metal cans for the same price as one of the competitor. However, I searched and searched before I purchased it and there was no size or fluid oz information. Now that I have received the product, I see that the 2 cans equal one can in fluid ounces of the competitor. It's a little bit of a deception. That's why it receives 3 stars.

Car has engine light on for years now. Thought I would try this out if it helps or not. I just didn't see any noticeable changes from using this

I think it cleaned the exhaust system but it didn't solve my calculated converter check engine. but luckily I only had to replace one of them.

1 can down. hasn't worked. waiting to see if 2nd can makes a difference.
