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!

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

I felt some better performance in engine

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.
