My engine light came on in my 2014 VW Toaureg. I did some research and found this product. I purchased a bottle at Walmart and dumped it in my gas tank. Only had to drive a little bit and I noticed an immediate change in how smooth my VW was driving and not long after that my engine light went off. Highly recommended using this before.

It turned the warning light off almost immediately
I was having the engine light come on periodically on my 2009 Chrysler Town

I don’t normally write reviews, but this saved me a lot of money! My check engine light was on so I took it to Auto Zone and it came up Code PO420. I took it to my mechanic and he said I would probably need a new catalytic converter. But, he recommended I try DuraLube Catalytic and Exhaust Treatment first. I added the bottle to my gas tank (about 1/4 tank of gas) and drove about 20 mins and the code was gone!
