   This product really works. I was having an issue with my catalytic converters on my suv due to high mileage. I added a bottle to a full tank of gas. By the time my gas gauge hit the half tank mark, the check engine light was out and my car was running smoother.

   Giving a five star because this product works but not for all. Didn't work on my 2005 scion xb with code p420. I had to replace catalytic converter. That's the only way it passed smog here in California.

   Unbelievable! I had a P0430 and two shops said I needed a new catalytic converter. Upper on the driver side on my Ford Expedition with 166,000 miles on it. Very expensive. So i bought the DURA LUBE and mixed it with 16 gallons and revved the engine as many times as I could while driving off the gas on country roads. 100 miles later the check engine light went off and has never come back (it was on for close to 2 years)! Also my power has increased and so has my gas mileage!

   And I passed because of this stuff. Im in California and mechanic told me I needed a new catalytic converter. Decided to do some research and some ppl seemed to bypass it with this. I bought one bottle, followed directions, cleared codes myself (have a $30 reader) and after going through a full drive cycle where 7 monitors came up the check engine light came on. Bought another bottle, cleared codes myself, drove a couple weeks to make sure all monitors showed back up and once they showed back OK i took it right to the smog test and we passed. This stuff works and saves me a solid 1k - $1,500.

   Filled tank Chevron 91 out in half a bottle, drove long time freeway, light came off itself. Was able to clear code afterwards and has been cleared since. Good for clearing out carb build up in car and cat. I heard if cat. Is 5-10% contaminated then light will come on. So just needs a good cleaning and will be fine! Highly suggest trying this stuff first along with bf44 cleaner. Also good just to use on cars with 150-200K+ miles

   This did the trick I was looking for an alternative after an emergency arose causing me to use the majority of the money I had been putting aside for this repair (I wasn't close but now I was almost back to square one). First I did research on catalytic converters themselves, how they work and typically what creates the problem. Then I went to YouTube and searched for Videos showing me how to do the work myself and stumbled onto a video suggesting a similar product. Read review after review and decided to give it a shot and placed my order. So glad I did. I followed the directions and it worked like a charm Unlike some my engine light has yet to come back on but I decided not to push my luck and be more proactive so got myself set up for auto shipments of Seafoam High Mileage The next time my engine light comes on and I get the same error message I know right where to go. Thank You YouTube, Amazon Customers and Dura Lube for saving me $1500

   I write very few reviews, but this Dura Lube Catalytic Treatment shocked me. My 2011 Camaro LS with V6 has had Code P0430 for more than a year. It is for a catalytic converter or O2 sensors either bank left or right fault. This usually will means things are getting dirty leaving the exhaust manifold. If you're a 49-stater, lucky you, new cats are only about $300. But I'm in Leftifornia where new CARB cats are $1600 each, so $3200. The car is only worth $7000 at age 10, thanks Chevy. I tried Chevron Techron gas, and many different fuel cleaners. No success. I bought this Dura Lube one week ago, added it to a fresh full tank of gas, and at 120 miles the Check Engine Light TURNED OFF for the first time in over 15,000 miles. My ODBII reader has a green light now and I'm racing to the Smog place to for an emissions test. Update, it PASSED.

   I was thinking it will not work but then I don't want to spend $1500 to fix my Catalytic 2011 Honda pilot. So I followed the simple instructions. I decided to filled my tank up with Super instead of regular and topped it of with this Catalytic cleaner. I drove almost 250 miles and the engine light turned off. So I think it really work. It is been about 10 days since I used it. I am hopeing my light stay off. Some people said it is snake oil..but give it a try maybe your catalytic is not broken.

   The product arrived quickly and it good condition. Dura Lube is easy to use. I am not very “car savvy” so I love when products are simple and do what they say. My car was hesitating when I started it. After taking it to the dealership, no one could find why it was doing that and recommended that I start using better quality fuel. It helped a little bit after using Dura Lube, it hasn’t happened once!

   I ran this treatment in my Silverado after having an engine light cycle on. After running this through my fuel system as the instructions the truck felt like it was running smoother and the engine light went off (you may need to give it a day as I did). I'm happy I give it a try and will use this in a couple company vehicles when it needs a good clean.
