   Worked great! Engine light went off before the tank was empty. Light came back on about a week later, so I bought another bottle and the light has been off for about 2 weeks now.

   Had the check engine light in my 2008 Chrysler Sebring for the catalytic converter come on. Used the Dura Lube as recommended and the light went out after about 50 miles. So far it’s stayed off, so I’m very pleased.

   I had a mechanic tell me I needed an expensive service to clean my catalytic converter. I used this twice (two months apart), my mechanic thought I had put in a new catalytic converter when I took it to the shop yesterday!

   Delivery was slow (5-wks) But it worked as described my 2011 Mazda was running rough and I didn’t have money to cover the repair cost. The product worked and hope the smooth drivei will last long enough until I save funds to fix the issue.

   This product was great! I noticed an immediate difference in the performance of my truck. I was getting a gassy exhaust fumes smell and it was idling rough. I added this product and I no longer have any issues. The best part was, being in AZ, I noticed that my AC started running a lot colder! Highly recommend.

   We have an older Highlander and when I brought her in to a shop for a check engine light, they said I would need a new Cat. And the quote was ridiculous. So I was later recommended to this product and it’s worked great so far. I will continue to use quarterly to improve and maintain my old girl.

   My 2010 Honda Accord failed the smog check test due to a dirty catalytic converter which caused the service engine light to go on. I bought two bottles of DURA LUBE Severe Catalytic and Exhaust Treatment. The first one with a full tank of gas did not cause the service engine light to go off but the second one did. Took the car to the testing center and passed the smog check test. Couldn't be happier. This stuff really works.

   After the engine light came on all three of my cars, due to the catalytic converter issues, I would add a bottle of the Dura Lube Severe catalytic converter treatment to the gas tank, and it worked every time. No check engine light and the vehicles passed the smog test.
