Severe Catalytic and Exhaust Treatment | 16 oz., 2-Pack

Ran 1 bottle added to 1/2 tank gas in Subaru Outback with 214K miles, vastly improved performance followed by 2nd bottle added to 1/2 tank and it did not seem to improve past just 1 bottle. Did not make ODB2 lights go off. fast delivery, good value, and I will buy again.

when your ride be going boom bang pow and dieseling when you come to a stop give this a try before your next step,mechanic

Can’t say if it did or did not help clean my cat system. Turned out the real issue was a manufacturers emission system recall

I purchased the 2 pack of Dura Lube specifically to address a persistent check engine light caused by a catalytic converter error. I made sure to follow the application instructions exactly as directed, but the results have been inconclusive so far. The error light continues to come and go intermittently, making it difficult to determine if the product is actually providing a benefit or if the timing is just a coincidence. Because I haven't seen a definitive, lasting fix for the sensor issue, I’ve decided to give it three stars.
