Berryman 0212 Emissions Pass Protection, 12 Fl oz

Worked like a Charm, Passed Emission Test W/O a Problem. Was pretty sure I would even before buying this product. But with a 13 year old Truck. I figured it was worth the $'s, to Guarantee that I would. Just Follow the Instructions. Wholeheartedly Recommend this Product... Definitely "NO PROBLEM " !

So, I added an oxygen sensor spacer to 1/2 rear oxygen sensors along with a bottle of this Berryman's elixir.The guys from the Under the Hood Show, and the Car Doctor himself, Ron Ananian speak highly of this chemical in particular and Berryman's overall. I trust their word, so I gave it shot.I gave it a try and it got rid of my P0420 code, but now I have a emissions code for the long term fuel trim. However, I think this code is from all the idling I've done while working on the car.If after regular driving, and I pass my emissions test, the code clears permanently; I'll change my 4/5⭐ to 5/5.One more thing, you know Berryman's Carb Cleaner is the real deal, case if it gets on your school, it burns like hell.

This product works, I had to get my 2002 Honda Odyssey to pass inspection and it cleared everything from the check engine light to the Tcs light, etc. If you want to pass inspection get it really works.

I use this product often, Works well.

Ok product

2011 jeep grand Cherokee i have use all brands including cata clean for catalytic check engine light issues .This was the only product work for me can not believe

THE BOTTLE WAS FILTHY ON THE OUTSIDE AND THE CHEMICAL WAS POLLUTED FOR SUITABLE USE?

My converter was raising an 0420 error, performance below threshold. Adding half a bottle to 4 gallons of gas, driving 15 miles, then topping up the tank, got my car performing well enough to pass the emissions test.
