Omaky 2 Pcs Catalytic Converter Cleaner, Auto Parts Engine, Exhaust System Pipe Carbon Removal Cleaners, Catalytic Convertor Cleaner, Fuel System Treatment Oil for Gas and Diesel Car

It does work I bought 2 of them first one did nothing but as soon as used the second one the light when off it’s been 250 miles and still off I think it works just follow instructions in my case used 2 bottles I’ll get 2 more just in case so far it’s working as it should hopefully that will save me lots of $$$$ by not buying expensive cat since I live in California they can be pricey I would definitely recommend it try it.

Effective only for one month, then the engine warning code P0430 returns to your dashboard. In my opinion as a mechanic, don't poison your engine and repair it. I ALREADY USED IT ON MY TRUCK AND IT DIDN'T SOLVE ANYTHING.Efectivo solo por un mes , luego el engine warning por codigo del catalitico P0430 regresa a tu dashboard, mi opinion como mecanico no envenenes tu motor reparalo YA LO USE EN MI CAMIONETA Y NO RESOLVIO NADA

I received what I ordered thought the bottles were a little small not a big deal I guess I have used it but I haven't really noticed any change of anything any improvements can't really say that it worked or it didn't

BUY IT

Yeah, I made it run while the gas was full. Didn’t really drop the O2 sensor lights.

wow, I spend money on spences catalytic converter cleaners and nothing work. I try this product, 1 bottle with 1/2 tank of gas (nothing happen), after 2 days I used the second bottle and on the second day wow my service light go off and my car is running really good. I recommend this product 100%.
