Cataclean?

2011 Crown Vic here with 305k miles, and today my engine light comes on. Scan at the local Advanced comes up with 4 codes on the cat converter. Guy says I need to get something called Cataclean and run it through the gas tank to correct the problem.


Is it worth doing this...will it make the engine run better or get better gas mileage?


Should I use Cataclean or some other product to get this done?

Yeah I'm not opposed to taking the cat out altogether but I've read it'll make the exhaust louder and I rather not see that happen for now.

The check engine light went off but it came back on yesterday so I got the codes read again. Guy's machine read 4 codes but said they were all the same code...P0430.

I'm game for the lacquer thinner option I've been hearing about. I see low voc lacquer thinner for sale. Wonder if it matters which version you use?
