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?

odds are NOTHING Ina can is going to fix your issue, sounds to me like you got a lot of use out of this vehicle, maybe try funding a used catalytic converter in better condition than your's(*lower miles) at a salvage yard
