Cataclean?

Recommended Posts

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?

When I worked at AutoZone, we had it on the shelf and almost never sold any...for what that's worth...

Thanks for the info and sorry it took so long to get back. 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?

If you want to make it to half a million miles just buy an aftermarket cat convertor and put it on.

 

 

 

those chemicals you wanna dump in the fuel tank for a Lean condition to get that cat glowing trying to burn it clean...ain’t exactly good for alot of seals, orings, and gaskets.

 

But you can try running it on laquer thinner....let us know how it goes.
