Citric Acid? To clean Catalytic Converters? For real?

[ravenmaster]

Wait, I am confused. How could it ONLY clean Cats from diesal engines. The deposits are about the same between Diesal and Gasoline engines (HC's, N0X, CO) so this trick would not work on normal CATS? If not...y?

From diesel motors, sulphur in the fuel and phosphorus from anti-wear oil additives can gum up a converter and prevent it from working.

A gas engine cat will self-clean if the engine is kept in good running condition. What really kills a cat is too much blow-by, so oil coats up the inside; an overly rich condition for long periods, and mis-fires, which send raw gas into it and over heats it to the point of burning it up.

So citric acid wouldn't do anything at all?

It might work, But it might be like being the guinne pig in a new drug experiment.

I'd only try it if I had failed the smog test, and needed a new cat to pass.

Also....
It seems to me that a lot of folks on this forum tend to say "ouch" if they have to spend the $60-$150 for a new cat.

That tells me they don't have (or don't desire) to spend any more than they have too on repairs.

I've learned that to support a car, you must plan on spending at least $100 month. This should be placed in a savings account to build up a reserve for the larger ticket items, like tires, and repairs you can't do yourself.

Agreed, However y ass makes 8.50 an hour so i am saving up for a new CAT but until then my car is out of reg by over a year. And I kinda need a "quick fix" to pass California Smog Standards. Thanks for your help. ill let you know how it goes :-)
