When to replace catalytic converter

[naeemdotcom]

Could you advise when to replace the catalytic converter in a 2022 Alto 660 manual?
How does cleaning compare to replacing it? The car has 35,000 km on the odometer, and there's no engine check light at present.
Also how about if use Cleaner in the fuel tank?

Why do you want to even touch it at such low mileage?
Just give the car a few hard runs once in a while and you most probably won't have any problems with it. (Unless some other problem causes it to deteriorate)

Thanks for your reply.
During my last visit to Suzuki Central Motors for a routine oil change and tuning, they recommended catalytic converter servicing. Instead, I chose to replace the spark plugs, which significantly improved the car’s ignition and reduced engine noise. I expect they’ll suggest the same service during my next visit, so I’m gathering some general information about it in advance.

That cat converter service is a money grab. Don't fall for it. Actual clogging of cat con will result in bad performance and fuel economy.
If it deteriorates, no amount of "sarvis" helps. Only replacement. Follow the Italian tune up method once in a while and your cat con will be A-OK (unless some other problem messes it up).

Thanks again for your reply..

Here is a quick gpt resonse:
The term "Italian tune-up" is aimed at improving engine performance, particularly in high-performance cars that spend too much time at low speeds, short trips, or idling conditions. The idea is that by driving the car hard for a period (often at high engine speeds and under heavy load), you can help burn off carbon deposits, clear out partially clogged fuel injectors or intake passages, and generally "exercise" the engine’s full range.

So, if I drive at around 110 km/h on the motorway for about an hour and occasionally rev the engine harder than usual, will it achieve the effect of an 'Italian tune-up'? Also, should I even bother doing this before I notice any performance issues with my car, or is it something best reserved for when I actually encounter engine problems?"

If you accelerate a little harder than usual when entering the motorway then that is more than enough. I'd recommend to give the car a nice pull, when safe, every fuel tank or so. Given the small fuel tank on altos maybe once ever two or three full tanks. Make sure to only do this when the engine is warmed up. Driving a car at turtle speeds all the time tends to hurt some cars, I've seen it with older Mercedes'. However, your CAT is probably fine and it really is just a money grabbing tactic.

I don't really know how I feel about cleaners that you put in fuel tanks. I always feel that the chemicals in that stuff would have to be too aggressive. You may want to put in a little bit of high octane instead as those are supposed to have some cleaners mixed in here, but that may be just marketing too.
