Same for any other flush.
To maintain the system correctly, you clean it BEFORE it NEEDS to be cleaned.
Same thing with oil. You change it before it NEEDS it.

......
comparing an oilchange to using an injector cleaner to get a better spray.... or a chemical cleaner in the radiator to remove rust..... or an engine flush..... isn't exactly the best comparison
oil degrades... but almost never would I reccommend using an engine flush (at the most maybe a quart of dex 3 to help a sticky ring... but that's generally after the fact that something bad has happened).....
if it's to the point where MOST people think they need to use a "magic cleaner" then it's usually too late.....
