Hi all, I don't live in the US and there's not much of a variety here. There are 3 available fuel injection cleaner additives which are 3M Complete Fuel System Cleaner 473ml, Liqui Moly Injection Cleaner 300ml, WURTH PETROL INJECTION CLEANER 300ml. The ones from 3M and WURTH are recommended to be added in every 5,000km, while the Liqui Moly one is at every 2,000km. Could you kindly tell me which of these 3 is best for the job? much appreciated.

What is your vehicle suffering from?
My car is quite new, it's a Tucson 2021 2.0 with only 10,000km ODO. I asked because I want to use fuel injection cleaner regularly to keep injection clean as part of my self car maintenance 😊
Well, the intervals they suggest is too often. I'm with @itwt, what symptoms do you have that you want to resolve with fuel injector additives.

You don't need to. Instead, You better install an oil catch can for your engine but before doing it, check to see if it does affect your powertrain warranty or not.

Just use good quality fuel instead..
On a 2021 with 6,250 miles there’s nothing to clean. At best it’ll do nothing, at worst these solvents will chew away at your brand new injectors.
Also you typically need injector cleaning on GDi and most Hyundai 2.0L engines are MPi so - no need for it in the first place.
But if you’re 300% sure you want to waste your money on snake oil and can’t help it -
most Hyundai-Kia manuals recommend fuel system cleaner additives (once every 30k or something like that)
But just know that you’re throwing your money away you’ll junk the car way before you should even think about injectors getting clogged on a Hyundai.
If you want to service your car better? Replace the sparks earlier than recommended (let’s say 60k km instead of 90k or something like that), replace other consumables earlier, but injector cleaning? On an MPi? From a company where their injectors that don’t clog anyway?
Thank you, I found you response much helpful. I guess I'm just too paranoid in keeping my engine long-lasting. Just wondered, in terms of regular oil change, which one would you recommend me to use out of these 2: Shell Helix Ultra or Mobil 1 extended performance (gold label) as they cost the same in my country? Much appreciated
IMO the Shell Helix Ultra (if available in the correct spec) is a better choice.
The Mobil1 oil talks about "guaranteed protection for 20,000 miles" and that's absolute snake oil,
the Shell Helix Ultra at least talks about what they deliver ("Protection against LISP", "Excellent turbocharger protection", etc. - both these aren't relevant on a 2.0MPi) and they show how they verified the results.

These engines last 150k miles, the main issue is that some seize at low millage (and there's not much that you can do about it, it's how the engine was built), and engine electronics breaking glitching showing check engine lights - the main thing to have in mind is the typical issue of the Nu-engine - the cat falls apart and pieces of it scratch up the cylinder walls causing oil consumption, compression loss, and engine death. (And here again, not much that you can do)
I bought my diesel Lexus IS220D 2006 58,000 miles about a year and a half ago. I was getting 35mpg and it was rated for 50. I used Toyota's fuel cleaner once, but I still haven't changed the fuel filter so didn't want to cause any problems by dislodging crap.
I used 500ml on a quarter tank (took Scotty's advice about low fuel tanks with crap in them) and got 45 MPG agter a week or so. A year later I'm up to 50mpg and haven't used any since and still haven't changed the filter or cleaned the nozzels.
I've done nothing but 5000 miles of motorway driving and kept the revs low. As until I change the fuel filter I'm not sure if it's losing power at higher speeds/revs.
