Use top tier gas, add a dose of Marvel Mystery Oil to the gas tank every couple of thousand miles and add a bottle of Techron to the tank about 500 miles before each oil change. The amount of money spent is about like a couple of fast food meals so pretty negligible. What is a waste of money is letting a dealer do an expensive "fuel injector flush & service" when doing the steps above will keep the injectors clean.
I haven't had my CX 5 long enough to see if there are any issues with the float in the fuel tank that measures the level giving flaky readings, but in my past 370Z it was a known problem. The addition of a few ounces of Marvel Mystery Oil to the tank apparently had some type of lubricant or solvent qualities that would solve the erratic readings for a couple thousand miles until it came up again. So it isn't just snake oil.

so why the manual states using fuel cleaners only in target countries?is the skyactive engine sensitive to fuel additives?

Techron to the gas tank before every oil change? no Thanks.
I'd rather have the fast food meal, it will do more good. Dammit, Chic-Fil-A is closed on Sundays. Guess I'll keep the money for something way more useful.

Lucas fuel treatment every 2500 miles and Techron 500 miles before oil change. Don't rant without first trying.
Why 500 miles before oil change?

Mazda needs to poach a couple of their marketing guys.

No need to spend hundreds to blast nuts into skyactiv Mazda engines. See Felix Dan's video of DIY cleaning. That said, we just do long daily commutes so not needed for us.

Techron is a solvent. If there is the possibility of of oil dilution I dump the oil soon there after.

Too bad the solvents in Techron aren't strong enough to actually do anything.

Allow me.. "I know what the fuel cleaner doesn't clean on a DI engine. Carbon build-up was so bad on my previous car that I would have needed to get the intake valves walnut-blasted to clean them. I'm asking why Mazda forbids using fuel cleaner in the manual for my current car. Thanks."
To answer OP's question, I think its just CYA on Mazda's part.
