more like 5.1 L . Mine takes 5.3 quarts to get it to max with new filter oem.
5quarts is only at the L mark on the stick.
on my non turbo 5quarts is little bit above the middle between L and H.
go figure why the manual says different.

5.1 is right at the middle, which is ok.

5.1qts puts me right between the L and H. it then stays there for the remainder of the OCI.

You simply won't convince me I am hurting my engine by doing 7500 or even 10K oil changes per manufacturer.
I don't believe any of the BS conspiracy theory that car companies don't care what happens to your car after the warranty. That they don't care if cars don't last these days. They learned what happens if you build 'disposable' cars. People still won't buy "American cars" because of the crap they built in the 80s.
You also cannot convince me that motor oils and engine technology hasn't advanced significantly since 1950 when the 3,000 mile OCI was invented in the USA.
Why is that a USA thing?

Oils have improved considerably, however, in the modern era of positive crankcase ventilation and direct injection, that pushes in the other direction. I've seen enough engine tear downs to avoid 10k OCI. I think 5k is perfect, especially with the turbo, and would only push 7.5k if I were a highway commuter.

Ok, well, I guess there's no point in trying to convince you of anything is there. Your mind is made up.
For everyone else out there, engines have evolved a long way from the 1950's, and in some respects, not necessarily in a good way. These small displacement 4 cyl turbo engines, putting out over 200 HP, need fresh oil more often than you think. The tolerances are much tighter to begin with, so any kind of contaminants or sludge can destroy them. Then there's the turbo of course, which needs good clean oil. Lastly is the matter of the direct injection technology that's used now. It is a known problem that these engines all suffer from oil dilution to some degree. Some are worse than others (hello Honda 1.5L turbo). Coupled with the watered down oil viscosity (0W20, or worse), now in use, oil dilution is a real problem. I'll gladly stick with frequent oil changes versus running my cars out. I actually don't drive that much anymore (retired), so I do mine once a year. My DD does about 5,000 kms a year (3,500 miles), and my other car does about 3,000 kms a year. The cost doesn't bother me either.
It's a small price to pay.
My references were always to the point of keeping a car past the 200k or even 300k mile mark. Are you hurting your engine at your miles? Meh, maybe not, only thing that'll tell you that is a tear down which isn't really warranted. Carry on.
This video is for the CX90 but he mentions the CX5 turbos that were blowing up a couple of years back. Mazda's fix was 5W30 oil full synthetic. Go to around the 32 minute segment where he mentions the turbos clogging up due to coagulation. As far as 5000 miles between oil changes oils oil changes are cheap. Engines are expensive. As far a warranty replacement you better have records indication a full synthetic oil change every 5k or else your paying for that replacement engine.
I tried to switch to a synthetic blend a couple years back but the car started to have a burnt oil smell. There were no leaks just this pervasive smell. I switched back and the smell went away.
I put 5W30 full synthetic in all my vehicles including my CX90. I have a 2019 Sorento EXV6 and a 2021 Seltos 2.5IL4. It's bad enough I have to stock three different oil filters, three different air intake filters and three different cabin filters. The 5W30 also goes into my Sears snow thrower, my Snapper lawnmower and my Ariens edger. I have been doing this for years. My local Mazda puts in 5W30 unless the customer requests 0W20.

For the CX-5 and CX-9 turbo engines, Mazda has never (and currently still doesn't) require or even recommend full synthetic. As far as I know, there are no TSBs or anything of the like instructing techs to switch to full synthetic to solve "turbo issues".
I do agree that 5W-30 full synthetic should always be used in these engines. Just wanted to clarify some potential misinformation.
Thanks for the correction. This is the kit I purchased from my local Mazda dealer. While not mandated full synthetic is what Mazda is supplying. I assume that is at least acceptable. I am going to ask my local dealer next time I bring in my car.
My wife commented on the dirty finger nails and the lack of gloves LOL.
