Mazda did exactly the same thing by replacing the oil level dipstick with a revised one featuring additional high-water *X* mark above the *Full* mark, during the time trying to resolve the oil rising issue on its SkyActiv-D CX-5 diesels. Owners have to change the oil when oil level reaches to the *X* mark, although this oil dilution issue is caused by DPF regeneration.
I almost feel like Mazda put higher *Full* mark than normal on dipstick to our 2.5L like the high-water mark hence specified 4.8-quart refill and factory oil fill can only reach to ~ below the *Full* mark.
I was concerned because when I added the quart, dipstick level was not much higher than the low dot. I looked up my service notes and realized I misremembered, this was closer to 6k miles on the interval that I added the quart. Not 5, or 5.5k.
Alternatively, thinking of just keeping with the 0w20 and going back to a 5k mile interval.
Edit: Here was the dipstick at 6k miles since last change (5 qts. of Castrol Edge 0w20 on 9/29).
Maybe it's always done this since I only started doing my own services last year, and only really noticed that I only drained a bit over 4 quarts last oil change (because I probably wasn't paying enough attention on the previous change to think about measuring what was drained). But this seems a bit concerning to me, hence why I am trying to figure out the best route for oil for me.
Haven't decided yet if I'm going to give the Mazda Moly or Idemitsu oil a try since they are way more expensive.
Suppose I keep buying a 5 quart jug at Walmart, what's the difference between the regular oil and the ones that say extended mileage or high mileage, or similar? I saw some that were same brand as I've been using (Castrol Edge) but seem to be marketed toward 75k+ mile cars.

That is nearing the "oh crap" low. There might only be 2 quarts in your crank case. Check the oil level every 1K or so. How many miles on your car?

79,800 miles-ish.
This is one reason I like an oil gauge versus an idiot light. You can tell when the oil is getting low versus hitting a critical point. If dash space is at a premium, I'll take an oil pressure gauge over a tachometer any day of the week...especially with an automatic (where a tach has diminished value.)
I don't know what the threshold is for the oil light to come on, or if there is even a standard for it. I don't know why few cars include them.
Regarding the level on that dipstick, the manual says that any place between the marks is fine. Sure, it's the low end of acceptable, but most likely I would think it's close to 4 (meaning a quart low).
I think they didn't update the manual. To change the oil and have it half way to low is crazy. It should be on the full mark after an oil change. My car was on the full mark when it was brand new.

I may go with the Idemitsu moly alternative since IIRC it is speculated they make the oil for Mazda and is quite a bit cheaper.
The high moly Indemitsu oil is usually about the same price as the Mazda oil whenever I check. The Mazda oil is about $43 for 5 qrts online when I've bought it and that's exactly how much the Indemitsu is on Amazon right now but looking at the price history, it has been quite cheaper in the past: https://camelcamelcamel.com/ZEPRO-3...list-Advanced-Fluid_Ounces/product/B072QXMJBS
That is the non-moly formula.
Here is the moly one--->
