Definitely it’s different factory-fill on the 2.5T from the 2.5L NA based on totally different molybdenum content.Factory fill oil - Used oil analysis from CX5 2.5T 2022. No idea what Oil Mazda fills in the factory.

No comments from this Blackstone Lab UOA report?Yes the 2.5 NA Mazda oem moly oil is great oil but unfortunately no such good fully syn oil is sold for the 2.5T by Mazda in NA. The oem 5w30 is not good and I think I heard its not even full syn.
The almost non existing Boron in this UOA and the crappy viscosity at such low miles makes me wonder if this factory fill is even full synthetic 5w30. Anyway the oil is gone and next Uoa would be for Amsoil XL 5w30.
Oil Analyzers use Horizon labs, so it is not exactly under the Amsoil umbrella. And I never noticed any bias towards Amsoil in dozens of reports I got over years from couple of labs.Looking to get a second lab report to compare to Blackstone . Seems alot like labone and Dyson went out of business. Is Oil Analyzer (Amsoil) any good? Are their results skewed toward their oil?
Any other labs?
I dunno:is it possible they overfilled? our engines ususlly will burn the extra oil if above the top mark.
Usually DIY but took it in for a few repairs before B2B expired and offered to do the oil change at minimal cost. Yep it was minimal all right.dont go to the dealer or ask them to put mazda moly. Costs more though. Or best is DIY
post the analysis when you can. It would be interesting.
Any particular reason you switched the oil from Mazda genuine SkyActiv-D SAE 0W-30 diesel engine oil to Mobil 1 ESP 0W-30 motor oil? Any differences on oil consumption and fuel economy between the two?Latest UOA is back on the diesel. Right at 3 years in now with 67500 miles. All is well and cool runnin'

No difference for consumption (none on either) or fuel economy.Any particular reason you switched the oil from Mazda genuine SkyActiv-D SAE 0W-30 diesel engine oil to Mobil 1 ESP 0W-30 motor oil? Any differences on oil consumption and fuel economy between the two?
Can you tell if Mazda genuine SkyActiv-D SAE 0W-30 diesel engine oil is also made by Idemitsu like Mazda’s 0W-20 Moly oil?No difference for consumption (none on either) or fuel economy.
Mazda included maintenance for the first 30k miles with the vehicle purchase. I bought a case (12 quarts) of the SkyActiv-D 0w30 diesel engine oil early on just to have on my shelf to insure availability when I needed an included service. There was twice during the first 30k miles that my Mazda dealer didn't have the oil and used mine (replacing my stock later).
Because I saw supply issues with the Mazda oil, I sought out an alternative to have and settled on the Mobil1 0w30 ESP and found it for a similar price to the Mazda oil and bought a case to have on my shelf. After comparing the UOA reports of the Mobil1 and Mazda oil, I'm sticking with the Mobil1. I think it's a better oil, holds viscosity better and the additive package seems to be more robust (evidenced by the higher TBN number).
As a bonus, the Mobil1 0w30 ESP is now available in 5qt jugs for convenience and cost savings (about $35).

Haha! I asked the same question before, sorry ⋯
Yep. Idemitsu Lubricants. (Just down the road a couple of hours in Jeffersonville IN).
Incidentally, I've been in the Idemitsu plant a few times. High quality facility. They run a tight ship there. I'd pick my ice cream cone up off the floor and eat it should it fall . A stark contrast to Valvoline and SOPUS (Shell) plants I have visited.
I have settled on Mobil 1 5W-30 EP in my 2019 CX 5 with the 2.5L Turbo engine. The oil is full synthetic and low on sulfated ash content which supposedly is beneficial for DI engines. I only go 5000 miles between changes however, regardless of Mobil 1's claims that the oil is good for 20,000 miles. I'll get a Blackstone analysis done on the next oil change and post it here.
