My understanding is Mazda FF usually contains tons of moly. So where's the moly?


 
The UOA looks really good for a fresh engine and thanks for posting. But where is the molybdenum Mazda's OEM motor oil is known for? With the relatively lower calcium and higher magnesium I wonder if this is Idemitsu's Dexos1 Gen 2 formula?

I thought they were using Castrol now.

Well that’s a surprise. Mazda uses Idemitsu for factory fills. Maybe this is that new Zepro with the super advanced moly?
 
Currently using PUP 5w30 and I also stocked up on a quite a bit of it the last two years with the rebates. Now I'm reading about LSPI. Should I continue using PUP or look for something with less calcium?

Current Stash:

40qts - PUP 5w30 both dark silver and yellow bottles
18qts - Edge 5w40 - Kia Optima 2.0T
15qts - PUP 0w40 SRT - Tundra 4.7 1UZ-FE
15qts - PP 5w30 Silver bottle

That’s a tough call. That PUP is pretty good oil. You have quite a haul there. For the new CX-9, I would use one of the new dexos Gen2 oils. Most brands have them now.
 
As PimTac mentions, that is a tough call. The 2.5T may have no LSPI issues but it's just to early to tell. Being such a large vehicle with a proportionately small displacement DIT, i would go with a dexos1Gen2 moving foward. Congrats on vehicle, they're strikingly handsome and should give many miles of reliable motoring.
