Engine oil OEM Mazda or MOTUL

I've been using Motul 5w40 for years and years with zero complaints.

Motul 300V 15W-50 In my "circle" it is used up to 1200+ HP.

Aside from the sodium levels, which they mentioned they aren’t really worried about but to check my coolant between changes (which I do and I’m not losing any). I feel pretty good about these results!

Motul 7100 10 w50 good after using 4000 km

Motul 7100 4T 10W-50 i use this and it's pretty good

Same motor (same car) and I use 5w30 Motul 8100 X-Clean EFE

Motul 8100 Power 5w40 oil. My shop recommends it, I'm based in NC, Autocross in the summer sucks, but my oil temps drop back around 214 degrees F when I come off the track.

Motul full syntetic 10w40, oem oil filter.

I use Motul V300 5w-40. Expensive oil change but no additive breakdown at 3k changes.

they only say you can do that with their Mazda-branded oil. That stuff tends to be expensive.
