Engine oil MOTUL or IDEMITSU

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

I have a 17 grand touring and I use idemitsu 0w/20 and purolator b9ss filters.

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 in my built engine (not IAG) per the recommendation of the shop that built it.

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

motul 8100 is defenetelly worst oil you can use.
