Engine oil MOTUL or Motorcraft

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

If it’s actually an IAG long block, they spec Motul 8100 X-CESS 5W-40 (or an equivalent high quality 5W-40 full synthetic) because their bearing clearances are set up for that weight, not the thinner OEM oil.

I run 10w40 5100 motul now. on all bikes etc.

Clutch doesn't like the full syn stuff.

motul 8100 is defenetelly worst oil you can use.
