Engine oil MOTUL or ZIC

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.

Motul is a good oil but i stuck with the OEM stuff when i replaced my clutch

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

Clutch doesn't like the full syn stuff.

Buddy and me have found that the Motul 7100 isnt that great in them (additives appear to fail about 1500 miles as seen with very increased mis-shifts).
