Motul 7100 10 w50 good after using 4000 km
Motul 7100 4T 10W-50 i use this and it's pretty good
The interesting part is that the T6 was used to tow a camper from Indiana to the Oregon coast where we are now. It’s interesting to see the viscosity, flashpoint and Moly are higher in the T6 even after towing through the mountains and more miles on the change.
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.
This sub loves to praise motul, but it caused me to foul up my spark plugs and have misfires. I tried both the 5W30 like the manual calls for and 5W40, but shortly after I changed to motul my plugs fouled up. I replaced them, they fouled up and misfired again. I tried it a third time cleaning the MAF sensor, checking if the plugs were torqued okay, checking the seal on the coil packs, etc... still fouled up. I finally guessed it was the motul and did an oil change away from motul and swapped the plugs again. 14k later no fouling.
