Motul 300V 15W-50 In my "circle" it is used up to 1200+ HP.
Brakes are genuinely impressive for this segment. Only real issue I faced was chain wear — once you start maintaining it, it improves. I lube mine with 2T gear oil, works surprisingly well. Used Motul for most services, but the last one was with Prolube and the bike feels a bit rougher since then.
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.
I've been running the Motul RBF 600 in my C7 for track and autocross. I flush once a year. It works fine.
motul 8100 is defenetelly worst oil you can use.
