Apologies

That link just tells you what they run.

If using an old clutch you may want to stick with the oil type that this ran in, either semi or full or you may experience slipping issues.

If a new clutch then just pick your prefered choice

For myself I run semi oil but do change it every track day as my turbo blade does turn it much darker after a hammering.

I used Silkolene Pro4 15W-50 in my Busa and still use it in my ZX10. It's what Radical use in their Busa engines. I use the 15W-50 to try to maintain pressure when it's hot but if it was a road car I'd use the standard 10W-40.
