Well, your hear a bunch of options.
I would hit up Jackson Racing customer service, and ask them what they would recommend.
I'm pretty sure that's the best way to go. Other wise everyone and their mother will tell you to put X brand and X weight.

I would stick to the factory oil spec till you hear from them.

Also FYI Motul isn't all that. Just a different oil brand. Nike vs. Reebok. Which fanboy base do you want to be in?
I'm a Mobil 1 fanboy, reason: Walmart cheap, find it anywhere 24/7 7 days a week. Even in the middle of bumfuck vile.
Other brands like Motul. Special order, wait a few days a bit pricey. For same exact performance.
