I would agree with Rekluse but sometimes you have issues on the weekend or you can only work on your bike on the weekends so it makes it hard to always talk to them...
You can run Rotella T6 full synthetic with the Core EXP products without a problem. It's what I would recommend for protection and better cold weather starting.
Yes Rotella T6 full synthetic is great oil I am on my 3rd year using this and it has been working great with and without the Rekluse core exp. 2012 KTM 500 EXC. 2015 Husky FE 501
