Howdy folks.  Long time Starion appreciator, first time owner.  I cut my teeth on AWD DSMs in my youth and always wanted a widebody starion but could never seem to find one worth buying.  This 88 Popped up recently and I couldn't help myself, so it's going on the project pile 🤣.

I've seen all the posts that mention running 20w-50 in passing but there seems to be some people that caution against it.

Does anyone have any experience running a 20w-50 or even vr1 specifically?
