For those who run it, just curious of the feedback, to ask please:

Previously, I have used the Brad Penn/ Penn Grade1 and the VR1 straight 40w (VR1 had better pressure readings vs the Penn Grade1), but have thought about the above. It says their additives can be used:

For those who run with both, any pros, cons, etc.? Thank you for your time and info,

I don't see any issue using it but I question the additive unless you are trying to increase oil pressure on a thinner oil but not wanting to change it yet.
I have used Lucas,Valvoline VR1, and Castrol formulated for older engines. No problem with any.
