Alright, after talking to 3 distributors and two Oil Companies, I found that we can get Brad Penn right here in Calgary.
Classic Performance stocks it, and I spoke to Carmine there and they can always order more

They currently have 20/50, 10/30, and others. It is the Racing grade partial synthetic. I asked him about the non-dino component and he said they haven't had any gasket leaking issues on their old big iron cars.
They are open on "some" Saturdays so call first, otherwise 9-6 weekdays.
