Get that 30 weight oil as soon as you can and at the least put in a 15w40 diesel oil (Chevron Delo's latest brew is hot stuff) while you make up your mind. Track the pressure while oil is hot at 2k, 3k, 4k, and 5k rpm. Old rule of thumb is you want 10 psi for every 1000 rpm (so 50 psi at 5000 rpm, etc) but with your engine I don't know if that still applies.
