which oil should i be running?

10 psi per 1000rpm is the formula needed. You don't need more than that. Higher viscosity helps cushion loose tolerances for things that need it, like diesel crank journals and high heat turbochargers that beat the viscosity down to water. Lower oil pressure numbers help lower temp because they increase flow, which helps cool the part.

You should be ok. A lot of people bank way too hard on high oil pressure = good oiling.
