You've got part of the equation which "flow is good". Pressure is an important part of the equation too.. I'm totally fine with running as thin an oil as possible so long as target pressures are maintained. But if I can't make more than 50psi at 7k rpm with a 20wt oil at my operating temp (280f in your case) then I either need more viscosity or less temp.

What's your oil pressure at 7k rpms when your 30wt is at 280F?
