0w-20 Pennzoil Ultra Platinum or Valvoline Advanced if that is unavailable. They both have some of the best UOAs I've seen for $35/gal or lower. Regular Pennzoil Plat is good and is what I ran before, but Valvoline Advanced has a better addpack IMO.
So, PPUP > VA > PP for me.
(I run boutique oils in my Supra however, and those are either 5w-40 Amsoil Signature or Redline. This is because that has a built motor and puts up with a ton of heat and stress .)
