There are lots of good oils. Eneos, RP, Amsoil & the ultimate Redline are all good. Personally I use Eneos 0w50 in my Supra because it has given me better oil pressure and temps than anything else, but thats my case. I believe you need to experiment to see what works best in your particular situation with your particular engine and setup. If you decide to roll w/ Eneos or Royal Purple PM me as I'm sure you'll be pleasantly surprised at our oil prices
