I am picking engine oil to run once I drain the break in SAE30, my engine is on the loose side and so is the oil pressure, but I got plenty of flow given the pump/block galley work, cooler orientation etc

either way I want to run 60 weight oil since my main clearances allow that, and it will bump the pressure a bit

I have ran different high weight racing oils before, mobil, motul, castrol but as I was looking over the different oil lab analysis charts I came across something I haven't seen before - petronas Syntium Racer 10w-60

what got me interested, is that this oil demonstrates higher viscosity index at 100* temps than same class motul, amsoil or millers

there is very little information about this oil available, and I was wondering if anyone has first hand experience with it?
