RT6 5w-40 is noy SN rated anymore... if OP has no more cats, it wouldn't matter and RT6 5w-40 would be a good option. If OP still has cats, RT6 multi vehicle 5w-30 might be a good option, it is SN rated and very thick for a 30 grade (12.1 cst @ 100c).
I currently have RT6 MV in my FA20DIT engine and boy, it is one smooth and quiet running engine.
