It's one of my favorite RL oil grades although I haven't used that particular grade.
My RL source in my area will only sell me a case since it's not a high demand grade in his speed shop.
It has about the same viscosity characteristics as as Mobil Delvac 1 ESP 0W-40.
If you were going to try it just for the fun of it I'd thin it out with 20% TGMO 0W-20. This will give you a lighter 0W-40 with a higher 195 VI and a more appropriate ZDDP level.
