This is a timely post for me. I have been running 20-50 VR-1 for a long time and my oil pressure was 80lbs hot. I have been trying some 10-30 while the weather is cold and I am not beating on the car as hard.

I believe that the 10-30 is a better choice for the engine. But since I have ran the 20-50 for years with no problems, I have been a bit hesitant to change.

But if it works for Cab, I'm in.

Master, again and still
