Are your bearing clearances on the loose side for the 20-50? If not, 50 weight oil robs power.
I don't know the answer to this question. I'm using what was recommended to me by the shop who did my engine rebuild. It's not a race car, I don't drive it much faster than 75mph on the highway, I'm not squealing tire all over the place either. The engine seems to run fine and has all the power I need. But I'll ask the question, thanks!
