5w40, and the start up clatter is much better. It hasn't gone away completely, but I'd say its 80% better.

I tried many types of oil, from M1 0w40, M1 15-50, Castrol 5w40, valvoline 20-50 and there was no difference in start up clatter.

I think I'll stick with Redline. Its expensive, but when you look at it the difference in cost is about the cost of a tank of gas.
