I've also used Schaeffer 10W-30 and 15W-40 with great UOA wear results in the past.
This is the way I go.

Mobil 1 5-30 and K&N oil filters. Did my cam swap last week and the timing chain area was as clean as a whistle with 15000 miles on the clock. Couldn't believe how clean the entire engine was from the valve train down.
