One bottle of STP treats 5 qts. of oil. My system, 7 Qt. pan, windage tray =1 more qt. and an HP oil filter = 1 more qt. That's 9 qts, and I just add another bottle for GP's. You can't have too much zinc. I run a solid lifter cam, with 1.6 roller rockers. I agree that something had to cause the bearing to spin, my question was, why does it usually happen to #6 or #5 rod, mostly #6? And what can be done to prevent it in the future?
