Any comments?

Looks to be an excellent report. Still break-in going on but excellent at these low hours. I am a little surprized at the aluminum but it is going in the right direction.

There is a difference in the yellow and black bottles. Can't believe how much stouter the yellow bottle additive package is. Didn't we decide this oil was Citgo? Can't wait to see the Amsoil ASE UOA. I'll have the helicopter fly over Benjamming's yard and fertilize it while he's at work. Maybe a little extra watering. A few thousand gallons of Miracle Grow should speed things up rather quickly. We'll have that ASE analysis in no time!
