Add to the fact that, if it were the oil that was breaking down prematurely, other components (bearings, can lobes, cylinder walls) would be damaged too. I assume that isn't happening. Until someone can post up a technical reason why this happens, I'm not buying the oil explanation.

Wait a minute, so you guys are saying 9,000 - 10,000 mile oil changes are OK??
That is what the orig monitor let you go.
