driving below 2800 RPM = trouble?

I am open but skeptical!

Hey Brucelee, I just watched Enter the Dragon a few days ago on TV, it never gets old. You really can't lug the engine if it is in auto mode, but if you are in manual mode and you are in 4th gear and have to slow down due to traffic, etc. and don't downshift manually, you can definitely lug the engine in that scenario.

If I've understood Jake Raby and Charles Navarro's comments correctly, the higher rpm translates to higher oil pressure which feeds the IMS bearings at a greater volume, reducing friction (I know, the bearing is supposed to be sealed, but likely leaks).

This is also why they recommend removing the outer seal to allow greater oil flow.

And for what it's worth, I only use Royal Purple in my Box S. Tried it in my '73 911, but leaked too much; so back to good 'ol 20W50 Castrol GTX Dino juice (though it's looks like Brad Penn going forward).
