One more note about the Amsoil…
It is GOOD on COLD shifts! First to second is no problem, even when cold.
Feels better than whatever was in there before, most likely Porsche stuff. Very good on HOT days too! Have not missed a shift since I have run this stuff. It seems to "slide" into gear easier. At a stop the gearshift moves with little effort (NOTE: that may be more indicative of gear wear than actual lubrication however).
We'll see how it looks when I have to replace it in another 60k miles!
@JD - can you get that oil by the liter?
