I've only started the car three times since I took delivery in early January. I do not remember hearing any unusual noises the first time, although I suppose it could have been present but quieter. The second time (about a week ago), it was as bad as it is now.


About 7 1/2 quarts, plus a half quart of MMO, plus maybe 1/2 pint in the oil filter, which I pre-filled before installing. I did not drain the oil cooler. I used inexpensive 10W30, as I never planed to have the car on the road before switching to Amsoil 10W30.

I'd throw in the full quart of MMO, let run thru fan kick on. Shut it down. Start it up again once weather gets to 35-40F. I run 10W-40 in my car, but do not start it in winter until temps are at least above freezing and preferably ~40F+.
