To keep the thread going, does anybody have a clue HOW the oil gets to the combustion chamber? It has to be thru the rings or valve guides, but why? I'd understand if we were running 5/20 oil, but with 10/60? Aren't our engines supposedly built to very close tolerances? Something doesn't add up.

I'm at 1,600 miles from the break-in service, and oil level still shows as full, which is good news since most of those miles have been highway, at high speeds (between 3,500 and 4K rpm), where this car supposedly burns more oil.

I'm thinking these engines drink more oil when pushed hard, rather than just revved high for highway travel, no? At the ton, it's revving over 4K rpm, but hardly breaking a sweat. And the funny thing is the engine doesn't sound like it's revving high, or even strained at all. Love driving this car on trips; it's a blast. Hope everybody had a great Thanksgiving .
