6.0L, 6.3Q is correct with a new OE type Bosch 72165 filter. Other filters may be different.

I usually just install 6.0Q of SAE 15W-40 CK-4 and call it good. I believe the min/max difference is approximately 2.0L, as stated in the owner's manual. If mine gets down halfway in between I add half a quart.

I can't remember the last time the oil level light came on, but I recall it's before the level on the stick reaches the "min" point.
