Per California Motorsports (CMS):
"Oil level needs to be just below the diff center. Just up to the bottom lip of the axle seal. You can remove the axle to verify.
As per your picture, it would be the orange line above the red line. Capacity should be in the neighborhood of 5L."
Using my homemade dip stick, the final correct volume was 5L.
