Engine oil specification for W214 E53




According to this 223.2 Engine Oil table, cars equipped with the M256 Hybrid engine use oil specification 229.51 or 229.52.
https://operatingfluids.mercedes-benz.com/sheet/223.2
There are three entries for the M256 engine in this table.
1) M256.9 except Hybrid, oil spec 229.51, 229.52, 229.61, 229.71, and 229.72
2) M256 Hybrid, oil spec 229.51 and 229.52
3) M256.8 except Hybrid, oil spec 229.71 and 229.72
According to the online digital manual the E53 should use 0w-40 or 5w-40 oil but the actual oil quality is not specified.

I plan to change the oil in another 3000 miles and I am hoping to get some clarification on the oil type for the E53 beforehand.
Where can I find the full engine number for the E53 Hybrid?
Should I use oil meeting the 229.51 spec for the E53 Hybrid?

This... https://www.mobil.com/en-cn/passenge...ultimate-0w-40 meets both .51 and .52 per the MB operating fluids spec and would be my choice for my oil change in 6 months.
Also helpful is the attachment.

ESP X4 speaks to the partnership with Porsche in the development of the oil, 4120 speaks to being specially adapted to the requirements of Mercedes-Benz vehicles. I ultimately went with Liqui-Moly 1950 for the GLC300 725.058 trans flush as the 1950 was specifically formulated for the MB 725 trans.
The 4120 is new - still searching for availability.

The digital owner's manual for the CLE53 with the same 256.830 engine as the E53 specifies the viscosity as 0W-20 and the quality as 229.71 or 229.72. It also shows the capacity as 8.5 quarts. Why is viscosity, quality, and quantity different than the 2025 E53?
How do we know with certainty that the oil quality for the E53 is 229.51 or 229.52 and the capacity is 10.5 quarts? Is there any document other than the 223.2 Engine Oil table that provides a definitive oil specification for the E53 Hybrid?

I'm also giving a gentle nudge to our Liqui Moly contacts regarding the 4120.
I appreciate everyone here with the E53 who is attempting to solve the painful lack of information through various adaptations of the manual.
