2001 S600 can use any of these:
Mobil 1 SuperSyn European Car Formula 0W-40
Castrol Syntec European Formula 0W-30*
Pennzoil European Formula Ultra 5W-30*
Quaker State European Formula Ultra 5W-30*
ELF Excellium 229.5 5W-30*
Mobil 1 ESP Formula M 5W-40

Mobil 1 SuperSyn European Car Formula 0W-40
Castrol Syntec 5W-40
ELF Excellium LDX 5W-40
ELF Excellium LDX 0W-30*
Quaker State Full Synthetic European Formula 5W-40
Pennzoil Synthetic European Formula 5W-40
76 Pure Synthetic Motor Oil 5W-40
Kendall GT-1 Full Synthetic Motor Oil 5W-40
Motul 8100 E-Tech 0W-40
Motul 8100 X-Cess 5W-40
Shell Helix Ultra 5W-30*
Shell Helix Ultra 5W-40
Valvoline SynPower MXL 0W-30*

The *s are oils that you can't use in AMG models.

The 2005 and later approved list is much shorter:
Mobil 1 SuperSyn European Car Formula 0W-40
Castrol Syntec European Formula 0W-30*
Pennzoil European Formula Ultra 5W-30*
Quaker State European Formula Ultra 5W-30*
ELF Excellium 229.5 5W-30*
Mobil 1 ESP Formula M 5W-40 (mandatory for Bluetec with urea)
Valvoline SynPower MST 5W-30*
