Since SB-LWS-2025-07 our gearboxes use Proseware PWG 220 (ISO VG 220) instead of PWG 320
410 L per gearbox; 60 L flush during the conversion
Minimum oil temperature for start-up: +5 °C (it was +10 °C with PWG 320)
Never mix oils: top up with PWG 220 only

Speaker notes
The conversion campaign runs from September to November 2025 (MOC-2025-012).
