The standard oil in a "GV" drummotor is Castrol Alpha SP 100. If the oil needs replacing, it is important that it conforms to ISO VG 100 standards.

For use in the food industry, the drummotor can be filled with Castrol Optileb GT150. This is a synthetic food grade oil.

If the drummotor is fitted with a Wet Brake (recognisable by WB in the type-number) or a Clutch Brake (CB), it will be filled with Castrol Agri-trans plus 10W30. Or, in the food industry, with Castrol Vitalube HS68. Both are synthetic oils.

In low temperature environments (-40°C) the drummotor is filled with Vitalube HS32.

Oil equivalents are mentioned in our manual.
