I don't know what specific oil is recommended by Morgan but I can tell you that we have had tremendous success with this specifically designed oil, Motul Gearbox, in Moto Guzzi gearboxes and bevel drives. Not only does it do an excellent job of lubrication but also reduces noise and wear, and makes for slicker gear changes. For many years it has been used and recommended by the Agostini dealership in Mandello.
