When mine (built in November/December 2012) got its first service at two weeks old, Revolutions (or RPM as they were then) changed the bevel box oil. When I expressed mild surprise at this as I thought this would be an infrequent event they said that they had been told by the factory that it was a good idea to change it at all services.

Could be a reason for low mileage boxes failing perhaps. Churn the oil and the additive up together then leave it to sit and coagulate.
