OIL CHANGE + 1800

I recently had a lot of trouble with an overdrive in a rallying PV 544, basically because we couln't stop it from disengaging when really caning it. This on a PV with a 4.8 rear diff and LSD.

I had a long conversation with an oil expert in the technical department of Millers oil. He told me that the multigrade part of engine oil is a polymer. Whilst it copes very well with its designed use, in an engine, it does not cope well with the extreme pressures in a gearbox. We now use some really weird high viscosity Hypoid oil in the D type overdrive, and it works a treat.

I agree though that in npormal use the overdrives are not very fussy, and tend to throw in whatever comes to hand.

Regards

Pete
