In addition I have to wonder if the oil pump belt is compatable with diesel fuel and the various bio diesel blends.
Is the belt lubricated by engine oil and fuel??
It is lubricated by the engine oil, but will be exposed to some diesel fuel as well from the regen process since GM didn't include a external 7th injector. Instead they went with the regen process by dumping diesel fuel into the cylinders on the exhaust stroke which means some % of diesel fuel will get into the crankcase.
