What we need is a breakdown of engine types (ALH, BEW, BRM, CBEA, CJAA), further broken down by oil type, miles on engine, and then evaluated by ppm/1000km. All of this comparing of different oils in ppm (over how many km!!?) across all engines is pointless. A far more detailed analysis is required and we need far more participants.
