Text Body: The same results are given below on an oil flow base which illustrates this point. It should be mentioned here that in order to get a true comparison and avoid complications, the extra oil feed to the cylinders of the Silver Ghost(1907 40/50 historic RAC 15,000 miles trial) was disconnected.
