Its 12.8 @40 and viscosity index of 378 are the best combined performance numbers of any oil I could find. Air gap, the WP4357 range is 130 to 150 mm. With the shortening of CCM, probably better to be 140mm which is also what was recommended at the CCM forums. 140mm air gap = 450ml oil in each leg.
