| W/S. Cx.{Major Len W. Cox - Advertising Manager} from Rm.{William Robotham - Chief Engineer} 1220 Rm{William Robotham - Chief Engineer}11/R.9.7.37. We note some astonishing variations in oil consumptions on the P.III's. As an example:- 3.AZ.38 is doing 599 miles to the gallon, and 3.AZ.22 " " 2369 " " " We should like to get hold of each of these cars in turn to fit one of the new clutch plates, and at the same time take the opportunity of checking oil con- sumption, and, in the case of the car which is bad, improv- ing this.
