| -2- The oil pressure is not excessive the maximum pressure reached on the consumption test was 31 lbs/sq.in. although we would only estimate the speed at about 65-70 m.p.h. since the speedometer had been disconnected. The oil pressure on G.A.E. 20 at 70 m.p.g. was 31 lbs/sq.in. The mileage of G.U.L. 59 prior to the consumption test was 378. We have got them working overtime on the job to-night and if necessary they are working through the night in which case we shall do another consumption test at 5-0 a.m. to-morrow.
