| Mr. Lidsey. from Hs.{Lord Ernest Hives - Chair} X8980 Hs{Lord Ernest Hives - Chair}/LG9.3.25. EAC. - OIL CONSUMPTION. We should like you to carry out tests on 98-NK car in connection with the excessive oil consumption. For one day, the car should be driven at a speed not exceeding 45 m.p.h. - another day, not exceeding 60 m.p.h. so that a comparison can be made with the consumptions when the car is driven all out. We should like you to remove the middle valve in the relief valve unit, so as to reduce the amount of oil to the rockers. You should see that the rockers are getting sufficient oil.
