Hancock - Head Chateauroux} from Hs.{Lord Ernest Hives - Chair} We have received your wire stating that the oil consumption for the first 500 miles run was 286 m.p.g. We have wired you today to carry out tests at various maximum speeds. You will remember we spoke about this before you left. We suggest you might also carry out a test by leaving the oil filler off so as to increase the ventilation of the crankcase. Hs.{Lord Ernest Hives - Chair} | ||
