| x740 Mr. Walker. c. Mr. de Pont. c. Mr. c. Hs.{Lord Ernest Hives - Chair} LUBRICATION. For the chassis engine, in future, we recommend that we change the oil in the crankcase as follows:- After First 500 miles. After Second 500 miles. Beyond this period, the oil should be emptied out of the crankcase and renewed every 2000 miles completed. BY.{R.W. Bailey - Chief Engineer} By | ||
