Wor.{Arthur Wormald - General Works Manager} OILS - CARS AND AERO ENGINES. Z.1583 X.967 Z.2465 X.1588 REGARDING CAR OILS. I have already approved Wakefields XL. as second standard, but preferred Price's as first favourite. I also suggested finding still another, perhaps a different one for England and France. I suggested we ourselves ran a carbonisation test, and that it might be worth our while to ask Mr. Ricardo to test any oils we first thought possible. Would you like me to see him on my return to WW? I can at present only believe in a correctly compounded oil, really for all purposes of lubrication of plain bearings including the Works machines. REGARDING AERO ENGINE OILS. I explained my views to RG.{Mr Rowledge} that I could not believe it was right for the Air Ministry to insist on running a type test on either entirely castor oil, or an entirely mineral oil, and that some of the recent failures might be due to oil. Here again it might be much cheaper to get Ricardo's views. I would not accept the responsibility of making such a test without some further knowledge, and should advocate shifting the responsibility on to someone else. In fact I should have expected both RG.{Mr Rowledge} and Hs.{Lord Ernest Hives - Chair} to have pushed such responsibility on to em, and I should have sent it on to the Management and contd:- | ||
