Cox - Advertising Manager}14/KW16.12.35. You asked me to let you know what sort of oil consumption this car was showing, and I am informed that it is doing between 1900 and 2000 m.p.g. This seems extraordinarily economical to me, but possibly it is no more than you expected. It is very different of course from the consumption of oil of the car on test in France. Cx.{Major Len W.
