I am very pleased to hear that your experience so far follows my forecasts, that a good and expensive oil like Castrol for lubricating the car is a profitable proposition. I would like to get it introduced and recommended, as quickly as we can with safety be sure there is no definite disadvantage in its use. You will remember that I have always been very definitely against the use of pure mineral oil for proper lubrication. R. {Sir Henry Royce} | ||
