X1583 X967 We are not at all satisfied with some of the recent results we have obtained with Prices Oil. There have been cases of failure which we consider have been due to this oil. Because of the dissatisfaction with Prices Oil we are running experimental cars with different oils and our tests so far show that either Duckhams or Wakefields oil are better than Prices. We have arranged that when we have three cars running in France under similar conditions we shall make comparisons with different oils. We think it would be unwise to bind ourselves to using Prices Oil. Where customers have enquired, we have told them that in our opinion the Rolls-Royce car will behave satisfactorily on Duckhams Oil.
