| To CJ. from EH. X.53 EH8/LG7.2.19. 7th. Feb. 1919. With reference to attached:- Item 2. There is no danger of freezing when a mixture of 80% petrol and 20% benzole is used but there is a danger of freezing if all benzole is used. Item 3. The variation necessary on the mixture control between a mixture of 80% petrol and 20% benzole and all petrol is 1 notch; on the mixture lever we have 5 notches each side the central position. We think that a leaflet should be sent to all our customers explaining the use and advantages of benzole and benzole mixtures. It appears by the papers that benzole is to be freed from control and that no licence will be required to purchase benzole. This being the case a number of customers may wish to run their cars on all benzole or some large percentage of benzole. How to get the best results with these fuels on a R.R. car can be all explained in this leaflet. EH. | ||
