Dick & Co. are sending to us a lubricating Oil which they recommend for our engine which contains 25% Lard Oil. The price of this oil will be about 5s. 9d. per gallon compared with 9s. 3d. for Castrol and 4s. 11d. for Prices' Oil. We think it would be worth our while giving this oil a good test because we have found that this firm have supplied us with good oils. Attached herewith is a copy of letter from W.B. Dick & Co. We also attach herewith a R.A.R. Report comparing Prices' Vacuum, and Castrol 'R' Oils. It will be seen that from this, Prices' Oil is 95 to 96% mineral oil. EH.
