CHASSIS INSTRUCTION BOOK, AND USE OF BENZOL. X.2538 With reference to your memo. Bn{W.O. Bentley / Mr Barrington}/Wl/Ck{Mr Clark}4.2.20, in recommending the use of Benzol mixture, I do not think that at any time we should exceed 25%. Also, I do not think that the mixing of the Benzol with the petrol should be recommended unless the petrol is of an inferior quality. We should at the same time take advantage of recommending them to use the best quality of spirit. If Aviation Spirit is used, Benzol should certainly not be used. If an ordinary good spirit is used, such as best Motor Spirit, Shell, Mex, or Pratt's, no benzol should be used, but with a spirit which is not up to this quality, we recommend 25% Benzol. I should like this point to be confirmed by Hs.{Lord Ernest Hives - Chair} EP.{G. Eric Platford - Chief Quality Engineer} | ||
