| E.P. To Hoy. from Hs.{Lord Ernest Hives - Chair} Y985 Hs{Lord Ernest Hives - Chair}3/LG6.7.25. POWER PETROL. With reference to the attached correspondence and leaflet in connection with the above. We have never carried out any definite tests with power petrol. We have previously seen the results of the R.A.C. tests, but we were not impressed by the figures obtained. The method of driving the car during the trial makes it impossible to compare the results with normal driving. We can obtain astonishing petrol consumptions on our own car with any reasonable fuel, if we set out with that one object in view. From the analysis of power petrol given in the certificate, we should say that it would be a satisfactory fuel to use on our 20 HP. cars. We doubt very much whether it will give any different results to the usual fuels xxxxxx purchased at Garages. Hs.{Lord Ernest Hives - Chair} | ||
