PETROL FROM COAL
Messrs. Carless Capel and Leonard, pioneers of motor spirit, have put on the market a new fuel called CarlessCoalene. This is produced by the hydrogenation of coal, and since it is sold at the same price as the other No. 1 spirits, demonstrates conclusively that some proportion at least of the motor fuel consumed in this country can be home.produced.
” Petrol,” incidentally, is the copyright name for fuel marketed by the Carless Company and dates from 1895.
On page 66 of the December issue of MOTOR SPORT, the name ” Pratt’s
Ethyl ” appeared. This should, of course, have read .” Esso Ethyl ” which is the designation of the higher octanevalue fuel which has been on the market since spring, 1935.
R.D.I. Way back in 1920, Mr. H. R. Ricardo, the well-known fuel specialist, produced two special blends of alcohol fuel, known respectively as R.D.1 and R.D.2, which have ever since enjoyed great popularity with racing drivers. For
the last few years, the manufacture of this Disco] fuel had almost been discontinued, but we now learn that ample supplies will be available for next season under the name of Cleveland Ricardo Discol No. 1 and 2. These mixtures are, of course, only .suitable for racing purposes in engines with compression in the neighbourhood of 12 to 1. The well-known Cleveland Discol, already widely used in sports cars and which is marketed by Cleveland Petroleum Products Co. is, of course, a mixture of motor spirit and alcohol. This remains unaltered in quality and is on
aIe in petrol pumps all over the country.
