JUNE 25, 1936. ADVERTISEMENTS. FLIGHT. 31 AERO OBILOIL LESS CARBON LESS SLUDGE MORE OIL-MILES PER GALLON The only Aero oil refined by the CLEAROSOL PROCESS Aero Mobiloil is an entirely new lubricant produced by a new process of refining. Hitherto it has proved impossible, by conventional refining methods, to extract entirely the non-lubricating elements which exist in all crude oils. The Clearosol process by which Aero Mobiloil and only Aero Mobiloil is refined removes the tarry, gummy, non-paraffinic compounds by dissolving them away. The desirable characteristics of the oil are retained in the maximum degree, the undesirable elements are rejected. The process effects a purely physical separation of the valuable paraffinic hydro-carbons from the injurious carbon- forming, gummy, asphaltic and non-paraffinic constituents of the crude oils. The separation is obtained by mixing the lubricating oil stocks with two solvents which will not mix with each other. The paraffinic constituents are dissolved in one solvent, the slummy elements are dissolved in the other. The differences in specific gravity render the resulting solutions easy to separate. The process is carried on at normal temperatures and has no chemical action upon the oil. A GREATER Because it consists only of the richest paraffinic fractions, and has not MARGIN OF SAFETY been subjected to the destructive action of acids or extreme heat, Aero Mobiloil is extraordinarily stable in operation. It forms less carbon. It lubricates longer. It doesn't gum. Obtainable everywhere LESS WEAR MORE POWER EXHIBITION SOCIETY OF BRITISH AIRCRAFT CONSTRUCTORS LTD.
