     Densities of a number of oil-test portions are tabulated according to their viscosities and their origins from cracked gasoline or from circulated gasoline.  Their relations are represented graphically.  Because of the large variation in the values, these curves do not have the significance of a functional relation but only of a correlation.  As a rule, the densities of oils from cracked gasoline are higher than those of oils from circulated gasoline.  Generally, density increases with increasing viscosity.  1 graph.
