Abstract

Forty-five used automobile engine oils were analyzed with conventional fluorescence techniques as well as synchronous excitation and variable separation synchronous excitation fluorometry. Only two samples were considered to be indistinguishable in this group of samples. The high sensitivity, nondestructiveness, and rapidity of these procedures, coupled with their high discriminating power, make fluorometry a method that can be recommended in forensic oil individualization.
