The aim of this work was the classification of fresh lubricants for forensic science field. The seventy five kinds of lubricants were analyzed three times by GC/MS. And each lubricant (class) had three TIC data. Lubricant database were made with the two TIC data (samples)of all of lubricants. The rest of TIC data were sample (test). The HQI statistical technique was used for classification. The HQI values of samples were calculated from DB. For lubricant classification, when the criterion of identification was 0.95 of HQI value, the rate of matching was 91 %. And when the criterion of identification was 0.90 of HQI value, the rate of matching was 96 %.
