Several catalytic hydrogen‐tritium exchange procedures have been investigated in order to accomplish uniform and random incorporation of tritium into the diverse organic components present in two engine oil basestocks. The most successful procedure involved the use of Raney nickel and tritiated water at elevated temperatures. Comparative proton and tritium nuclear magnetic resonance spectroscopy shows that the incorporated tritium was representative of the organic components present in the basestocks. Comparative gas‐ and radio‐gas chromatography studies provided supplementary information. These investigations demonstrate that engine oils can be satisfactorily labelled with tritium for studies of engine oil consumption.
