The potential role of singlet oxygen in the oxidation, and subsequent degradation, of engine oils was investigated using spectroscopic steady-state and singlet oxygen lifetime measurements. Three currently commercially available antioxidants; a sterically hindered amine (aminic), a sterically hindered phenol (phenolic) and sulfurized olefin, all provided by Lubrizol, were tested alongside previously documented singlet oxygen quenchers; α-tocopherol and squalene.
