3.4 The performances of the oxidized oil samples
Since the kinematic viscosity of the oxidized 928 and 50-1-4Ф aviation lubrication oils shows small variation (Figure 9s) that could be considered within the margin of error of Ukrainian-style viscometer applied in this paper. However, the kinematic viscosity of the oxidized 928 oil samples has higher values (~4 mm2/s) compared with the oxidized 50-1-4Ф oil samples (~3 mm2/s).
