The invention relates to the field of material testing, particularly for estimating and comparing the lubricating ability of different lubricants. The device for determining the lubricating ability of lubricants comprises a holder (1) for fixation of a lubricant probe (2), a loading device with an indentor (3) and a diamond pyramid. The device additionally contains a control unit (4) of the load to the indentor (3), a unit for monitoring (5) the pyramid depth sinking into the probe (2), a unit (6) of longitudinal and transversal step-by-step displacement of the holder (1) with the probe (2), a unit (7) for application and change of the lubricants, a calculation-regulation unit (8), functioning according to a preset program, recorded on an information medium, made with the possibility of subsequent automatic read-out and transformation of information into calculation and control signals.
