TSP-15K oil (GOST 23652-79) is a residual oil with a small addition of distillate oil and a composition of additives that improve extreme pressure, antiwear, low temperature and antifoam properties. It is used for the gearbox and main transmission (two-stage reducer with cylindrical and spiral-bevel gears) of KAMAZ vehicles and other trucks. TSP-15K oil retains its properties for a long time within the temperature range from -20 to + 130°С.
