Transmission oil TAD-17i

Oil TAD-17i (TM-5-18) (GOST 23652-79) - universal all-season mineral oil. It contains multifunctional sulfur-phosphorus additive, depressant and antifoam additives. The oil operates within the temperature range from - 25°С to +130-140°C.

The composition of additives improves extreme pressure, antiwear, antifoam, antioxidant, anticorrosive properties.

Transmission oil TSP-10 (TM-3-9) is used as an all-season oil in the Northern regions and as a winter oil in temperate climate region at contact stresses up to 1500-2000 MPa and oil temperatures up to 100-110 ° C. TSP-10 oil is included in the TM-3 group of oils produced in accordance with GOST 23652-79. The letter C in the marking means that the oil is obtained from sulphurous oil, letters P - oil with additives. The oil change interval TSP-10 (TM-3-9) is 35000 - 50000 km. In winter, in the absence of TSp-10 oil, it is allowed to use a mixture of Tap-15V or TSp-15k oil with 10-20% diesel winter or arctic fuel. It maintains its properties at temperatures up to -40, -50°C.
