TEp-15
GOST 23652-79
Oil TEP-15 is produced on the basis of aromatic residues and distillate oils. The functional properties of the oil are improved by the introduction of anti-wear and depressant additives.
It is used as all-season transmission oil for tractors and other agricultural machines in areas with a temperate climate. Operating temperature range of oil TEP-15-from -20 to +100°C.
