Oil T-22 (GOST 32-74) is made of high-quality, low-sulfur, non-paraffinic oils using acid treatment. Does not contain additives. The choice of materials and the optimal refinery yield allow achieving high performance oil properties. Has similar scope of application as Тp-22B and Тp-22S turbine oils.
