Vacuum oil VM-1 (OST 38.01402-86) is produced from low-sulfur or sulfurous oils using several stages of fine vacuum distillation, as well as deep purification, ensuring a high level of product purity. It has a higher kinematic viscosity compared to oil VM-1S and is stable against oxidation. The regulatory documentation does not contain strict requirements regarding the organoleptic properties of oil VM-1.
