Vacuum oil VM-5 (OST 38.01402-86) is produced from low-sulfur or sulfurous oils through several stages of fine vacuum distillation, as well as deep purification, ensuring a high class of product purity. It has a higher kinematic viscosity compared to VM-5C oil and is stable to oxidation. The shelf life of VM-5 oil is 5 years from the date of manufacture.
