Mobil Univis HVI 13
Mobil Univis HVI 13 is part of the Univis HVI Series, a range of premium performance anti-wear hydraulic oils characterised by their unusually high viscosity index. These oils are engineered to maintain close viscosity control across wide temperature ranges, making them suitable for hydraulic systems sensitive to viscosity changes. The formulation delivers reliable lubrication, high efficiency and consistent hydraulic performance in demanding operating conditions.
One of the key advantages of Mobil Univis HVI 13 is its excellent low-temperature fluidity. The very low pour point allows reliable operation in extremely cold environments, supporting fast start-up and responsive hydraulic system performance. This makes it suitable for mobile equipment, cold storage applications and systems operating in sub-zero conditions.
Mobil Univis HVI 13 also provides strong anti-wear protection. The formulation helps protect high-pressure vane, piston and gear pumps, reducing wear and extending equipment life. The oil also maintains viscosity stability under shear conditions, helping reduce internal leakage and improve system efficiency at high temperatures.
Another important benefit is its oxidation stability and cleanliness performance. The oil resists deposit formation and helps maintain clean hydraulic systems. It also provides good water separability, rust protection and corrosion resistance, supporting long service life and reliable operation.
Mobil Univis HVI 13 is recommended for hydraulic systems requiring precise viscosity control over wide temperature ranges. It is suitable for hydrostatic transmissions, fine instruments, servo-valve systems and equipment operating in cold start-up and high-temperature conditions. The oil is particularly useful where high load-carrying capability and anti-wear performance are required.
Physical characteristics include ISO VG 13 viscosity grade with a kinematic viscosity of approximately 13.5 mm²/s at 40°C and 5.3 mm²/s at 100°C. Mobil Univis HVI 13 has a viscosity index of approximately 404 and a pour point of approximately −60°C. The oil provides exceptional viscosity stability, cold temperature performance and reliable hydraulic system protection.
