Mobil Vacuoline™ 500 Series circulation oils
Mobil Vacuoline™ 500 Series are high-performance, heavy-duty circulating oils available in six viscosity grades. They are recommended for use with marine moderate-duty spur, bevel, helical and herringbone gear units. They are also suitable for use in hydraulic systems employing gear, vane, radial and axial piston pumps, where high viscosity anti-wear hydraulic fluids are required.
Potential benefits of Mobil Vacuoline 500 Series oils include:
- Excellent protection of critical bearings and gears
- Resistance to oxidation and thermal degradation, helping give longer oil life
- Lower maintenance and disposal costs, as well as inventory savings
- Rapid water separation, enabling rust and corrosion protection

Applications
These oils are intended primarily for the lubrication of plain bearings, roller bearings, parallel shaft and bevel gearing. They are suitable as multipurpose lubricants in systems not subject to shock loading and which do not require extreme pressure performance. The Mobil Vacuoline 500 series possess good demulsibility that is retained under conditions of severe water contamination. Mobil Vacuoline 500 series are used in applications using splash, bath and ring oil arrangements and all other application methods involving pumps, valves and auxiliary equipment. They are recommended for use in hydraulic systems where higher viscosity oils are specified. They are particularly resistant to the effects of prolonged high temperature exposure and perform well in circulating systems with short oil residence times.
Typical applications include
- No Twist Rod Mills
- Moderate duty spur, bevel, helical and herringbone gear units
- Circulating systems
- Mobil Vacuoline 525, 528, 533 can also be used in hydraulic systems employing gear, vane, radial and axial piston pumps where high viscosity anti-wear hydraulic fluids are required.
- Certain compressors and vacuum pumps handling air and inert gases provided the discharge temperatures do not exceed 150oC , not suitable for breathing air compressors
