The Mobil Vacuoline 1400 Series oils have been developed to provide an extra margin of machinery protection by satisfying the requirements of hydraulic systems while meeting the stringent demands of the ways. Their outstanding oxidation and thermal stability characteristics improve machine cleanliness and reduce the needs for frequent maintenance services. The dual purpose nature does not compromise either hydraulic system performance or the stick-slip or chatter of ways allowing their effective use in both systems while reducing the potential negative effects of cross contamination of lubricants and water or water-based coolants.

Features Advantages and Potential Benefits
Low Frictional Characteristics Eliminates stick-slip and chatter of ways
Improves precision of parts
Provides consistent good work piece finish
Oxidation and Thermal Stability Allows extension of service intervals
Reduces deposit and sludge formation
Keeps equipment lubricated surfaces clean
Rust and Corrosion Protection Maintains excellent finish on ways
Reduces maintenance for rust and corrosion removal
Water and Water-Based Separability Reduces the negative effects of these materials on working surfaces
Enhances aqueous coolant batch life and performance
Facilitates removal of water and water-based coolants from hydraulic systems and enhances service life
Adhesive Properties Resists wash-off from ways
Protects surfaces from rust and corrosion
Assures consistent parts finish and accuracy
Load-Carrying Properties Reduce wear
Extend equipment life
Multi-metal Compatibility Provides protection of ferrous and non-ferrous components
Dual Purpose Design Eliminates concerns of cross contamination and product mis-application
Reduces need of extra product


  • Machine tools with a common system for hydraulics and way lubrication
  • Applications where cross-contamination of way lube with hydraulic oil can result in poor performance
  • Machinery with separate systems for ways and hydraulics where one oil is desirable for both systems
  • Areas where conventional mineral based lubricants are not adequately protecting way surfaces


Mobil Vacuoline 1400 Series has the following builder approvals: Mobil Vacuoline 1405 Mobil Vacuoline 1409 Mobil Vacuoline 1419
