Mobil Velocite Oil No. 8
ISO VG 15 Spindle Oil for Precision Machine Tool Lubrication
Mobil Velocite Oil No. 8 is an ISO VG 15 spindle oil designed for high-speed machine tool bearings and precision equipment where fine clearances and reliable oil flow are important. Also searched as Mobil Velocite No. 8 or Mobil Velocite Oil Number 8, this low-viscosity spindle oil is part of the Mobil Velocite Oil Numbered Series.
Mobil Velocite No. 8 provides a viscosity position between the lighter Mobil Velocite No. 6 and the heavier Mobil Velocite No. 10. This ISO VG 15 spindle oil is useful where that viscosity is specified for spindle bearings, sleeve-type bearings, or related machine tool applications.
Its formulation helps support lubrication in close-tolerance components while offering oxidation resistance, rust and corrosion protection, water separation, and foam control. For buyers maintaining machine tools or precision equipment, Velocite Oil No. 8 is a practical option when the equipment calls for ISO VG 15 spindle oil, precision spindle oil, or light machine oil.
