ISO VG 150 grade oils
Viscosity is the first thing to settle when choosing an oil: load-carrying capacity, film thickness and cold-start behaviour all follow from it. This page covers the equipment that typically calls for ISO VG 150 and lists the catalogue products in that grade.
Where this grade is used
- Compressor & Refrigeration Oils
- Gear & Bearing Oils
- Specialities & Other Fluids
ISO VG 150 products in the catalogue
- Shell Corena S2 P 150 — Air compressor oil
- Shell Morlina S2 B 150 — Bearing & circulation oil
- Shell Omala S2 G 150 — Industrial gear oil
- Shell Omala S2 GX 150 — Industrial gear oil
- Shell Omala S4 Gxv 150 — Synthetic gear oil
- Shell Omala S4 WE 150 — Synthetic gear oil
- Shell Naturelle S4 Gear Fluid 150 — Environmentally acceptable lubricant
Before changing grade
- Moving one grade up increases film thickness but makes cold pumpability harder.
- Moving one grade down reduces churning losses yet raises the risk of film breakdown under high load.
- The equipment builder's viscosity window should be the reference for any change.
- If the system is not fully drained, the resulting mixed viscosity has to be accounted for.
