Maximum Film Thickness

ISO VG 150 delivers the highest film thickness of any grade in the DTE 10 Excel Series — ensuring adequate oil film between hydraulic actuator and pump components under the most extreme load and temperature conditions encountered in South African heavy industrial operations.

Zinc-Free for Extreme Conditions

At the elevated operating temperatures typical of ISO VG 150 applications, zinc-based additives decompose most rapidly — accelerating deposit formation on valve surfaces and filter media. The ashless formulation maintains system cleanliness under the most extreme thermal conditions.

VI 150+ at Maximum Viscosity Grade

The combination of ISO VG 150 and VI 150+ delivers the most stable viscosity-temperature profile of any hydraulic oil in this weight class — maintaining adequate film at very high operating temperatures while still providing reasonable cold-start performance.

Outstanding Oxidation Stability

Exceptional thermal and oxidation stability at the very high sump temperatures typical of ISO VG 150 applications — extending drain intervals and reducing maintenance costs in large high-temperature industrial hydraulic systems.

High Flash Point — 238°C

High flash point provides maximum safety margin in very high-temperature applications — reducing hydraulic fluid fire risk from high-pressure leaks near hot process equipment and furnace areas in heavy industrial environments.

Full OEM Compatibility

Bosch Rexroth, Denison and Eaton approved at ISO VG 150 — ensuring compatibility with the hydraulic pump and valve components specified by OEMs of heavy industrial machinery requiring maximum viscosity grade hydraulic fluid.
