Mobil DTE 10 Excel 46 | Zinc-Free ISO VG 46 Hydraulic Oil South Africa
Mobil DTE 10 Excel 46 | Zinc-Free ISO VG 46 Hydraulic Oil South Africa
Mobil™ DTE 10 Excel Series — Zinc-Free Synthetic Hydraulic Oil
Mobil DTE 10 Excel 46
Zinc-Free, Ashless Anti-Wear Hydraulic Oil | ISO VG 46 | Very High Viscosity Index 150+
Zinc-Free — Ashless Additive System
Mobil DTE 10 Excel 46 is the most widely specified grade in the DTE 10 Excel Series — a fully ashless, zinc-free ISO VG 46 hydraulic oil delivering up to 6% improved pump efficiency versus conventional zinc-based hydraulic oils, alongside outstanding deposit control in servo and proportional valve systems.
ISO VG 46 is the standard hydraulic viscosity grade across the widest range of industrial and mobile equipment — general industrial hydraulic power units, mobile construction and mining machinery, and high-performance hydraulic systems requiring energy efficiency and precision control. The zinc-free ashless formulation eliminates the risks of zinc-induced corrosion and servo valve deposit build-up, while the VI 150+ maintains stable viscosity from cold start through full operating temperature — substantially outperforming the 104 VI typical of conventional zinc-based ISO VG 46 hydraulic oils.
Product Overview
Mobil DTE 10 Excel 46 is a premium zinc-free, ashless anti-wear hydraulic oil engineered for high-performance industrial and mobile hydraulic systems requiring the widely specified ISO VG 46 viscosity grade. It combines a very high viscosity index (VI 150+) with an advanced ashless additive system — delivering proven energy efficiency gains, outstanding system cleanliness, exceptional keep-clean performance in tight-tolerance servo and proportional valves, and full compatibility with sensitive hydraulic system components.
Independent and field testing has demonstrated up to 6% improved hydraulic pump efficiency versus conventional hydraulic oils at the same ISO VG 46 grade — translating directly into reduced power consumption and lower operating costs in continuous-use hydraulic systems across mining, manufacturing, marine and offshore operations.
Approved by Bosch Rexroth RE 90220, Parker Denison HF-0/HF-1/HF-2 and Eaton Vickers 694 — all achieved with the zinc-free formulation. Carries Fives Cincinnati P-70 approval for precision manufacturing. Meets DIN 51524-3 HVLP and ISO 11158 L-HV. Always confirm the correct grade from your OEM documentation before ordering.
Performance Benefits
Up to 6% Energy Efficiency Gain
Proven to improve hydraulic pump efficiency, reducing power consumption and lowering operating costs in continuous-use hydraulic systems — a meaningful saving across large equipment fleets in mining and industrial operations.
Advanced Keep-Clean Performance
Prevents deposit formation in tight-tolerance servo and proportional valves — extending filter life and ensuring system precision in high-performance hydraulic circuits where valve cleanliness determines control accuracy.
Very High Viscosity Index — 150+
VI 150+ vs 104 for conventional zinc-based ISO VG 46 hydraulic oil — maintains stable viscosity from cold overnight start through peak operating temperature, ensuring reliable performance across South African mining and industrial environments.
Zinc-Free Pump & Valve Compatibility
Ashless formulation fully compatible with silver-plated and yellow metal components in Bosch Rexroth and Denison pump systems — eliminating zinc-induced corrosion risk regardless of operating temperature or load condition.
Excellent Cold-Start Performance
Pour point of -42°C ensures reliable hydraulic system startup at low ambient temperatures — important for mobile equipment operating overnight in remote Northern Cape mining locations and outdoor industrial installations.
Extended Drain Intervals
Outstanding oxidation and thermal stability extends service intervals compared to conventional ISO VG 46 hydraulic oils — reducing oil change frequency, maintenance labour and fluid disposal costs across mining, marine and offshore equipment fleets.
