Zincfree Hydraulic Oil Boosts Industrial Equipment Efficiency

January 19, 2026

In modern industrial environments where higher productivity and extended equipment lifespan are paramount, hydraulic system reliability becomes critical. The Mobil DTE™ Zinc-Free Hydraulic Oil series represents a premium solution engineered to meet these demanding requirements.

Product Features and Advantages

This advanced hydraulic oil formulation combines high-quality base oils with specially selected zinc-free additives to deliver exceptional protection for high-pressure industrial and mobile equipment hydraulic systems. The series offers multiple performance advantages:

  • Superior wear protection: The unique additive system provides excellent anti-wear performance even in demanding hydraulic applications, extending equipment service life.
  • Exceptional oxidation and thermal stability: Helps prolong oil and filter service life while maintaining system cleanliness, reducing maintenance and waste disposal costs.
  • Outstanding water separation: Maintains effective operation when systems experience minor water contamination while quickly separating larger water volumes to protect system components.
  • Multi-metal compatibility: Ensures reliable performance and protection when used with pumps and system components containing various metal materials.
  • Broad equipment applicability: Meets requirements for diverse equipment types, helping reduce inventory needs.

The technical benefits translate into practical operational advantages:

  • Extended oil and equipment service life through superior thermal-oxidative stability that reduces oil degradation and extends drain intervals
  • Reduced wear on pumps and components through exceptional anti-wear performance, lowering failure rates
  • Protection for moisture-exposed systems through excellent water separation characteristics that ensure stable operation in humid environments
Application Areas

The Mobil DTE™ Zinc-Free Hydraulic Oil series suits numerous industrial applications including:

  • Pumps and system components with multi-metal designs
  • Applications where hydraulic oil and coolant may cross-contaminate
  • High-pressure vane, piston, and gear pumps
  • Systems where minor water contamination is unavoidable
  • Systems incorporating gears and bearings
  • Applications requiring high load-carrying capacity and wear protection
