3. Performance Features & Benefits
- Very high viscosity index (VI ≥ 160) — stable across wide temperature range
- Superior energy efficiency vs. mineral oil (up to 3% reduction)
- Extended drain intervals — up to 3× mineral oil service life
- Excellent low-temperature fluidity
- Not compatible with mineral oil or ester-based lubricants — flush required
4. Applications
- High-efficiency worm gear drives
- Gearboxes requiring extended drain intervals
- High-temperature applications (up to 120°C continuous)
- Energy-critical drives where friction reduction is priority
- Food-adjacent applications (non-food-grade; consult NSF H1 range)
