Shell Tellus S2 MA 46 (Tellus DO 46) 209L hydraulic oil hydraulic systems in industrial equipment, protection against wear, corrosion, friction and foam reduction, load transfer
Description
Shell Tellus S2 MA 46 is a detergent hydraulic oil (HLPD) designed for systems exposed to water and solid contaminants. The advanced ashless formulation delivers excellent antiwear protection and consistent system performance.
Benefits and unique features
- Effective dispersion of water and solids – cleaner systems and reduced corrosion risk
- Ashless AW package – high load carrying (FZG/Brugger) with low friction
- Very good anti-foam and rapid air release – accurate valve response
- High oxidation stability – extended drain intervals
- Excellent filterability – compatible with fine filtration
Properties and applications
- HLPD hydraulics: injection moulding machines, electronically controlled hydraulics, mobile hydraulics
- Machine shops: spindles and hydraulics in automatic lathes, especially where synthetic/semi-synthetic coolants are present
- Watery environments: corrosion protection and steady operation in the presence of moisture
- Operational behaviour: low tendency to stick-slip

Storage recommendations
Store tightly closed in a cool, well-ventilated place. Protect from extreme temperatures and sunlight. Use clean containers (soft steel/HDPE recommended); avoid PVC. Dispose of used oil in accordance with regulations.
FAQ
Where is HLPD preferred?
In systems exposed to water/coolants and dust—its detergent action keeps systems clean.
Mixing with other oils?
Compatible with most mineral oils; do not mix with different classes (e.g., biodegradable, fire-resistant).
Typical viscosities?
46 cSt (40 °C) and 7 cSt (100 °C), VI 107.
Very cold starts?
For extreme cold starts, consider a variant with enhanced low-temperature fluidity.
