Mobil EAL 224H provides excellent anti-wear, lubricity, and film strength performance in hydraulic and circulation systems operating under moderate operating conditions. The ready biodegradability and virtually non-toxic nature of this product makes it an excellent choice where leakage or spillage could enter environmentally sensitive areas. The inadvertent leakage of spillage of this product in environmentally sensitive areas could result in easier clean-up and lower remediation costs.

Features Advantages and Potential Benefits
Ready Biodegradability and Non-Toxicity Reduces potential for environmental damage
Lowers potential remediation and clean-up costs caused by spills or leakage
Becomes an integral part of plant environmental program
Outstanding Load-Carrying and Anti-Wear Properties Protects system components against wear and scuffing
Provides long equipment life
Exceptional Corrosion Protection Reduces corrosion of internal system components
Excellent Multi-Metal Compatibility Will not react with steel or copper alloys
Good Elastomer Compatibility Works well with same elastomers used with conventional mineral based oils. No need for special seals or elastomers


  • Hydraulic systems where spills or leakage could result in damage to the environment
  • In systems where readily biodegradable and virtually non-toxic fluids may be required
  • Gear systems requiring either an ISO VG 32 or 46 oil with mild extreme-pressure characteristics
  • Systems containing servo-valves
  • Hydraulic systems operating with oil temperatures in the range of 0 F to 180 F
  • Marine and mobile equipment operating in environmentally sensitive areas
  • Circulation systems operating under mild to moderate service conditions
  • Industrial hydraulic systems where leaked or spilled fluids could get into plant effluent
  • Air line oilers and some limited oil-mist generating systems
  • Air-over-hydraulic fluid systems operating in environmentally sensitive areas


Mobil EAL 224H recommended for use in applications requiring:
Environmentally friendly characteristics
