Product Description

Mobil EAL Envirosyn H Series oils are super premium, high performance fully synthetic environmentally aware hydraulic and circulating oils designed to provide outstanding performance in systems operating at moderate to severe conditions. They provide excellent wide temperature range performance above and beyond the capabilities of non-synthetic environmentally aware oils. Mobil EAL Envirosyn H Series provides exceptional anti-wear and film strength characteristics necessary for hydraulic systems operating under high load and high pressures. This is verified by their excellent wear control in the ASTM D 2882 and Vickers 35VQ25 Pump Wear Tests. Their 12-stage rating in the FZG Gear Load Test demonstrates a high level of protection against wear and scuffing and the suitability of this product to protect gears and bearings used in conjunction with hydraulic systems. The Mobil EAL Envirosyn H Seriess provide excellent protection against corrosion and ensures very good multi-metal compatibility allowing its use in systems employing various metallurgy that may be used in pump and component design. They also provide very good thin oil film protection against rusting. In addition to their exceptional performance capability, they satisfy the requirements for ready biodegradability and non-toxicity making them a desirable product for severe operating conditions where leakage or spillage of conventional oils could result in damage to the environment.


Mobil EAL Envirosyn H Series oils are formulated from select, high-quality, high-VI synthetic base oil materials and high technology additive system specifically engineered to meet or exceed the performance requirements of most hydraulic pump and system builders while satisfying the stringent criteria for biodegradability and toxicity. Compared to the best vegetable oil-based and synthetic ester based hydraulic oils, these products provide improved oxidation stability and anti-foam performance, together with improved high and low temperature performance (-20º F to 200º F).


Features and Benefits

Mobil EAL Envirosyn H Series oils provide excellent wide temperature range performance. Their exceptional anti-wear, lubricity, and film strength characteristics assure performance in hydraulic and circulation systems operating under moderate to severe conditions. The ready biodegradability and virtually non-toxic nature of these products make them 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.
