Mobilgear SHC™ MT 68
Mobilgear SHC™ MT 68 synthetic extreme-pressure marine gear oil is formulated to optimise the performance of equipment operating under extreme operating conditions. The oil was designed especially for marine thruster and azimuth gear drives requiring an ISO 68 viscosity gear oil with extreme-pressure additive protection.
Mobilgear SHC MT 68 thruster gear oil is formulated to provide protection against conventional wear such as scuffing while also offering a high level of resistance against micropitting. It also offers outstanding resistance to rust and corrosion.
Mobilgear SHC MT 68 marine gear oil can help extend gear and bearing life, maximise oil life and drain intervals, and reduce overall maintenance operating costs.
Mobilgear SHC MT 68 oil is approved by thruster system manufacturer Brunvoll.

Features and Benefits
- Mobil brand lubricants designated as SHC are recognised and appreciated around the world for innovation and outstanding performance. These molecular design PAO synthetic products, pioneered by our research scientists, symbolize the continuing commitment to using advanced technology to provide outstanding products.
A key factor in the development of Mobilgear SHC MT 68 was the close contacts between our scientists and application specialists with key OEMs to ensure that our product offerings will provide exceptional performance with the rapidly evolving marine gear designs and operation. To address the issue of micropitting gear wear, our product formulation scientists designed a proprietary combination of additives which would resist traditional gear wear mechanisms as well as protecting against micropitting. Our formulators chose proprietary PAO synthetic base oils to provide exceptional oil life and deposit control and resistance to thermal/oxidative and chemical degradation, as well as the balance of the performance features. The wax-free nature of the synthetic base oil also provides low temperature fluidity characteristics unmatched by mineral products and is a key benefit for remote, low ambient, applications. Mobilgear SHC MT 68 lubricants offer the following benefits:
|Features||Advantages and Potential Benefits|
|Superb protection from micropitting fatigue wear as well as high resistance to traditional scuffing wear||Extended gear and bearing life in marine enclosed gear drives operating under extreme conditions of load, speed and temperature|
|Excellent resistance to degradation at high temperature||Extended oil life and drain intervals reduced oil consumption and manpower costs|
|Low traction PAO base stocks for improved gear efficiency||Reduced energy consumption and lower operating temperatures|
|High viscosity index base stocks reduce viscosity change with temperature||Ability to operate at both high and low temperatures: especially critical in marine applications|
|Excellent resistance to rust and corrosion and very good demulsibility||Smooth, trouble-free operation at high temperatures or in water-contaminated applications|
|No filter plugging, even in presence of water||Less filter changes and reduced maintenance costs|
|Excellent compatibility with common gearbox materials of construction and with mineral-based gear oils||Easy changeover from mineral products|
- Application Considerations: While the Mobilgear SHC MT 68 is compatible with mineral oil based products mixture may detract from their performance. Consequently it is recommended that before changing a system to Mobilgear SHC MT 68, it should be thoroughly cleaned out and flushed to achieve the maximum performance benefits.
- Mobilgear SHC MT 68 is a premium performance, fully synthetic marine gear oil designed to provide optimum equipment protection and oil life even under extreme conditions. They are especially formulated to resist micropitting of modern gearing and can operate in both high and low temperature environments.
- The product was designed especially for marine thruster/azimuth gear drives requiring an ISO 68 viscosity gear oil with Extreme Pressure (EP) additive protection. Mobilgear SHC MT 68 has approvals from major marine thruster OEMs such as Brunvoll.
