Mobilgard 1 SHC by ExxonMobil is a supreme performance, synthetic diesel engine oil specifically formulated to address the needs of high power, distillate fueled diesel engines. It provides unsurpassed lubrication including long drain capability ａnd extended engine life for today＇s marine diesel engines operating in severe applications.

The unsurpassed performance capabilities of Mobilgard 1 SHC are the result of extensive cooperative development work with major equipment builders combined with the latest engine lubrication engineering. It is especially effective in extreme temperature applications. A true SAE 40 grade lubricant, on very hot engine parts, it provides stronger lubrication film strength than most SAE 50 engine oils. At low temperatures, it flows like an SAE 20W product ａnd thus provides outstanding start-up reliability ａnd wear protection at extreme low temperatures as low as -54ºC.

Revolutionary load carrying additives also make Mobilgard 1 SHC an outstanding wide temperature range gear lubricant.

Modern high performance, low emission, diesel engines in severe-service applications significantly increase the demands on engine lubricants. Current engine designs are tighter, reducing oil consumption ａnd resulting in less fresh oil make-up to replenish depleted additives. Top piston rings may be located higher bringing the oil film closer to the combustion chamber where temperatures increase thermal stress on the lubricant. Higher fuel injector pressure ａnd retarded timing improve control of exhaust emissions, but also increase engine temperatures ａnd increase soot loads in engines operating with exhaust gas re-circulation. Mobilgard 1 SHC can provide satisfactory lubrication at temperatures significantly higher than the upper limit for other extra high performance diesel engine oils. Its inherent viscosity is SAE 40 ａnd on very hot engine components it resists oil film breakdown better than conventional SAE 50 lubricants. The synthetic chemistry ａnd wax free nature also provides low temperature pumpability in comparison with a conventional SAE 20W lubricant. Mobilgard 1SHC is fully compatible with conventional oils.

Mobilgard 1 SHC has all the advantages of an SAE 40 weight oil without the higher oil consumption inherent in multigrade oils that use very light base stocks to achieve low temperature performance. Because of the unique molecular structure of the advanced base stocks used, combined with a highly responsive additive system, Mobilgard 1 SHC is not as volatile in the high temperature ring-belt area of the pistons in turbocharged engines. It reduces oil consumption ａnd wear, while improving fuel economy.

Mobilgard 1 SHC is also environmentally friendly in that it can significantly extend oil drain intervals beyond conventional oils which reduces waste oil disposal. In addition, the formulation is designed without the use of zinc ａnd with low chlorine levels well below the most stringent regulations in effect today.

Key features ａnd potential benefits include:

Mobilgard 1 SHC is recommended for use as a crankcase lubricant in medium ａnd high speed diesel engines in severe marine service. It is especially suited to the needs of high power concentration engines where thermal stress ａnd loading on the lubricant are severe, as well as for applications involving low-temperature ａnd /or frequent start-up, rapid loading following rapid start-up, ａnd abrupt shutdown after high speed operations.

Specific applications include:

• Military patrol vessels, high speed ferry/passenger vessels, racing boats ａnd luxury yachts
• Life ａnd rescue boat engines, emergency generators, auxiliary engines
• Marine gearing applications where FZG Level 12 is required
• Fully compatible with conventional mineral oils ａnd mineral oil systems
• Can be used in confidence in engines containing silver bearing components due to non-zinc formulation
