Advanced Fully Synthetic High Speed Marine Diesel Engine Oil

Product Description

Mobilgard 1 HSD is an Advanced Fully Synthetic High Speed Marine Diesel Engine Oil, that helps extend engine life while providing long drain capability1 and potential fuel economy² for modern and latest diesel engine technology operating in severe applications.


Mobilgard 1 HSD is a CK-4 API oil recommended for use in a wide range of operating environments found in the marine industry and heavy-duty applications.


The outstanding performance of Mobilgard 1 HSD is the result of extensive cooperative development work of ExxonMobil with major equipment builders and application of the latest lubrication technology.


As a result, this product meets or exceeds the requirements of the latest API and ACEA industry specifications for diesel engine oils, as well as the requirements of many engine manufacturers, including Cummins and Caterpillar.


1 Please refer to the owners' handbook for OEM application requirements and oil drain intervals for your vehicle or equipment.

2 Compared to an SAE 15W-40 engine oil. Actual savings are dependent on vehicle engine type, outside temperature, driving conditions, and your current engine oil viscosity.


Features and Benefits

Mobilgard 1 HSD is an outstanding lubricant solution for modern and latest engine technology equipped with emission after-treatment.


It was developed by ExxonMobil to maintain unsurpassed oxidation stability 3 while also delivering exceptional low temperature fluidity and pumpability for smooth starting in cold conditions. This feature, in combination with the sophisticated additive system, ensures exceptional engine wear performance and supports long engine life.


The low ash formulation protects at the same time all exhaust after-treatment devices incl. turbo charger and EGR to ensure proper long effective operation lifetime to protect the environment and meet the emission regulations.


The advanced engine cleanliness performance prevents deposits and protects the engine for long and efficient engine life.


3 Based on PC-11 industry test data.
