Applications
The Mobilgard 12 Series diesel engine oils are intended for use as cylinder and bearing lubricants in marine and
industrial diesel engines operating on distillate fuels or light fuel blends. They are particularly effective in high
speed engines in fishing fleets; in new, severe service engines; and in many types of medium speed engines.
They may be used as crankcase lubricants in large crosshead type diesel engines operating on high sulphur fuels.
