Manufacturer's description

Mobilgard 312 is an SAE 30 high-performance diesel engine oil from the Mobilgard 12 Series, developed for trunk piston engines operating on low-sulphur distillate fuels in marine and industrial applications. It is formulated for excellent resistance to oxidation and viscosity increase over long service periods, with superior water-separating properties and excellent corrosion protection. The oil serves as a cylinder and bearing lubricant in marine and industrial diesel engines running on distillate fuels or light fuel blends, and is particularly effective in high-speed engines in fishing fleets, new severe-service engines and many medium-speed engines; it may also be used as a crankcase lubricant in large crosshead diesel engines running on high-sulphur fuels. Benefits include excellent thermal and oxidation stability that extends periods between inspections and overhauls, improved anti-wear properties that reduce ring and liner wear, and excellent TBN reserve and detergency/dispersancy for cleaner, longer-lasting engines. Mobilgard 312 is of API CF quality level. Typical properties include a viscosity of 12 mm²/s at 100°C and 108 mm²/s at 40°C, a viscosity index of 100, TBN of 15 mgKOH/g, sulfated ash of 2.1 wt% and a pour point of -9°C.

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.

Performance & benefits

• Mobilgard 12 Series is formulated with base oils having proven successful performance in diesel engines.
• The additive system is balanced to provide excellent resistance to thermal degradation under moderately severe operating conditions.
• They also provide good engine cleanliness and superior wear protection.
• Excellent thermal and oxidation stability: extended periods between inspections, overhaul and cleaning.
• Improved anti-wear properties: reduced ring and liner wear.
• Excellent TBN reserve and retention: increased protection against corrosive wear.
• Excellent detergency/dispersancy properties: increased oil service life and cleaner engines.
