1. CHEVRON

* Veritas 800 Marine SAE 30

- Product information

Alkaline, Low Speed Diesel Engine System Oil

Premium quality, alkaline diesel engine oil designed for crankcase (system) lubrication of large, low speed diesel engines in marine and stationary applications.

 - Benefits

Extends time between overhauls

Special detergent and ashless dispersant additive system ensures crankcases and lubricating oil lines are kept free of deposits. The combination of detergency and excellent oxidation stability provides clean piston cooling galleries and chambers.

Protects bearings from corrosive wear

Level of alkalinity reserve ensures that acidic combustion products (which enter the crankcase due to leaks in the connecting rod seals) are effectively neutralized to protect bearings and bright metals against corrosive wear.

Easy oil purification

Combination of highly refined basestocks and special detergent additive system provides excellent water tolerance and separation properties which enable efficient purifier operation. Therefore, water washing is neither necessary nor recommended.

- Application

Crankcase lubrication of:

• Large, low speed (less than 250 rpm), two-cycle crosshead diesel engines

• Particularly suitable for engines with oil-cooled pistons

• Older-type marine trunk piston engines with separate cylinder lubrication

• Marine and stationary applications

2. SHELL

*  Melina S30

- Product information

System Oil for Low-Speed Crosshead Diesel Engines

Shell Melina S Oil 30 is a premium system oil for low-speed crosshead diesel engine crankcase and piston cooling systems. It is an alkaline oil giving the highest levels of machinery protection, a multi-purpose marine lubricant proved by many years of outstanding service.

- Performance Specifications

Shell Melina S Oil 30 is fully approved by Sulzer Bros and B and W/MAN as a system oil for their crosshead marine diesel engines. It is also widely recommended for a large range of other items of shipboard machinery.

Shell Melina S Oil 30 exceeds a 10th stage pass in the German FZG gears test.

- Application

+ General marine applications
 

+ Low speed marine diesel engine
 

+ Marine crosshead engines
 

+ Marine diesel engines
 

+ Marine systems
 

+ Note

Shell Melina S Oil 30 is not designed for use in auxiliary engines or other four-stroke medium-speed trunk-piston type engines.

- Performance Benefits

Alkalinity to resist corrosive attack by leakage of strong acid from cylinders.

Rust inhibition to protect the engine against corrosion by salt or fresh water contamination.

Demulsibility to ensure removal of contaminating water by centrifugal treatment.
 

• Anti-oxidancy to combat thermal degradation. particularly in engines where the oil is used for piston cooling.
 

• Detergency to ensure clean piston undercrowns.
 

• Extreme pressure characteristics to ensure suitability in shipboard non- engine gear applications.
 

• Long-term storage stability.
 

• Compatibility with other lubricants.
 

• Resistance to micro-biological degradation.
 

• Air release/anti-foam properties. 
 

3. MOBILL

* Mobillgard 300

- Product Description

Mobilgard™ 300 by ExxonMobil is a premium quality, extra high performance system oil designed for crosshead diesel engines. High quality paraffinic base oils along with a balanced additive system provide excellent protection even for the severe operating conditions of the latest design, high-output crosshead marine diesel engines. This product has sufficient alkalinity to neutralise any strong acids which may find their way into the crankcase from the combustion of fuel sulphur, and it has enhanced load carrying ability in order to reduce wear in heavily loaded bearings.

- Features and Benefits

Mobilgard 300 is formulated from high quality paraffinic base oils that have excellent thermal stability and oxidation resistance. These base oil characteristics are augmented with a balanced additive system that includes special high temperature oxidation inhibitors, alkaline detergents, a load carrying component and defoamant. The formulation has maximum antiwear properties, good rust protection in the presence of salt water, and excellent water separation characteristics.

- Applications

Mobilgard 300 is recommended primarily for use as system oil in late model, high-output, crosshead diesel engines, especially those engines employing the system oil for piston cooling. It will prevent or reduce deposit formation in the piston cooling spaces, thus maintaining piston cooling efficiency and reducing the incidence of piston top burning and piston crown cracking. It will also prevent or reduce crankcase deposits and will provide outstanding protection for heavily loaded bearings. Its reserve alkalinity allows for the burning of high sulphur fuel. Good rust prevention and water separation characteristics make Mobilgard 300 an excellent system oil in older design crosshead diesel engines which have water-cooled pistons and where crankcase deposits can be a problem with lower-quality system oils.
