1. CHEVRON

* Taro Special HT 70

  Taro Special HT 70 is a high-performance 70 BN SAE 50 cylinder lubricant intended for lubricating slow-speed engines at very high mechanical and thermal loads. It is blended from highly refined, paraffinic base oils and carefully ed additives to provide superior ring and liner wear protection and excellent piston cleanliness in slow-speed crosshead engines. Taro Special HT 70 has been developed specifically for high- pressure and high-temperature applications.

PERFORMANCE BENEFITS

- Wear protection

Ensures protection against excessive cylinder liner and piston ring wear, thus allowing prolonged service intervals.

- Detergent/Dispersant properties

Prevents ring sticking and minimizes deposit formation throughout the combustion chamber exhaust areas.

- Excellent lubrication properties

Maintains an oil film under severe, high load conditions, thereby reducing frictional wear and preventing scuffing in lines, pistons and rings.

- Storage stability

Completely stable at all ambient temperatures. Will not separate or deteriorate in long-term storage.

- Compatibility

Fully miscible and compatible with single-phase alkaline diesel cylinder lubricants generally known to the international marine trade.

- Recommended uses

Taro Special HT 70 is recommended for lubricating the cylinders of all large slow-speed marine diesel engines operating at high specific power outputs and high thermal loads. Taro Special HT 70 has been approved by MAN, Wästsilä and Mitsubishi Heavy Industries for use in the latest

2. SHELL

* Shell Alexia Oil S4

  Shell Alexia Oil S4 is a premium grade cylinder lubricant for use in all types of low speed crosshead diesel engines burning residual fuels with sulphur contents of up to 3.5% weight. It is ideally suited for the new generation of highly rated, fuel efficient, slow-speed marine diesel engines operating with higher pressures, higher temperatures and longer strokes. It is a blend of highly refined, high viscosity index base oils, and additives that incorporate unique alkyl salicylate technology developed by Shell Research.

- Applications

• Low speed marine diesel engines burning heavy fuel with a relatively high sulphur content of between 1.0 to 3.5% weight

• Slow speed marine diesel engine cylinders

- Performance Features

• Unique alkyl salicylate additive technology

Imparts outstanding acid neutralising properties to counter corrosive wear resulting from the use of high sulphur fuels

• Minimum deposit formation

On cylinder ports, pistons, piston rings, ring grooves and under piston spaces

• Low cylinder and piston ring wear

Cylinder wear rates below 0.05 mm per 1000 hours are commonly experienced

• Excellent engine cleanliness

Extended interval between maintenance schedules - Periods between piston overhauls of up to two years are not unusual

• Storage stability

Completely stable in storage under all the widely varying conditions encountered aboard ship

• Sight-glass fluid compatibility

Compatible with all normal lubricator sight glass fluids

• Service experience

Developed over 35 years in close cooperation with ship-owners

- Performance Benefits

All manufacturers of slow-speed crosshead diesel engines approve the use of Shell Alexia Oil S4.

- Oil Feed Rates

Insufficient cylinder oil feed rates can lead to corrosive wear, seized and broken rings and consequent blow-by and scavenge fire risks, and to the formation of excessive and tenacious deposits, to obtain optimum performance with.

Shell Alexia Oil S4 it is important to:

• Observe the engine manufacturers recommended cylinder oil feed rates as the minimum

• Consider using higher rates, especially when running in new liners and /or rings

• Equally distribute the oil between injection quills

• Ensure the lubricator drive system is well maintained and properly adjusted

• Clean and overhaul lubricator boxes according to engine manufacturers recommendations

- Seal Compatibility

Shell Alexia Oil S4 is compatible with all normal oil seal materials

- Health & Safety

Shell Alexia Oil S4 is unlikely to present any significant health or safety hazard when properly used in the recommended application, and good standards of industrial and personal hygiene are maintained. Avoid contact with skin. Use impervious gloves with used oil. After skin contact, wash immediately with soap and water. For further guidance on Product Health & Safety refer to the appropriate Shell Product Safety Data Sheet.

- Protect the environment

Take used oil to an authorised collection point. Do not discharge into drains, soil or water.  generation engine designs.

3. MOBIL

* Mobilgard 570

- Product Description

Mobilgard™ 570 by ExxonMobil is a premium quality, extra high performance, marine diesel engine cylinder oil. The outstanding performance of Mobilgard 570 has been demonstrated at the elevated peak firing pressures and liner temperatures found in modern marine two stroke engines. It has an optimum viscosity of over 20 cSt. at 100ºC and low volatility to ensure excellent lubricant distribution and oil film retention. Through the use of unique synthetic thickener technology and a balanced formulation, the high viscosity and low volatility is attained with little or no use of bright stock which can create deposit formation due to poor thermal stability. Mobilgard 570 has demonstrated outstanding ring and liner protection and cleanliness under sustained operation with fuel sulphur levels down to 1.5%.

- Features and Benefits

Excellent thermal and oxidation stability can lead to reduced deposits and sludge formation. Cleaner engines can lead to reduced component wear rates.

Exceptional anti-wear properties lead to potentially reduced liner and ring wear and excellent anti-scuffing control.
Outstanding detergency capability leads to potentially cleaner pistons and liners and can help extend periods between overhauls.

- Applications

Marine crosshead engines
