Description:

Taro Special HT LS 40 is a high-performance 40 BN SAE 50 cylinder lubricant particularly intended for lubricating the cylinders of the latest generation slow-speed engines using low sulphur fuel (<1.5 to 2 wt% sulphur) and operating at very high mechanical and thermal loads reaching up to 160 bar in maximum cylinder pressure and up to 270 degrees Celsius in liner temperature at top dead center.

Taro Special HT LS 40 is blended from highly refi ned, paraffi nic base oils and carefully selected additives to provide superior ring and liner wear protection and excellent piston cleanliness in slow-speed crosshead engines. Taro Special HT LS 40 has been developed specifi cally for high-pressure and high-temperature applications.

Recommended Uses:

Taro Special HT LS 40 is recommended for the cylinder lubrication of all slow-speed marine diesel engines continuously using low sulphur fuel and operating at high specifi c power outputs and high thermal loads. Running on low sulphur fuel requires the reduction of base introduced into the cylinder. This can be achieved by optimizing the oil feed rate or selecting a diesel cylinder lubricant with a lower base number. Taro Special HT LS 40 has been approved by MAN Diesel and Wärtsilä.

Performance Benefits:

1. Wear Protection
Protects against excessive cylinder liner and piston ring wear, thus allowing prolonged service intervals.

2. Detergent/Dispersant Properties
Prevents ring sticking and minimizes deposit formation throughout the combustion chamber areas.

3. Excellent Lubrication Properties
Maintains an oil fi lm under severe, high load conditions, thereby reducing frictional wear and preventing scuffi ng of liners, pistons and rings.

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

5. Compatibility
Fully miscible and compatible with alkaline cylinder lubricants generally known to the international marine trade.
