Taro Special HT LS 400

SAE 50 Slow Speed Engine Oil

Taro® Special HT LS is a 40 BN SAE 50 cylinder lubricant particularly intended for lubricating the cylinders of the latest generation engines using low sulfur fuel (< 1.5 to 2 wt%) and operating at very high mechanical and thermal loads reaching up to 160 bar in maximum cylinder pressure and up to 270°C in liner temperature at top dead centre. Blended from highly refined, paraffinic base oils and carefully selected additives to provide good ring and liner wear protection and good piston cleanliness in low-speed crosshead engines. Taro® Special HT LS 40 has been developed specifically for high-pressure and high-temperature applications.

Pack Sizes: 205L  

Caltex Product Code: 3003

Applications

  • Cylinder lubrication of all crosshead-type marine diesel engines continuously using low sulfur fuel and operating at high specific power outputs and high thermal loads.

  • Running on low sulfur fuel requires the reduction of base introduced into the cylinder. This can be achieved by optimising the oil feed rate or selecting a diesel cylinder lubricant with a lower base number.

Performance Standards

Taro® Special HT LS 40 has been approved by MAN B&W and Wärtsilä for use in the latest generation engine designs.
