Slow-speed, two stroke crosshead engines
Taro® Ultra 40

Taro® Ultra is new range of cylinder lubricants specifically designed to cope with the demands and required flexibility for IMO 2020. Taro Ultra cylinder lubricants have been fully field tested using a wide variety of fuels expected to be available post IMO 2020 implementation and are approved by major OEMs. Taro Ultra 40 is a 40 Base Number (BN) cylinder lubricant designed for lubricating the latest generation two-stroke marine engines running on low sulphur fuels under all loads and operating conditions. Taro Ultra 40 is blended with highly refined base oils and carefully selected additives to provide excellent ring and liner wear protection and piston cleanliness in slowspeed crosshead diesel engines.

Recommended Uses

Taro Ultra 40 is recommended for lubricating the cylinders of large low-speed marine diesel engines using:
* Continuous operation on Very Low Sulphur Fuel (VLSFO) and Ultra Low Sulphur Fuel (ULSFO), under all loads and operating conditions. Running on low sulphur fuel requires the reduction of BN introduced into the cylinder. This can be achieved by optimizing the oil federate. Taro Ultra 40 should be used in accordance with OEM guidelines and recommendations.
* ACOM (automated cylinder oil mixing) system that mixes Taro Ultra 40 and Taro Ultra 140 to the BN requested depending on sulphur content of the bunkered fuel.

Taro® Ultra 40 Is Approved For:

MAN Energy Solutions

WinGD (formerly Wärtsilä)

Japan Engine Corporation (formerly Mitsubishi/Kobe Diesel)

ACOM (automated cylinder oil mixing) according to MAN approval

Performance Benefits

1. Engine Protection

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

2. Engine Cleanliness

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

3. Storage Stability

Stable at ambient temperatures and during long-term storage.

4. Compatibility

Miscible and compatible with diesel cylinder lubricants generally known to the international marine trade.
