Slow-speed, two stroke crosshead engines
Taro® Ultra 140

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. Taro Ultra 140 is a 140 Base Number (BN) cylinder oil specially formulated for use in high corrosion environments. As an ultra-high base number cylinder lubricant, this product is created for the latest type of highly efficient two-stroke engines which have an increased tendency to develop cold corrosion inside the cylinder than the older, less efficient installations. Taro Ultra 140 provides the same level of alkalinity and corrosion protection as Taro Ultra 100 at lower feedrates, therefore helping to reduce operating costs. Taro Ultra 140 a is blended with highly refined base oils and carefully selected additives to provide excellent ring and liner wear protection and piston cleanliness in slow-speed crosshead diesel engines.

Recommended Uses

Taro Ultra 140 is recommended for lubricating the cylinders of the latest generation large low-speed marine diesel engines equipped with exhaust abatement technologies operating with heavy fuel oil, under all loads and very corrosive operating conditions. The base number of Taro Ultra 140 makes this product ideal for use in engine types and under operating conditions which are sensitive to cold corrosion in the cylinder. Taro Ultra 140 should be used in accordance with OEM guidelines and recommendations. Taro Ultra 140 can also be used in combination with Taro Ultra 25 in MAN Energy Solutions diesel engines equipped with Automated Cylinder Oil Mixing (ACOM).

Performance Benefits

1. Engine Protection

Effective acid neutralization ensures protection against excessive cylinder liner and piston ring wear resulting from the use of high sulphur heavy fuel oils, thus extending cylinder liner and piston ring life.

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.

5. Operating cost

Ultra-high base number formulation provides the same level of alkalinity and corrosion protection at lower feedrates, reducing operating cost.
