Taro® Ultra 20
Taro Ultra 20 is approved by Winterthur Gas & Diesel (Wärtsilä) for latest generation engines, including WinGD dual fuel engines operating with gas fuels.
Taro® Ultra 20 is a 20 Base Number (BN) cylinder lubricant designed for lubricating the latest generation two-stroke marine engines operating at high mechanical and thermal loads under all operating conditions on low sulphur fuels (<0.1% sulphur), including those in continuous operation within Emissions Control Area (ECA) zones and LNG operation.
Taro Ultra 20 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.

Taro Ultra 20 is recommended for lubricating the cylinders of large low-speed marine diesel engines continuously using low sulphur fuel (<0.1% sulphur), under all loads and operating conditions, including those in continuous operation within Emissions Control Area (ECA) zones.
Running on low sulphur fuel (<0.1% sulphur) requires the reduction of base introduced into the cylinder.
Taro Ultra 20 is approved by Winterthur Gas & Diesel (Wärtsilä) for use in the latest generation engine designs, including WinGD dual fuel engines operating with gas fuels.
Taro Ultra 20 has an interim No Objection Letter (NOL) from MAN ES.
Taro Ultra 20 should be used in accordance with OEM guidelines and recommendations.
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
3. Storage Stability
Stable at ambient temperatures and during long-term
Miscible and compatible with diesel cylinder lubricants
generally known to the international marine trade.
