Chevron Marine Lubricants receives first OEM approval for latest
high BN cylinder oil Taro® Special HT Ultra

Chevron Marine Lubricants has been working closely with key customers and
MAN Diesel & Turbo to develop Taro® Special HT Ultra.

A new 2-stroke cylinder lubricant able to cope with the demands of the latest high efficiency engines on the market today whilst running on high sulphur fuel at low speeds.

Taro® Special HT Ultra provides the flexibility required for blending on board (BOB) and is the first 140BN cylinder lubricant OEM approved for use on its own for ultra-high corrosion environments, following extensive laboratory and on-board trials.

These new engines have an increased tendency to develop cold corrosion inside the cylinder than the older, less efficient units. To mitigate the effects of this highly corrosive environment, several methods are possible with the easiest to simply increase cylinder lubricant feed rates. However this is not always the most economical strategy and would be more efficient to switch to a higher BN lubricant once a certain rate is reached. This will provide the same level of corrosion protection with less product injected into the cylinder.

Naturally, injecting more alkalinity than necessary is not economical and may in fact cause performance issues. Ship operators should therefore make sure to use the right oil to get maximum engine protection at the lowest cylinder lubricant federate. Using Chevron Marine Lubricants DOT.FAST® on board drip oil monitoring in conjunction with FAST™ on-shore testing provides data to enable the vessel to optimise the feed rate on-board to balance wear against consumption ensuring the lowest possible running costs.

Chevron Marine Lubricants continue to offer the full range from low BN products such as our 25BN Taro® Special HT LF to our latest high, 140BN product Taro® Special HT Ultra ensuring all of our customers needs across a wide range of operating conditions are met while continuing to provide optimal engine protection and cost management.
