Chevron’s new 100BN cylinder oil Taro Special HT 100 offers ship owners the ability to achieve the latest emissions legislation and has now received interim approval for its use in another key engine range – products made by Winterthur Gas & Diesel Ltd (formerly Wärtsilä).

A Wärtsilä engine has satisfactorily completed 2,000 hours of a 4,000-hour shipboard testing programme conducted by Chevron and reviewed by the company. After examining the results for the Wärtsilä 8RT-flex82T engine and analysis of samples of the lubricating oil, Winterthur Gas & Diesel Ltd has now issued an Interim No Objection Letter (NOL) covering the use of the lubricant. Chevron expects that a full NOL will be issued assuming the satisfactory completion of the remaining portion of the test cycle.

The interim approval allows the use of Taro Special HT 100 oil in Wärtsilä RTA, RT-flex and W-X engines as well as in Sulzer 2-stroke engines operating on fuels with sulphur contents in the range of 2.0 to 3.5% on a continuous basis.
