Total Lubmarine’s Talusia Universal (BN57) has received a “No Objection Letter“ (NOL) from ship engine maker Winterthur Gas and Diesel (WinGD) for all marine fuels (liquid and gas) with a sulphur content of between 0.00% and 1.50%.
Talusia Universal is a single marine cylinder oil solution, designed to lubricate engines using a wide range of marine fuels. Talusia Universal (BN57) is designed for two-stroke engines built before 2008 and is compatible with marine fuels with less than 1.50% sulphur, which includes the 0.5% sulphur fuels compliant with the International Maritime Organization (IMO) mandate which took effect on 1 January 2020.
“Our team worked extremely closely with WinGD, and this close cooperation was critical in achieving this successful outcome. Test results on both engines revealed high levels of cleanliness with negligible wear, demonstrating the effectiveness of Talusia Universal,” Total Lubmarine’s Technical Director, Jean-Philippe Roman, said.
The NOL was awarded with no restrictions following the successful completion of two rigorous tests carried out on two different vessels fitted with W6X72 engines.
The tests were conducted on split engines comparing Talusia Universal with a BN40 reference cylinder lube oil (CLO). One test carried out with compliant very low sulphur fuel oil (VLSFO) with less than 0.5%S, the other one with compliant ultra-low sulphur fuel oil (ULSFO) with less than 0.1%S for 2,350 and 2,000 running hours, respectively.
“Following both tests, Talusia Universal performed significantly better than the reference CLO for deposit control and general piston cleanliness, while maintaining excellent wear rates,” said Justin Van Tries, Total Lubmarine’s engineer responsible for sea trials.
Talusia Universal Base Number 57 (BN 57) has also been approved by major ship engine manufacturers MAN Energy Solutions, Wartsila and Mitsubishi Heavy Industries.
Talusia Universal is formulated with a unique chemistry (with additional surfactant molecules) that helps the neutralization process and the control of engine deposit growth.
It is proven to handle the engine cleanliness demands of all technologies operating with low sulphur fuels in all conditions with an accumulated experience of more than 12 years.
The efficiency of Talusia Universal to maintain the engine cleanliness is as good as the high base number-rated products in the market, according to Total Lubmarine. It can also be used on WinGD engines with X-DF technology.
The NOL from WinGD follows the awarding of an NOL from MAN Energy Solutions in late 2019 for Talusia Universal, following tests carried out on MAN B&W two-stroke engines operating on fuels with less than 0.5%S VLSFO.
Because of its approval tests Talusia Universal can be used continuously with 0.1%S 2020 compliant fuels, in both the WinGD DF and MAN GI engines running in gas mode, without the risk of deposit growth.
