Shell Lubricants is introducing into the market, a new member to the Mysella range of Gas Engine Lubricants. The new product, named Shell Mysella S5-S, has been especially formulated for gas engines running on all types of biogas, including gas produced from biomass or manure, sewage gas and landfill gas. In this webcast Shell will present findings of the research that has been executed during its development. The paper describes the challenges that different qualities of biogas impose on the engine and the lubricating oil. It describes what properties a lubricating oil for biogas operation should ideally have, and different formulation routes to achieve these. The performance of different candidate formulations is presented in the form of field trial results, where the focus is on:
- Extension of oil life, by looking at the candidate’s resistance to oxidation and its ability to neutralize acids from the combustion gas.
- Improved engine protection, by minimizing deposit formation tendency and maximizing engine cleanliness.
