Jenbacher N Oil 40

High Performance Gas Engine Oil for Natural Gas Applications

Jenbacher N Oil 40

Jenbacher N Oil 40 is a high performance gas engine oil formulated for current & next generation of Jenbacher natural gas engines. It has been designed as a major component of the engine, in close cooperation between INNIO Jenbacher1 and ExxonMobil4 engineers.

With more than 8 million hours of accumulated field data from long term monitoring in more than 800 units, the formulation of Jenbacher N Oil 40 engine oil has been confirmed to provide 2 times2 extended oil life and reduced life cycle costs (LCC) of up to 30% compared to other typical approved gas engine oils3. Specifically developed and carefully validated new used oil limits have been released by INNIO Jenbacher for this product to provide extended and reliable oil drain intervals.

Jenbacher N Oil 40 can help users keep their Jenbacher engines running longer and cleaner2 with improved reliability, excellent alkalinity reserve and retention, resulting in increased productivity.



Jenbacher N Oil 40 is approved for the whole range of Jenbacher natural gas engines – Type 2, Type 3, Type 4, Type 6 and Type 9.

For latest approvals, refer to INNIO Jenbacher's technical instructions TA 1000-1109 and TA 1000-1108 which can also be found at (internet) or (intranet for signed-in users only).
