Advantages of Jenbacher N Oil 40


Extend your oil life by up to 100% while reducing lifecycle costs by as much as 30%. Available for INNIO Group's Type 2, 3, 4, 6 and 9 engines, Jenbacher N Oil 40 improves dry lubrication properties for enhanced valve protection and enhances dispercency for cleanliness and soot handling. Our advanced solvency provides high-temperature deposit control, too. 

Specifically developed and carefully validated new used oil limits for Jenbacher N Oil 40 provide extended but still reliable oil drain intervals. 

Actual results may vary. 


Co-developed by INNIO Group and ExxonMobil since 2015, Jenbacher N Oil 40 has accumulated more than 8 million hours of field validation with more than 800 units of long-term monitoring across multiple engine platforms. Our extensive field testing even proves the capability of sustaining performance within a high-severity gas engine fitted with thermally loaded steel pistons.


INNIO Group’s myPlant Asset Performance Management solution can be used to monitor oil quality, oil consumption, exhaust gas temperature, oil change intervals and more. Analytics help predict oil lifetime and ensure your gas engines’ performance and protection. Additional specialized technical support is available through Mobil ServSM.

With online monitoring, you get longer drain intervals, extended condemning limits, an optimized base oil and additive package, and enhanced dry lubrication properties—all without compromising protection of critical engine parts and components.
