Product Description

Mobil Delvac™ Legend 15W-40 CNG/LNG is a premium fleet engine oil specifically formulated to provide reliable protection for trucks and buses using Compressed Natural Gas (CNG) or Liquefied Natural Gas (LNG). Mobil Delvac™ Legend 15W-40 CNG/LNG is formulated from high quality base stocks and a balanced additive system. This advanced medium ash formulation provides excellent oxidation, nitration, and thermal stability to minimize combustion chamber ash deposits. Mobil Delvac™ Legend 15W-40 CNG/LNG lubricates with less varnish, sludge, and carbon build-up under the most severe operating conditions.


Features and Benefits

Modern high output, high speed, lean-burn diesel type engines using natural gas fuels place severe demands on engine lubricants. Mobil Delvac™ Legend 15W-40 CNG/LNG is formulated according to strict standards to deliver reliable engine performance in modern diesel type engines using natural gas as the primary fuel. The key benefits include:


•  High thermal and oxidation stability helps control sludge build-up and deposits.

•  Reserve TBN neutralizes oxy acids and nitrates to reduce deposits.

•  Shear stability reduces oil consumption and provides bearing wear and cylinder liner scuff protection.

•  Effective detergency/dispersancy keeps engines cleaner.

•  Low levels of Zinc and Phosphorous help extend catalytic converter life.



Recommended by ExxonMobil for use in:


•  Spark ignited CNG and LNG-fueled lean-burn engines.

•  Dual fuel engines using diesel fuel for start-up and 15% diesel pilot fuel with CNG/LNG.

•  On-highway light and heavy-duty trucks and buses.
