Description:

Mobil Gas Engine Oil 15W-40 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 Gas Engine Oil 15W-40 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 Gas Engine Oil 15W-40 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 Gas Engine Oil 15W-40 is formulated 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

Application:

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 busses
