Features and Benefits

Many modern, low emission diesel engines generate more soot and operate at higher temperatures than older engines. This significantly increases the need for high performance lubricants. Current tighter engine designs reduce oil consumption, resulting in less fresh oil makeup to replenish depleted additives. Top piston rings are located higher, bringing the oil film closer to the combustion chamber and exposing the lubricant to severe thermal stresses. Mobil Delvac 1 5W-40 maintains outstanding performance at high temperatures. It is also fully compatible with conventional oils. The key benefits include:

*Relative to conventional 15W-40 engine oil. Actual fuel economy improvement is dependent on vehicle/equipment type, outside temperature, driving conditions and your current fluid viscosity.

Meets or exceeds demanding specifications of major OEMs : One engine oil for mixed fleet operations
Outstanding thermal and oxidation stability : Control of low temperature sludge build-up and high temperature deposits
Low volatility, excellent wear and bore polish control : Good oil consumption control
Expertly formulated low viscosity formulation : Fuel economy potential*
Exceptional low temperature pumpability : Easier engine start-up and reduced wear
Good resistance to corrosion : Helps towards long life of critical wear surfaces
Long drain capability : Help towards operational efficiency andoverall cost control
Component compatibility : Long gasket and seal life, extended service intervals

Features and Benefits

High output, low emission diesel engines significantly increase the demands on engine lubricants. Tighter engine designs reduce oil consumption, resulting in less fresh oil make-up to replenish depleted additives. Top piston fire rings are located higher on the piston bringing the oil film closer to the combustion chamber where higher temperatures increase thermal stress on the lubricant. Increased fuel injector pressure and retarded timing improve fuel burn efficiency, but also increase engine temperatures and increase soot loads. Mobil Delvac MX 15W-40 is formulated from high performance base oils and a superior balanced additive system to provide optimum engine performance in modern diesel and gasoline engines as well as older models.

Key features and potential benefits include:

High thermal and oxidation stability : Reduced sludge build-up, deposits and viscosity increase
TBN reserves : Deposit control and acid neutralisation
Stay-in-grade shear stability : Wear protection and viscosity control
Advanced detergency/dispersancy : Cleaner engines and longer component life
Improved soot handling : Improved viscosity control and used oil pumpability
Excellent low temperature properties : Start-up wear protection
Component compatibility, Meets demanding specifications of key OEMs : Longer gasket and seal life, One engine oil for mixed fleet operations
