Mobil Delvac 1 SHC 5W-40 

Mobil Delvac 1™ SHC 5W-40

Mobil Delvac 1 SHC 5W-40 is a very high performance, synthetic diesel engine oil that provides excellent lubrication including long drain capability, helping towards long engine life for diesel engines operating in severe applications. The advanced technology behind this product delivers exceptional performance in turbo-charged as well as older naturally aspirated engines. Mobil Delvac 1 SHC 5W-40 is recommended for use in a wide range of heavy-duty applications and operating environments found in trucking, mining, construction, agriculture and marine.

Modern high output diesel engines run hotter than older engines which significantly increases the demands on engine 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 where temperatures increase thermal stress on the lubricant. Mobil Delvac 1 SHC 5W-40 helps to protect the engine under severe operating conditions. It is also fully compatible with conventional mineral oils. The key benefits include:

FeaturesAdvantages and Potential Benefits
Excellent thermal and oxidation stabilityControl of low temperature sludge build-up and high temperature varnish deposits
High TBNHelps towards extended drain intervals with high sulphur fuels
Advanced formulation and viscometricsMaintains viscosity in severe, high temperature service
Excellent low temperature pumpabilityEasier engine start-up and reduced wear
Good resistance to corrosionHelps towards long life of critical wear surfaces
Long drain capabilityHelps towards good operating efficiency and lower overall cost
Component compatibilityLong gasket and seal life, extended service intervals
Low volatility, excellent wear and bore polishing controlGood oil consumption control
