Product description
Mobil Delvac Ultra 5W-40 Ultimate Defense is an advanced synthetic ultra-performance diesel engine oil that provides excellent lubrication, enables long drain intervals and helps extend the life of heavily loaded diesel engines. The advanced technology of the oil enables excellent performance of turbocharged and older naturally aspirated engines. Mobil Delvac Ultra 5W-40 Ultimate Defense oil is recommended for use even in difficult conditions and heavily loaded applications in road and site driving, mining, agriculture and ships.

Benefits and features
Modern high-powered diesel engines run hotter than older engines, which significantly increases engine lubricant requirements. Engines designed to be tighter reduce oil consumption, but at the same time reduce the access of new replacement oil and additives to the engine. The top piston rings are closer to the combustion chamber than before, which increases the thermal load of the lubricant. Mobil Delvac Ultra 5W-40 Ultimate Defense helps protect engines operating in demanding applications. It is also fully compatible with conventional mineral oils. The main advantages are:

Excellent thermal stability and oxidation resistance

Controlled precipitate formation at low temperatures and varnish formation at high temperatures

High maternal number

Helps extend oil change intervals when using high sulfur fuels

Advanced formulation and viscosity properties

Maintains viscosity at high temperatures and demanding use

Excellent pumpability at low temperatures.

Easier startability of the engine and reduced wear

Good corrosion resistance

Helps extend the life of important wear surfaces

Possibility of long replacement intervals

Helps to achieve better operational efficiency and reduce overall costs

Compatible with different engine parts
