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
Long service life of seals, longer maintenance intervals
Low volatility, excellent control of wear and cylinder wall polishing
Good control of oil consumption
