Certified for the toughest diesel engines — now trusted by Cummins

Eurotec announces a significant advancement in its heavy-duty lubricant portfolio: Eurotec Maximizer

15W-40 CK-4 has officially been approved by Cummins Inc. under CES 20086 specification — a critical endorsement confirming its performance and compatibility with Cummins' latest generation of highefficiency diesel engines.

This approval reflects Eurotec’s continued commitment to developing lubricant technologies tailored to the operational realities of modern diesel engine systems used across transportation, construction, industrial, agricultural, and off-road sectors.

Cummins CES 20086: A New Benchmark for Diesel Lubrication

Today’s diesel engines are built for increased output, longer service intervals, and lower emissions. CES 20086 is Cummins’ most advanced lubricant performance specification — designed to ensure engine oils support these expectations without compromise.

Unlike baseline industry standards, CES 20086 validation includes intensive testing under:

• Sustained high-temperature conditions
• Heavy soot load cycles
• Dynamic high-RPM operating ranges
• Exhaust aftertreatment system interaction

Passing this rigorous protocol confirms that Eurotec Maximizer 15W-40 CK-4 delivers stable, highperformance lubrication under realistic engine stress conditions — including compatibility with DPF, SCR, and EGR systems.

Eurotec Maximizer 15W-40 CK-4: Engineered for Modern Diesel Performance

Purpose-built for advanced diesel platforms, this formulation incorporates a well-balanced additive system and stable base oil structure. Its key performance characteristics include:

• Excellent oxidation control to resist viscosity increase and oil degradation
• Shear-stable viscosity retention for consistent protection over extended intervals
• Efficient soot handling to prevent buildup and maintain engine cleanliness
• Low SAPS formulation that protects emissions systems without sacrificing durability
• Comprehensive wear protection for pistons, liners, valve trains, and other high-load components

This balanced profile enables performance under both high-stress and mixed-duty conditions, supporting optimal engine life and fuel efficiency.

Trusted Across Heavy-Duty Applications

Eurotec Maximizer 15W-40 CK-4 is approved for use in a wide range of Cummins-powered applications, including:

• Freight and logistics fleets
• Construction and mining equipment
• Agricultural machinery
• Backup and base-load power generators
• Industrial marine propulsion systems

Its performance has been validated for long-haul highway operations, severe off-road cycles, and stationary engines operating under continuous or variable loads.

Tested Under Pressure. Approved for the Field.

Cummins CES 20086 approval is granted only after a lubricant successfully completes a series of rigorous, performance-critical tests. These include:

• Oxidative and thermal stability validation
• High-stress wear protection testing
• Soot dispersancy and deposit control evaluations
• Compatibility testing with sensitive aftertreatment systems

Eurotec Maximizer 15W-40 CK-4 met or exceeded every requirement — confirming its fitness for realworld deployment in both legacy and next-generation Cummins diesel engine architectures.

A Strategic Advantage for Maintenance Planning

Beyond its technical strengths, Eurotec Maximizer 15W-40 CK-4 offers operational benefits that directly impact fleet productivity. Its compatibility across multiple heavy-duty applications simplifies inventory and logistics, while its long-drain capability (when supported by oil analysis) helps reduce service frequency and total cost of maintenance.

EUROTEC – Liquid Excellence

Eurotec Maximizer 15W-40 CK-4 is more than just a lubricant — it’s a performance-proven solution, engineered to protect what matters and validated by one of the world’s most respected engine manufacturers.
