ISOSYN® TECHNOLOGY – THE FOUNDATION BEHIND DELO’S SUPERIOR PERFORMANCE

What is ISOSYN®?

• ISOSYN is Chevron’s proprietary lubricant formulation technology, built upon the combination of premium base oils, high-performance additive systems, and the company’s advanced blending expertise and technical know-how.
• The objective of this technology is to create lubricant products that not only meet current technical standards but exceed them, delivering exceptional engine protection throughout operation.
• The foundation of ISOSYN begins with highly refined base oils produced through advanced purification technology, providing outstanding thermal durability and oxidation stability. Combined with high-performance additive systems, the lubricant gains enhanced soot dispersancy, reduced deposit formation, and effective viscosity control throughout the oil drain interval.
• This helps maintain engine cleanliness, reduce friction and wear, even under heavy loads or prolonged high-temperature operation.

Delo with ISOSYN® Technology – A Solution for More Durable Engine Operation

• Delo lubricants formulated with ISOSYN technology are designed to help users optimize operational efficiency while minimizing maintenance costs.

• Thanks to high oxidation stability and superior sludge control capability, the oil helps extend oil drain intervals, reduce maintenance frequency, and minimize unplanned downtime.
• In addition, ISOSYN technology enhances engine durability by protecting critical components such as piston rings, camshafts, crankshafts, and bearings against friction and high temperatures.
• As a result, operators can confidently run equipment at optimal performance while effectively controlling total operating costs throughout the equipment lifecycle.

Proven Performance Across Multiple Industries

Delo lubricants utilizing ISOSYN technology have been tested and proven effective through millions of kilometers of operation and tens of thousands of actual operating hours across various diesel engine platforms.

This technology is widely trusted across industries such as road transportation, agriculture, mining, construction, and marine operations, where engines continuously operate under heavy loads and harsh environmental conditions.

From transport vehicle owners and large fleet operators to construction machinery companies and marine operators, ISOSYN has consistently demonstrated stability, reliability, and long-lasting performance under diverse operating conditions.

Practical Benefits for Users

The application of ISOSYN technology in Delo products provides significant practical benefits through superior soot dispersancy and deposit control, helping maintain engine cleanliness throughout the oil lifecycle.

At the same time, the strong lubricating oil film effectively protects critical engine components against wear, minimizing damage and extending engine life.

More importantly, this technology gives operators confidence to run engines at high output for extended periods while maintaining equipment stability and durability, thereby improving operational efficiency and delivering long-term economic benefits.

ISOSYN® ADVANCED – The Next Generation of Advanced Technology

Building upon the success of ISOSYN, Chevron Corporation has developed the next-generation ISOSYN ADVANCED technology with major improvements in anti-wear protection, deposit control, and oxidation resistance.

This new-generation technology further enhances engine durability and reliability under increasingly severe operating conditions while extending oil drain intervals even further.

A typical example is Delo 400 SLK SAE 15W-40, formulated with ISOSYN ADVANCED technology.

The product helps extend engine life, provide superior component protection, and reduce total operating costs compared to previous generations of Caltex heavy-duty diesel engine oils.

As a result, businesses and operators can optimize maintenance costs, increase equipment uptime, and improve long-term investment efficiency.
