Features and Functional Benefits

The performance profile of 5W-30 multi-grade Diesel is designed to address key challenges faced by modern diesel engines. Advanced anti-wear additives help reduce metal-to-metal contact in heavily loaded components such as camshafts, bearings, and piston assemblies. This contributes to reduced wear and improved engine reliability over extended operating periods.

Enhanced oxidation resistance limits oil thickening and helps control the formation of sludge, varnish, and deposits. The detergent–dispersant system effectively manages soot and combustion by-products, keeping contaminants suspended in the oil and preventing harmful deposit formation. These characteristics support stable lubrication performance and help maintain engine cleanliness during extended drain intervals.

The formulation is also designed to maintain compatibility with modern exhaust after-treatment systems, including EGR, DPF, and SCR technologies, when used in accordance with engine manufacturer recommendations.

Technical Performance Characteristics

The technical performance of 5W-30 Diesel is supported by physical and chemical properties evaluated using recognized ASTM and DIN test methods. Typical characteristics are balanced to ensure reliable lubrication under varying operating and climatic conditions.

• KV40 and KV100 values are formulated to support efficient oil flow at low temperatures and adequate film thickness at operating temperature.
• A high Viscosity Index limits viscosity variation across temperature changes, supporting consistent lubrication performance.
• A controlled Pour Point ensures reliable low temperature pumpability.
• A high Flash Point indicates strong resistance to evaporation and thermal degradation under severe conditions.
• Density is maintained within a stable range to support formulation consistency and predictable oil behavior.
• An appropriate TBN level supports the neutralization of acidic combustion by-products, contributing to corrosion protection and oil longevity.

Applications and Engine Compatibility

5W-30 Diesel is suitable for a wide range of diesel-powered vehicles and equipment. In light-duty applications, including diesel passenger cars and light commercial vehicles, it supports smooth cold starts and stable lubrication during daily driving and highway operation.

For heavy-duty vehicles such as trucks and buses, the formulation provides robust oil film strength under sustained load and high operating temperatures. The product is also suitable for off-road diesel machinery used in construction, agriculture, and industrial operations, where engines operate under low-speed, high-load conditions and variable environmental stress.

Standards and Industry Alignment

This grade is formulated to meet API CK-4 performance requirements, indicating suitability for high-speed four-stroke diesel engines designed to comply with modern emissions regulations. The formulation philosophy aligns with performance principles applied by major global lubricant brands and is developed using industry-recognized ASTM and DIN testing procedures to ensure consistency and repeatability.

Packaging Options

To accommodate different operational and logistical requirements, 5W-30 Diesel is available in multiple packaging formats. Automotive and light commercial users can select 1L, 4L, and 5L packs. For workshops and service centers, 20L and 25L containers are offered. Drum packaging is available for fleet operators and industrial-scale consumption, supporting efficient storage and handling.
