Heavy-Duty Diesel Engine Oils (HDDEO)

Reliable Protection for Commercial Fleets, Mining, and Power Generation

Heavy-duty diesel engines work under extreme loads, long operating hours, and harsh conditions. To keep them performing at their best, LUBELINE™ supplies premium Heavy-Duty Diesel Engine Oils (HDDEO) from leading global brands like Shell, Fuchs, and Engen. Our oils are engineered to deliver superior protection, extended drain intervals, and maximum reliability for trucks, buses, mining equipment, and power generation systems such as diesel generators.

Common Grades of Heavy-Duty Diesel Engine Oils

Choosing the right oil grade is vital for optimal performance and engine life. LUBELINE™ offers a wide range of viscosity grades, including:

• 15W-40 – the most common grade, suitable for mixed fleets and general heavy-duty applications.
• 10W-30 – provides improved cold-start performance and better fuel economy.
• 5W-40 – synthetic grade for extreme temperature ranges and modern high-output engines.
• 20W-50 – used in older engines or applications requiring higher viscosity.

Our HDDEO range also meets and exceeds API service categories such as CK-4, CJ-4, CI-4, and CH-4, ensuring compatibility with modern emission systems (EGR, DPF, and SCR technologies).

Applications of HDDEO

LUBELINE™ Heavy-Duty Diesel Engine Oils are formulated to perform across diverse industries and applications:

• On-road fleets – trucks, buses, and delivery vehicles.
• Off-road equipment – construction, mining, and agricultural machinery.
• Power generation – diesel generators requiring reliable lubrication for continuous operation.
• Marine and industrial engines – where durability and long service intervals are critical.
