Diesel Generator oil

Typical Properties

Property Typical Value Unit Notes
SAE Grade 15W-40 Multigrade oil for diesel engines
Density @ 15°C ~0.870 – 0.890 g/cm³ Indicates oil thickness and mass per volume
Kinematic Viscosity @ 40°C 100 – 120 cSt Affects flow at startup and lubrication at warm-up
Kinematic Viscosity @ 100°C 13.5 – 15.5 cSt Maintains film strength at operating temperature
Viscosity Index (VI) ≥130 High VI ensures viscosity stability across temperature changes
Pour Point ≤ –30 °C Minimum temperature at which the oil remains fluid
Flash Point (COC) ≥220 °C High flash point ensures safety at high engine temps
Total Base Number (TBN) 9 – 12 mg KOH/g Neutralizes acids and extends oil life
Sulfated Ash ≤1.2 % wt Related to detergent additives; affects emissions and deposits
Foaming Characteristics Pass (Seq I–III) Prevents foam formation in high-speed engine components
Shear Stability Excellent Resists viscosity breakdown in high-stress areas
Oxidation Resistance Excellent Prevents sludge and varnish under high temperatures

📋 Diesel Generator Oil

Type
High-performance diesel engine oil specifically formulated for use in diesel generators operating under varying loads and temperature conditions. Designed to deliver long engine life, oxidation stability, and extended drain intervals, especially in stationary and backup power generation systems.

Formulation

  • Made from premium-quality base oils (mineral or synthetic)
  • Fortified with a balanced additive package including detergents, dispersants, anti-wear agents, antioxidants, and corrosion inhibitors
  • Meets or exceeds API CH-4, CI-4, or CK-4 and OEM specifications depending on grade

Available SAE Grades

  • SAE 15W-40, 20W-50, and 30 are the most common
  • Multigrade options offer enhanced cold-start protection and high-temperature stability

Key Benefits
Superior Wear Protection
Prolongs engine component life, particularly for pistons, liners, and valve trains in high-load operations.

Thermal and Oxidation Stability
Prevents oil thickening and deposit formation, even under prolonged high-temperature use.

Soot and Sludge Control
Dispersant additives manage soot and contaminants, maintaining engine cleanliness.

Corrosion and Rust Protection
Protects internal components during both active operation and generator downtime.

Extended Drain Intervals
Reduces maintenance frequency, making it ideal for remote or critical power backup installations.

Low Volatility
Minimizes oil consumption and evaporative loss.

Applications

  • Diesel Generator Sets (DG sets) – Prime, standby, or emergency power units
  • Suitable for both turbocharged and naturally aspirated engines
  • Common in industries, hospitals, data centers, construction sites, telecom towers, and agriculture

Meets Performance Standards

  • API CH-4 / CI-4 / CK-4
  • ACEA E2 / E4 / E7
  • OEM Approvals (e.g., Cummins, Perkins, Volvo Penta, Caterpillar, Mahindra Powerol)

Packaging
Available in 5L, 7.5L, 10L, 20L, 50L, and 210L drums based on operational needs.
