Specifications
Ultimate Wear Protection:
Advanced anti-wear additives form a resilient protective film on critical engine components, drastically reducing friction under extreme pressures.
Superior Soot & Sludge Control:
High-dispersion technology keeps soot in suspension, preventing harmful sludge buildup and maintaining clean oil galleries.
Excellent Thermal & Oxidation Stability:
Prevents oil thickening and breakdown even during prolonged high-temperature operations in harsh environments.
Corrosion & Rust Mitigation:
Neutralizes harmful acidic combustion byproducts to safeguard yellow metals and iron components inside your engine.
Optimized Fuel Efficiency:
The balanced 15W-40 formulation maintains stable oil pressure, optimizing engine efficiency and reducing oil consumption.
🌡️ Viscosity & Temperature Range Guide (15W-40)
"15W" (Winter): Provides reliable engine cranking and fluid flow down to -20°C (-4°F).
"40" (Hot Operating Rating): Retains excellent viscosity and thickness at standard engine running temperatures (up to 40°C / 104°F+ ambient temperature), ensuring the oil film does not shear or thin out under high workloads.
