Fahrwunder 20W-50 Diesel Engine Oil 18L API CI-4 – OEM/ODM Heavy-Duty High-Viscosity

Fahrwunder 20W-50 Diesel Engine Oil 18 L API CI-4 delivers reliable, heavy-duty performance and protection across demanding diesel applications. Its 20W-50 high-viscosity formulation ensures robust lubrication stability under extreme temperatures and heavy engine loads. Available for OEM/ODM customization, this oil empowers commercial clients and auto brands to supply a high-quality, branded product tailored to specific fleet or industrial requirements.

Superior Film Strength for Extreme Conditions
The thick oil film inherent in the 20W viscosity grade remains intact in high-heat, high-stress scenarios. This provides essential surface protection for components during long-haul trips or heavy torque demands. Similar CI-4 oils are known for maintaining viscosity and avoiding breakdown under prolonged high-temperature operation. Reliable film stability reduces component wear and supports consistent engine performance.

API CI-4 Performance Tailored for Diesel Engines
As an API CI-4-certified oil, it is engineered to protect engines equipped with Exhaust Gas Recirculation systems and those operating under high soot and contamination conditions. CI-4 oils offer enhanced defense against ring and liner wear, soot-induced thickening, and oxidation impact. This makes them ideal for modern diesel engines facing tight emission compliance and extended service intervals.

Cleaner Engines, Extended Life
CI-4 diesel formulations are known for powerful dispersant and detergent action, combating sludge, varnish, and carbon deposits. This helps protect oil galleries, pistons, and rings, minimizing buildup that would otherwise degrade performance or require more frequent maintenance. Cleaner engines maintain efficiency and longevity, reducing operational costs for fleet operators and OEMs alike.

Cold-Start Fluidity Balanced with Heat Resistance
While 20W-50 is thicker than lower viscosity equivalents, top-tier formulations are often balanced to allow sufficient cold-crank capability while still delivering heat-resistant film stability at operating temperatures. This dual performance ensures reliable engine starting without sacrificing high-temperature protection.

Ideal for Heavy-Duty Diesel Platforms
This oil suits trucks, buses, agricultural machinery, mining equipment, and heavy-duty construction vehicles. It offers consistent protection in high-load, mixed-duty, and extreme-temp applications. It’s also backward-compatible with earlier diesel specifications, offering versatility across fleet types.

OEM/ODM Customization Advantages
Fahrwunder’s model is centered on flexibility for business clients. OEMs and distributors can:

·         Modify additive blends to meet specific engine types or regional fuel standards.

·         Apply private labeling and custom packaging that aligns with brand identity.

·         Set technical documentation and compliance in line with regulatory or warranty demands.

This allows clients to define distinctly branded, specification-aligned products for resale or integration into their own product lines.
