Description
Product Introduction
T398 is an efficient anti-wear additive specially developed to enhance the lubrication performance of modern low-sulfur diesel. Through scientific molecular design and process optimization, it significantly improves the lubricity of diesel and effectively protects the precision components of the engine’s fuel system. It is particularly suitable for high-quality low-sulfur diesel (National VI and above) that has experienced a decline in lubricity due to deep desulfurization and hydrorefining.
Product Features
- Outstanding Lubricity Improvement: Significantly restores oil film strength in ULSD.
- Excellent Friction Reduction: Minimizes wear on fuel injection pumps and nozzles.
- Good Rust and Corrosion Inhibition: Protects metal surfaces within the fuel system.
- High Stability: Outstanding oxidation stability for long-term storage.
