Why Does Fatty Acid Composition Matter in Diesel Lubricity Improvers?

Release time:

Nov 05,2026

Fatty acid-based additives play an important role in improving the lubricity of ultra-low sulfur diesel (ULSD).
However, performance depends on more than just acid value.
Key factors include:
✅ HFRR Performance – Effective wear protection at low treat rates.
✅ Fatty Acid Composition – Optimized oleic (C18:1) and linoleic acid (C18:2) profiles.
✅ Low-Temperature Stability – Low saturated fatty acid content helps reduce crystallization risks.
✅ Compatibility – Stable performance with diesel and other fuel additives.
At TIANYUAN, we focus on optimizing plant-based fatty acids for reliable diesel lubricity performance.
