EN590 diesel is a European standard that establishes specifications for automotive diesel fuel, encompassing aspects such as fuel composition, sulfur content, cetane number, density, viscosity, cold flow properties, lubricity, stability, and compatibility with biodiesel blends.

Compliance with the EN590 standard is crucial for ensuring the quality and performance of diesel fuel while adhering to environmental regulations. It contributes to reduced emissions and enhanced engine efficiency.

The production of EN590 diesel involves refining crude oil and hydrotreating to eliminate impurities and sulfur. This may be followed by blending, as necessary, and is complemented by stringent quality control procedures. These steps guarantee that the diesel fuel adheres to the specific requirements of the EN590 standard, such as low sulfur content and precise viscosity and density metrics, ensuring optimal cold flow properties and biodiesel blend compatibility. The aim is to produce a cleaner, high-quality fuel that supports reduced emissions and improved performance in diesel engines.
