ULSD & Diesel

ULSD & Diesel

Ultra-low sulphur diesel and gasoil for road transport, industry and power generation.

Middle Distillates

Product Overview

Diesel is a middle distillate used in compression-ignition engines. Ultra-low sulphur diesel (ULSD) combines low sulphur content with controlled ignition quality, lubricity and cold-weather performance. Gasoil grades serve a wider range of industrial and stationary applications.

Product Knowledge

Grades & Specification

EN 590 is a principal reference for European automotive diesel. Gasoil and other destination grades have their own specifications.

Performance Across Operating Conditions

Sulphur content is one part of diesel quality. Ignition performance, fuel-system protection and cold-flow behaviour are equally relevant. A summer diesel grade and a winter grade can have different low-temperature and density requirements.
