Diesel fuels are refined petroleum products used mainly in compression ignition engines, industrial machinery, and power generation. They vary by grade, sulfur content, and application.
Diesel D2 (also called Gas Oil) under GOST 305-2013 is a Russian fuel standard used for ultra-low sulfur diesel fuel. It's primarily used in dieselengines for vehicles, generators, and industrial machinery.
Diesel D2 under GOST 305-82 is an older Soviet/Russian diesel fuel standard used mainly before the update to GOST 305-2013. It’s a middle distillate fuel used in diesel engines for vehicles, generators, and machinery. Still referenced in some export contracts, especially from Russian and CIS suppliers.
Important Note:
Because GOST 305-82 allows higher sulfur content, it's not compliant with modern Euro 4–6 standards. Many countries have phased it out for road use.
D2 Gas Oil EURO 4 is a diesel fuel that meets European Emission Standard Euro 4, with sulfur content limited to 50 ppm (parts permillion). It’s used in diesel engines and is cleaner than older D2 grades due to lower emissions.
Diesel D2, also known as Automotive Gas Oil (AGO), is a middle distillate fuel used in diesel-powered vehicles and machinery. It's a refined petroleum product used globally in transportation, agriculture, industry, and power generation.
D6 diesel, also called Residual Fuel Oil or Bunker Fuel, is a heavy fuel oil used mainly in large industrial engines, ships, and power plants. It’s much thicker than other diesel types like D2 or D4 and often requires preheating before use.
Important Note:
D6 is not suitable for automotive use due to its heavy composition. It's regulated heavily in ports and countries with environmental laws (e.g. MARPOL Annex VI).
D6 Virgin Low Pour Fuel Oil is a heavy residual fuel oil used in industrial boilers, large engines, and marine vessels. The term “Virgin” means it’s not blended with waste or reprocessed oils. “Low Pour” refers to enhanced cold flow properties, making it usable in cooler climates without excessive preheating.
EN590 is the European standard for diesel fuel used in road vehicles. It defines the physical and chemical properties of diesel to ensure engine compatibility and low emissions. The most common form today is ULSD (Ultra-Low Sulfur Diesel).
ULSD Euro 5 (10 ppm) is a high-grade diesel fuel with maximum 10 parts per million sulfur, designed to meet the Euro 5 emissionsstandard. It's used in modern diesel engines with advanced emission control systems (like DPF and SCR).
