D2 Diesel | High-Quality Gasoil Supply | Petroleum Products

D2 Diesel, also known as Gasoil (Diesel Fuel Grade 2), is one of the most widely used petroleum fuels in global transportation, industrial operations, and power generation. As a mid-distillate refined product derived from crude oil, D2 Diesel provides high energy efficiency, strong combustion performance and reliable operation for heavy-duty machinery. At PetroBNX, we supply premium-grade D2 Diesel that meets international specifications, ensuring stable performance, low emissions and consistent quality for industrial and commercial applications.

This page offers a comprehensive overview of D2 Diesel—its specifications, applications, quality standards, benefits and supply capabilities.

What Is D2 Diesel?

D2 Diesel is a type of middle distillate petroleum fuel classified under the ASTM Diesel Fuel Grade 2 standard. It is produced from the fractional distillation of crude oil and refined to provide clean-burning fuel suitable for engines requiring higher torque and power output.

D2 Diesel is commonly referred to as:

Gasoil

Diesel Fuel (Grade 2)

EN590 Diesel (for European standards, with variations)

Automotive Diesel Fuel

Low-Sulfur or Ultra-Low Sulfur Diesel (depending on sulfur content)

Because of its stability, energy density and compatibility with global diesel engines, D2 remains one of the most essential refined fuel products worldwide.

Types of D2 Diesel

Depending on the sulfur content and regional fuel regulations, D2 Diesel is categorized into different grades:

1. Standard D2 Diesel

Traditional D2 with higher sulfur levels (up to 0.5% or 5000 ppm) primarily used in:

Older engines

Industrial equipment

Off-road machinery

Power generation stations

This grade is common in regions where sulfur regulations are less strict.

2. Low Sulfur Diesel (LSD)

Contains sulfur content below 500 ppm.
Used widely in transportation and industrial equipment requiring cleaner fuel.

3. Ultra Low Sulfur Diesel (ULSD)

Contains less than 15 ppm sulfur.
Used in modern engines with emission control systems.

ULSD provides:

Reduced particulate emissions

Lower SOx formation

Better compatibility with global environmental standards

4. Winterized Diesel (Cold-Climate Grade)

Modified to prevent gelling and waxing in cold temperatures.
Typically used in Northern regions, mountainous areas and extremely cold climates.

Key Specifications of D2 Diesel

The specifications of D2 Diesel may vary by origin, refinery and supply contract, but typical international standards include:

Sulfur content: 15 ppm – 5000 ppm (depending on grade)

Flash point: 55°C minimum

Cetane number: 40 – 55

Density @ 15°C: 0.82 – 0.86 g/cm³

Water & sediment: < 0.05%

Viscosity: 1.9 – 4.1 cSt

Color: Clear to pale yellow

At PetroBNX, each batch is accompanied by:

Certificate of Quality (COQ)

Technical Data Sheet (TDS)

SGS or equivalent inspection reports (on request)
