### Seasonal Adaptability  

Established Supply Use Cases

Widely used across commercial, retail, and logistics environments.

Typical Applications

Diesel is used across multiple sectors where reliable fuel supply is required.

Technical Specifications

Diesel is defined by recognised standards and measurable performance characteristics. Compliance ensures consistent usability across engines and applications.

Standards and Approvals

Diesel supplied complies with BS EN 590. This standard defines requirements for road diesel fuels, including sulphur limits, density, and performance criteria.

Emissions Classification

ULSD contains a maximum of 10ppm sulphur. This supports compatibility with modern emissions control systems compared to higher sulphur fuels.

Chemical Composition

Diesel is a middle distillate fuel with controlled FAME content up to 7%. This distinguishes it from fuels with higher biodiesel concentrations.

Ignition Quality (Cetane Number)

Diesel is designed for compression ignition engines, enabling efficient combustion without spark plugs.

Cold Flow Properties

Seasonal grades are available. Winter diesel has a CFPP of -12°C max, while summer diesel is specified at -4°C max under BS2869.

Storage Stability

Diesel is suitable for standard storage conditions when handled correctly and within specification limits.

Product Variants

Diesel is available in different variants depending on regulatory use, taxation, and operational requirements. These variants ensure the correct fuel is used for specific applications.

FAQ

Is there a difference between on-road and off-road diesel fuel?

Yes, there are differences in taxation and permitted usage. On-road diesel (white diesel) is used for vehicles operating on public roads. Off-road diesel (gas oil or red diesel) is primarily used in agricultural and certain industrial applications. It is important to ensure the correct fuel type is used based on regulatory requirements and operational use.

Is there a difference between winter and summer diesel?

Yes. Diesel fuel is adapted to seasonal temperature conditions. Winter diesel has a cold filter plugging point (CFPP) of up to -12°C, supporting operation in lower temperatures. Summer diesel has a CFPP of up to -4°C. These specifications are defined under British Standard BS2869.

What is ULSD?

ULSD stands for Ultra Low Sulphur Diesel. It is a diesel fuel with a sulphur content of up to 10ppm. This specification supports compatibility with modern engines and emissions control systems.

Can diesel contain biodiesel?

Yes. Diesel can include up to 7% biodiesel (FAME content). This blending is defined within the BS EN 590 standard and ensures compatibility with engines designed for standard diesel fuels.

What industries use diesel fuel?

Diesel is widely used across transport, construction, agriculture, logistics, and fuel retail sectors. Its versatility makes it suitable for both mobile and stationary applications.

Do you supply diesel in bulk?

Yes. We supply diesel in bulk quantities to commercial and industrial customers. Delivery volumes and schedules can be aligned with your operational requirements.
