Diesel and Kerosene Analysis

Diesel and Kerosene Testing Services in Saudi Arabia

Know your fuel quality. Protect your equipment. Make informed operating decisions.

Environmental Testing and Laboratories Company (ETLCO) provides diesel and kerosene analysis to help fuel producers, suppliers, distributors, and industrial users assess fuel quality, verify product specifications, and investigate performance concerns.

From routine quality control to suspected contamination, our Oil & Gas Laboratory delivers testing tailored to the fuel type, intended application, and agreed specification. Our services support quality assurance during production and refining, verification before acceptance or use, and the investigation of storage and handling issues.

Why Test Diesel and Kerosene?

Fuel quality can affect equipment reliability, combustion performance, storage, and handling. Laboratory analysis helps identify variations or contamination that may not be apparent through visual inspection alone.

Diesel and kerosene testing helps you:

• Verify whether a fuel batch meets the agreed purchasing or product specification.
• Assess suitability for the intended equipment and operating conditions.
• Identify water, sediment, and other indicators of contamination.
• Investigate concerns such as poor ignition, filter blockage, deposits, or excessive smoke.
• Evaluate fuel condition following storage or transfer.
• Support quality documentation and applicable compliance requirements.

Diesel Fuel Analysis

Reliable equipment operation starts with understanding the fuel you use.

ETLCO supports diesel quality assessment for applications such as generators, transport fleets, construction equipment, and industrial operations.

We help clients evaluate fuel characteristics relevant to ignition quality, flow behavior, handling, and contamination. Testing can support incoming fuel acceptance, supplier quality checks, maintenance investigations, and the assessment of stored fuel before use.

Kerosene Quality Testing

Check the properties that matter for your kerosene application.

ETLCO provides kerosene testing to evaluate characteristics associated with volatility, combustion quality, handling, and cleanliness.

Our testing supports producers, distributors, and industrial users in assessing batch consistency, investigating suspected contamination, and comparing results with the specification relevant to the intended use.

Our Diesel and Kerosene Testing Capabilities

The testing program is selected according to the product and its intended application. Not every parameter is appropriate for both diesel and kerosene.

Testing area	Available parameters and assessment focus
Ignition quality	Cetane number for diesel fuel, where applicable.
Volatility and boiling characteristics	Distillation and boiling range distribution.
Viscosity and flow properties	Kinematic viscosity to assess fuel flow characteristics.
Low-temperature behavior	Cloud point, pour point, and cold filter plugging point, as applicable to the product.
Handling characteristics	Flash point and electrical conductivity, according to the relevant specification.
Kerosene combustion quality	Smoke point to assess the fuel’s tendency to produce smoke under specified test conditions.
Sulfur compounds	Total sulfur by energy-dispersive X-ray fluorescence (ED-XRF) and mercaptan sulfur.
Water and contamination	Water and sediment testing to help assess fuel cleanliness.
Residue and deposit-related properties	Ash content and gum content, where applicable.
Acidity	Total acid number to assess acidic constituents.
Appearance	Colour testing to support product consistency checks.
Composition	Detailed hydrocarbon analysis and oxygenates testing, where relevant to the product or investigation.

Additional parameters can be discussed with our laboratory team based on your testing objectives and the applicable method.

Testing for Routine Quality Control and Fuel Investigations

Fuel Batch Acceptance

Check incoming deliveries against agreed specifications before release, distribution, or use. A defined testing program supports consistent acceptance decisions and supplier quality management.

Production and Refinery Quality Control

Assess product consistency during production and refining, with testing selected to address the quality characteristics relevant to the finished fuel.

Stored Fuel Assessment

Evaluate diesel or kerosene following storage, particularly when water ingress, sediment accumulation, or changes in fuel condition are suspected.

Equipment Performance Investigations

When operating problems arise, targeted fuel analysis can help determine whether fuel characteristics or contamination may be contributing factors.

Suspected Mixing or Contamination

Investigate unexpected changes in fuel properties through a testing scope designed around the suspected issue and available sample information.
