Our Diesel Fuel Testing Services Include:

1. Fuel Quality Testing
   Ensure your diesel fuel meets the manufacturer’s recommended quality standards and is free from contaminants. Our testing checks for:

• • Water Content – Excess moisture can cause fuel to degrade and damage engines.
  • Particulate Contamination – Our test analysts can detect harmful particulates and contaminants that clog filters and affect engine performance.
  • Viscosity & Density – Clark’s viscosity and density test services evaluate the fuel’s consistency and flow characteristics to prevent engine issues.
  • Cetane Number – The cetane number affects ignition quality, combustion efficiency, and engine power.
  • Heat Value – The heating value measured in Btu/lb., is crucial in indicating the heat energy that can be extracted from a given weight of diesel fuel.

2. Fuel Performance Testing
   Clark’s Fuel & Lubrication lab verify efficiency and combustion characteristics of diesel fuel to assess maximize engine performance. Tests include:

• • Combustion Efficiency – Testing how effectively the fuel burns and powers your engines.
  • Energy Content – We provide evaluation of the calorific value of fuel to predict performance and economy.
  • Lubricity – Testing services also include fuel’s ability to prevent friction and wear on engine components.

3. Compliance and Regulatory Testing
   Clark’s ISO 17025 accredited analytical testing services helps companies with compliance in meeting regulatory guidelines with national and international fuel standards. We conduct testing in accordance with:

• • ASTM and ISO Standards – For meeting specifications set by global governing bodies.
  • Emission Standards – Testing fuel for low emissions and compliance with environmental requirements.

4. Additive and Treatment Effectiveness
   We also provide analysis of fuel additives or treatments, our lab can analyze their impact on fuel performance and engine efficiency. Our tests include:

• • Additive Compatibility – Ensuring additives are properly integrated and don’t interfere with fuel properties.
  • Fuel Stability – Testing the fuel’s ability to remain stable over time, especially with stored or aged fuel.

5. Microbial Contamination Testing
   Protect your fuel storage from biological contamination. We test for:

• • Microbial Growth – Detecting harmful bacteria or fungi that could cause fuel degradation and clogging.
  • Fuel Degradation – Identifying signs of oxidation and other breakdowns caused by microbial activity.

6. Diesel Fuel Storage and Handling Tests
   We help ensure that your fuel storage practices are safe and efficient. Our tests assess:

• • Storage Tank Contamination – Checking for contaminants in storage tanks that can compromise fuel quality.
  • Temperature Effects – Analyzing how temperature fluctuations affect fuel properties and performance.
