Complete Testing Services

Corrigan Labs conducts a broad range of fuel, oil, DEF, and ethanol blend tests using ASTM and ISO methods. We analyze fuels for volatility, contamination, additive presence, acidity, and more. Our in-house capabilities are further enhanced by partnerships with local labs for expanded testing options.

We commonly measure:

  • Flash point / fire point
  • Vapor pressure
  • Total Acid Number (TAN)
  • Water content (visual & Karl Fischer)
  • Ethanol and biodiesel content
  • Density, pHe, and conductivity
  • Metals such as copper, manganese, lead
  • IR scan for lubricant and additive analysis

Test results are delivered digitally and in print, with full Certificates of Analysis provided for custom blends.

Specialty Fuel Blending Capabilities

Corrigan Labs has earned a national reputation for its ability to custom-blend fuels to exacting standards. Our team formulates everything from high-octane and racing fuels to controlled vapor pressure blends and durability fuels used in long-term testing. We also specialize in ethanol-based products, including blends derived from both corn and sugar cane, as well as biofuel blends using diverse feedstocks.

We routinely develop fuels with specific additives such as MMT (methylcyclopentadienyl manganese tricarbonyl) or lead content, and we’re trusted by OEMs and independent labs to deliver accurate, repeatable results. Emission and legislative fuels are also within our blending portfolio, ensuring compliance with evolving regulatory environments.

Blending Flexibility

Corrigan’s blending operations range from 5 gallons to 30,000 gallons, with product available in drums, totes, or full transport loads. With over 100 on-site storage tanks, we can maintain a consistent batch for the full duration of your testing program.

DEF & Coolant Testing

Corrigan Labs offers comprehensive analysis of Diesel Exhaust Fluid (DEF) and engine coolants, both of which play a critical role in modern emissions and thermal management systems.

For DEF, we follow ISO 22241 standards, measuring urea concentration via refractive index, along with alkalinity, density at 20°C, and critical impurity levels such as biuret and aldehyde content. Our testing ensures compliance and helps customers avoid DEF-related system failures.

When it comes to coolants and antifreeze, we evaluate physical and chemical characteristics including boiling and freezing points, reserve alkalinity, pH, conductivity, and dilution accuracy. These tests are vital to maintaining equipment reliability across seasonal extremes and extended service cycles.
