Diesel Testing Services and Fuel Quality Analysis

Providing ISO/IEC 17025 accredited Diesel Testing Services for Ultra-Low Sulfur Diesel (ULSD), marine gas oil, and backup power fuel reliability.

Quality Assurance for Ultra-Low Sulfur Diesel (ULSD)

AGT Labs provides professional Diesel Testing Services to verify the combustion performance, cleanliness, and regulatory compliance of diesel fuel stocks. Our Houston facility specializes in high-resolution analytical profiling, performing sulfur speciation, cetane index calculation, and microbial contamination checks to ensure your fuel meets ASTM D975 and EPA ULSD standards.

Our analytical services support transport fleets, backup power facilities, and marine operators with accredited technical data. Whether verifying long-term storage stability for emergency generators or ensuring lubricity compliance for modern high-pressure common rail engines, we offer the precise results needed to prevent injector failure and costly downtime.

Containers & Handling

  • Use certified clean containers; opaque bottles recommended to prevent light degradation.
  • Take bottom, middle, and top samples from storage tanks to detect stratified water or sludge.
  • Seal immediately to prevent external moisture or dust contamination.

Transport & Logistics

  • Include accurate records of sampling location (tank bottom vs. nozzle) for technical interpretation.
  • Expedited shipping to our Houston laboratory for urgent generator fuel checks.
  • Samples stored in a cool environment per technical safety compliance standards.

Quality & Reporting

Reports from our laboratory testing provide technical clarity for engine warranties and regulatory audit compliance.

  • ✓ COA with method references, results, and certified authorized signatory.
  • ✓ Secure PDF Delivery via automated client technical portal.
  • ✓ Measurement uncertainty data for critical sulfur spec limits.
  • ✓ Consultation for off-spec flash point or water remediation.

Frequently Asked Questions

Can you detect microbial growth in stored fuel?
Yes, we offer screening for bacteria and fungi ('diesel bug'). Early detection is vital for preventing filter plugging and tank corrosion in backup generators and storage tanks.
How fast can I get diesel purity results?
Routine analysis via our Diesel Testing Services is typically delivered within 24 to 48 hours. We offer expedited rush support for Houston-area critical power and marine fueling operations.
What indicates poor long-term storage stability?
High water content (ASTM D6304), presence of particulates (ASTM D4176), and increased acidity (ASTM D1613) are key indicators of fuel degradation. We monitor these trends to recommend timely fuel polishing.
