Diesel fuel testing from SGS – meet industry and regulatory requirements for processing, selling and distributing diesel fuels.

Oil refinery

If you process, sell, or distribute diesel fuels, ensuring these fuels meet industry and regulatory requirements is vital to your business. We offer a full range of diesel fuel quality testing services to support refiners, traders, distributors, fleet owners and other customers.

Why choose diesel fuel testing from SGS?

Diesel fuel (distillate oil) testing and inspection services help with quality monitoring and compliance with regulations, and troubleshoot problems caused by biodiesel blending, trace metals, trace sulfur compounds and other challenges to fuel quality.

Testing capabilities include the analysis of ultra-low sulfur diesel (ULSD), biodiesel blends and more. Our laboratories provide testing to ASTM D975 (Standard Specification for Diesel Fuel Oils) and other recognized industry standards.

We also offer diesel fuel sampling, bulk cargo trade inspection, cargo blending, in-depth laboratory analysis, and cargo additive treatments.

Our diesel fuel analysis labs are open 24/7, with locations in key refining and distribution regions in the USA and around the world. We test all highway and off-road diesel fuels. Other distillate fuels that we test and inspect include No. 1, No. 2, and No. 4 fuel oils.
