Diesel Fuel Testing

Diesel fuel testing is a critical component of any fuel management program. Diesel fuel is inherently unstable and susceptible to contamination. It breaks down over time and forms gums, varnishes and sludge. It is contaminated by water that is introduced into the fuel system by condensation. Poor handling and storage practices can also result in water contamination. These factors make regular fuel testing absolutely necessary.  

We conduct countless tests each year to help you properly treat your diesel fuel and maximize its performance. The most common tests we conduct are listed below.
