DIESEL FUEL CONTAMINATION

FUEL AND COMPREHENSIVE TANK STUDY (FACTS)

 ULTRA LOW SULFUR FIELD TEST

DIESEL FUEL STABILITY FIELD TEST

Herguth Laboratories, Inc. conducted a large detailed study of fuel oils for stand-by diesel generator operation.  The objective was to determine the difference between delivered fuels and those in storage.

Methods

Diesel fuel samples were analyzed using ASTM (American Society of Testing and Materials)  D975  "Standard Specifications for Fuel Oil." Test results showed that the fuel parameters addressed by this specification had minimal deviation between new and stored product.

Samples were also analyzed using ASTM D2274 "Stability of Fuel Oil" and ASTM D2276 "Filtration Cleanliness of Aviation Fuel."  These results showed a substantial difference between stored vs new fuel.

This study confirmed the common belief that stored fuel should be evaluated for degradation and contaminants on a regular basis. New fuel deliveries should be tested for quality, stability and cleanliness.

All deliveries of fuel should be evaluated using ASTM D975, D2276 and D2274.  Once fuel is placed in storage, it should be evaluated on a regular basis using the Herguth FACTS method.

GASOLINE AND TURBINE FUEL  

As with diesel fuel gasoiline and turbine fuel can be contaminated in transit or in storage.  Herguth provides comprehnsive to evaluate the type and levels of contamination.
