Fuel testing services investigate stored fuel for a defined concern. The tests are selected for the fuel, the equipment it supplies and the problem being investigated rather than using one result as a general certificate of quality.
Fuel Testing Services
Fuel testing services investigate the condition of stored fuel and the cause of a specific concern.

Representative fuel samples
Sampling location and method affect what the laboratory results can show about stored fuel.
The intended fuel use
The test schedule needs to address the fuel specification or contamination concerns relevant to the equipment served.
Different tests answer different questions
Particle count, water measurement and microbial analysis answer different questions. A satisfactory result in one area does not establish that every other fuel property meets the requirement for its intended use.
Storage history can change the investigation. Long storage, an unexpected delivery, repeated filter blockage or known water ingress may point to different tests or sampling locations.

Sampling location and timing
A sample represents the place and time from which it was taken. Fuel near the normal outlet can differ from water, sludge or sediment at the bottom, so the sampling plan needs to match the question being asked.
Sampling must be carried out without unsafe opening, entry or exposure to uncertain contents. The results need to identify what was tested and the criteria used to interpret them.
Using the results
A failed result does not by itself determine the treatment. The response depends on the property affected, the condition of the tank and the intended fuel use. A clear-looking sample is not proof that the whole tank contains suitable fuel.
Fuel Testing Services: common questions
Does a clear fuel sample prove it is suitable for an engine?
No. Appearance cannot establish all contamination or fuel-property requirements. The appropriate tests and equipment criteria need to be considered.
Can one sample describe the whole tank?
Not always. Water and sediment can be unevenly distributed. The sampling plan should reflect the tank layout and the question being investigated.
Will a test report tell me whether polishing will work?
It can help identify removable contamination, but the treatment decision also depends on the fuel condition, tank deposits and intended use.
Will a particle count establish microbial contamination?
No. It addresses particles, while microbial investigation requires a suitable separate method. The tests should follow the suspected problem.
When can storage history change the testing plan?
Long storage, an unexpected delivery, repeated filter blockage or known water ingress can point to different tests or sampling locations.
