Conidia FUELSTAT Plus – Rapid Diesel Microbial Contamination Testing
Test Diesel Fuel for Microbial Contamination in 15 Minutes
Microbial contamination can develop in diesel storage and fuel handling systems, particularly where water is present. Bacteria and fungi associated with fuel contamination can contribute to sludge formation, blocked filters, corrosion and fuel system reliability problems.
Conidia FUELSTAT Plus provides a practical method of testing for selected fuel-degrading microorganisms directly on site, without the delays associated with laboratory culture-based testing.
Designed for use in diesel and middle distillate fuel environments, the test helps operators assess microbial contamination as part of a structured fuel quality monitoring and maintenance program.
Why Choose FUELSTAT Plus?
Rapid On-Site Results
Obtain a microbial contamination test result in approximately 15 minutes, enabling faster decisions about further investigation and fuel system maintenance.
Targeted Microbial Detection
The test uses antibody immunoassay technology to detect groups of microorganisms associated with fuel degradation, including bacteria, fungi and Hormoconis resinae.
Practical Field Testing
The kit is designed for use in operational fuel environments and can be completed by personnel following the manufacturer’s sampling and test instructions.
Digital Results and Recordkeeping
The FUELSTAT Result app provides digital result verification and supports recording, reporting and retaining test results.
Applications
FUELSTAT Plus is relevant to a wide range of diesel fuel users and storage operators, including:
- Marine diesel tanks and commercial vessel fuel systems.
- Backup generator and emergency power fuel storage.
- Mining, construction and heavy equipment operations.
- Transport depots and commercial fleet fuel tanks.
- Bulk diesel storage and fuel distribution facilities.
- Industrial and critical infrastructure fuel systems.
What Does the Test Detect?
FUELSTAT Plus is designed to detect defined groups of fuel-degrading microorganisms, including bacteria, fungi and Hormoconis resinae.
The test provides semi-quantitative contamination classifications. It is not a complete analysis of all fuel quality parameters and does not replace testing for water, particulate contamination, chemical condition or other fuel properties when required.
How Does FUELSTAT Plus Work?
- Collect a representative fuel sample using the manufacturer’s sampling procedure.
- Prepare and extract the sample in accordance with the current kit instructions.
- Apply the specified drops of extracted sample to the test plate.
- Allow the test to develop for the prescribed period.
- Interpret and record the result using the manufacturer instructions or FUELSTAT Result app.
Sample collection and preparation time is additional to the published 15-minute test result time.
What’s Included?
Each standard test kit contains the testing components and sample extraction materials described in Conidia’s current instructions, including the test plate, sample extraction bottle, syringe, extraction tube and instruction leaflet. Packaging contents should be checked against the supplied production batch.

FUELSTAT Plus and Fuel Quality Management
Microbial contamination testing can form an important part of an effective fuel quality management program.
An identified contamination concern may require further sampling, water management, tank inspection, maintenance or an appropriately selected corrective treatment.
Fuel Right Australia offers fuel quality treatment products that may support wider fuel maintenance strategies, subject to product suitability and the condition of the fuel system.
Frequently Asked Questions
Can FUELSTAT Plus detect diesel bug?
Yes. FUELSTAT Plus is designed to detect selected groups of fuel-degrading microorganisms associated with microbial contamination, often referred to as diesel bug.
How quickly does the test work?
The test provides results in approximately 15 minutes after the required sample preparation and application steps.
Conidia Bioscience
Do I need to send my fuel to a laboratory?
No laboratory is required to perform the FUELSTAT Plus field test. Additional laboratory analysis may still be appropriate where further diagnosis or confirmation is needed.
Does FUELSTAT Plus treat contaminated fuel?
No. FUELSTAT Plus is a diagnostic test, not a fuel additive or microbial treatment.
Can I use FUELSTAT Plus for aviation fuel?
Conidia supplies aviation-specific FUELSTAT Plus kits. The diesel version should not be substituted for the aviation-specific product without manufacturer confirmation.
Does a negative result mean my diesel fuel is completely clean?
No. The test targets defined microbial groups and does not establish that fuel is free of all contaminants or meets every fuel quality specification.
