Report suspected fuel adulteration in South Africa safely and securely. Fuel adulteration may involve the deliberate or reckless mixing, dilution, substitution or alteration of petrol or diesel so that the product supplied is not what was represented, ordered or paid for.
When to report suspected fuel adulteration
Report concerns where there are credible indicators such as unusual product characteristics, unexplained density results, repeated filter blockage, abnormal smoke or performance, broken seals, inconsistent delivery records, suspicious source documentation or other evidence suggesting the fuel may have been altered or substituted.
No single symptom proves adulteration. Report facts and observations rather than making public accusations.
Information that can help assessment
- Supplier, service station, depot or delivery location.
- Date, time, product and quantity involved.
- Invoice, receipt, delivery note or batch information.
- Vehicle, tanker, pump or tank identifiers where relevant.
- Lawfully obtained photographs, laboratory results or inspection records.
- A clear chronology of what you observed and how you became aware of the concern.
Preserve evidence responsibly
Keep original documents and files unchanged wherever possible. Do not trespass, impersonate another person, intercept communications or place yourself in danger to obtain a sample or photograph.
