Motorists across South Africa (SA) are being urged to stay alert following a rise in the sale of adulterated diesel, commonly known as “dirty fuel”, which is being mixed with other substances to boost profits.

The fuel is often blended with products such as paraffin and industrial solvents, allowing sellers to cut costs and sell at lower prices while pocketing the difference, according to industry experts.

A 2024 investigation by the Department of Mineral Resources and Energy found that several petrol stations nationwide had been supplying contaminated diesel to unsuspecting customers.

The warning comes at a time when fuel prices are under pressure, partly due to instability in the Middle East, which has pushed up global oil costs.

Speaking on the issue, Chief Executive Officer of the Fuels Industry Association of South Africa, Avhapfani Tshifularo, said the lack of government regulation on diesel retail pricing has created room for abuse.

He explained that unscrupulous suppliers take advantage of price-sensitive motorists by offering unusually cheap fuel that has often been blended with lower-cost hydrocarbons.

“They will buy solvents or paraffin and mix it with normal diesel in bulk,” he said, adding that the practice is designed to undercut legitimate fuel prices and mislead consumers.

Authorities are urging motorists to be cautious when purchasing fuel that is significantly cheaper than the market rate, as it may indicate contamination that can damage engines and increase long-term repair costs.
