South Africa’s Diesel Prices in the African Context
While South Africa’s diesel prices have been decreasing, they remain higher compared to several other African nations. For instance, in May 2025, countries like Libya and Algeria reported diesel prices as low as $0.027 and $0.218 per litre, respectively . This disparity underscores the varying fuel pricing structures across the continent.
