10ppm diesel now at 20 Cape Sasol sites: which diesel your car needs
Sasol now sells 10ppm diesel at 20 Western Cape sites, replacing 50ppm. Here is the list, how 10ppm compares with 50ppm and 500ppm, and why it becomes the national standard on 1 July 2027.
Sasol has started selling its 10ppm diesel at 20 participating service stations in the Western Cape, where it replaces 50ppm diesel at the pumps, the company said on 6 November 2026 (Sasol). The grade is already sold inland and has been available in KwaZulu-Natal since 2024 (Sasol).
If your diesel car is fairly new and has modern exhaust after-treatment, this is the fuel it was built for. And from 1 July 2027 all petrol and diesel sold in South Africa must meet the 10ppm sulphur limit anyway (Fuels Industry Association of South Africa).

What does 10ppm actually mean?
It's the amount of sulphur in the fuel: no more than 10 parts per million (Sasol). Less sulphur means the fuel works with the particulate filters and catalytic systems fitted to many newer diesel vehicles and helps keep them working properly (Sasol).
500ppm, 50ppm or 10ppm: which diesel does your car need?
| Grade | Who it's for | The catch |
|---|---|---|
| 500ppm | Older, simpler diesel engines and mostly commercial use | Not suitable for diesel particulate filters and modern exhaust systems |
| 50ppm | Most diesel vehicles on the road | Not ideal for the newest engines |
| 10ppm | Modern diesels with particulate filters and SCR systems | Costs more per litre, and older engines gain little |

The South African's motoring desk sums it up this way: if you drive a modern diesel with a particulate filter, 10ppm is the grade your engine was designed for, while an older mechanical diesel is fine on 50ppm and 10ppm won't hurt it (The South African). Your vehicle's manual or fuel flap label will say which grade the manufacturer specifies.
Is 10ppm diesel more expensive?
The South African notes it costs more per litre than lower grades (The South African). Sasol did not give a price in its release, so check the pump price at your garage (Sasol).
When does 10ppm become the rule everywhere?
On 1 July 2027. A notice signed by the then Minister of Mineral Resources and Energy, Gwede Mantashe, moved the start date of the fuel specification regulations from 1 September 2023 to 1 July 2027 (Government notice R. 2184 of 2022). Under these rules, known as Clean Fuels II, petrol and diesel may contain at most 10ppm of sulphur (Fuels Industry Association of South Africa).
The deadline has slipped before. The rules were first meant to start on 1 July 2017 (Fuels Industry Association of South Africa).
Why does it matter for new cars?
The industry body says the cleaner fuel will let new vehicle technology reach Euro 5 tailpipe emission standards, and refiners have spent billions of rand on upgrades to be ready for 2027 (Fuels Industry Association of South Africa).
