Diesel extra fuelmeets Dynaflex technology

By Dineo Phoshoko
The newly launched Dynaflex technology from Shell has reached South Africa’s shores. When added to Diesel Extra, the latest innovation in fuel technology has many benefits for the mining industry.

What is Dynaflex technology?

Dynaflex technology is the latest fuel innovation from Shell South Africa that is designed to help clean and protect engines. The Dynaflex fuel is made from new formulations that are designed and enriched with powerful cleaning agents that help to maintain the cleanliness of important fuel system components. In addition, the formulations also protect the fuel system components from performance robbing deposits.

Some key fuel system components that are protected from the formulations include intake valves and fuel injectors. When deposits build-up on intake valves and fuel injectors, the fuel spray does not mix well. Instead the fuel is unable to burn efficiently and results in a decrease in the performance of the fuel system components.

The effect that the new formulations could potentially have on the fuel system components may differ depending on a variety of factors such as the type of vehicle, its condition and the way it is driven regularly.

Shell Diesel Extra

Shell’s Diesel Extra (DE) is a fuel that is offered specifically to the commercial sector and differs from the retail offering. According to Shell South Africa’s product and channel optimisation manager, Nischal Sancho, DE is allocated to the mines especially for the specific benefits of cleaning, extra torque and pulling power. The Diesel Extra fuel has been especially designed to ensure enhanced detergency, prevent fuel system corrosion, and ensure good water separation. In addition, the fuel also assists with faster filling.

Diesel Extra fuel cleans up any deposits found on the injectors, and even prevents further build up in future. The DE fuel works while the engine is in operation, even over a long period. Additional benefits of the DE include lower CO2 emissions and smoke, which has major environmental consequences for South Africa.

Reducing emissions and smoke is very important for South African environment, especially with the signing of the Paris Agreement on Climate Change in 2016. The purpose of the agreement is to, ‘guide international efforts to limit greenhouse gas emissions and meet to meet all the associated the challenges posed by climate change’.

According to PwC’s SA Mine report, it is important for a mining operation to fully understand the potential of climate change to develop and integrate climate change adaptation strategies into company policies. Sancho added that the current legislation on emissions and sulphur content has resulted in a shift from 500bpm diesel to 50bpm diesel, particularly in the underground mining space.

DE also reduces the fall-off in the engine’s performance. It also has a fuel economy formula that contains an anti-rust formula, which helps to prevent rust. This anti-rust formula helps to prevent rust forming on steel components such as the injection pump. In addition, the fuel economy formula also forms a protective layer between the metal surface and the water molecules, preventing corrosion. It also has an invisible waterproof and rustproof layer that protects the fuel system.

Benefits of Dynaflex Technology and Diesel Extra

  • Better fuel economy
  • More load pulling power
  • Vehicle reliability
  • Engine acceleration and performance
  • Efficiency
  • Extra torque
  • Reduces operating costs
  • Lowers downtime

What does this mean for the mining industry?

Sancho explained Shell’s position within the South African mining industry. “I think Shell is the most significant partner and supplier in the industry with the biggest mines in the country.” This was in terms of fuels and lubricants. He adds how the fuel company has longstanding relationships with all the top four and five mines­ — including Glencore and South 32 — in terms of fuel and lubricants market share.

Ashley Abrahams, national sales manager for Commercial Fuels at Shell South Africa, explains that fuel discussions are mostly associated with passenger vehicles. “There’s an often-forgotten sector out there called the commercial sector. The sectors I’m referring to is the mining sector, transport sector as well as construction sector,” says Abrahams. He explains how these sectors each have their own unique set of requirements, meaning they need a different type of fuel to meet their requirements. “Our commercial customers will experience major benefits with our new fuel formulation,” he adds.

Dynaflex technology has two benefits to the mining industry, namely performance and efficiency. The technology contributes to engine acceleration and performance for vehicles used in the mining sector. “Designed for increased efficiency, our customers enjoy better performance, improved operating costs and maximise the return on fleet investment.”

Abrahams adds that the Dynaflex fuel technology has powerful deposit additives for both petrol and diesel that assists engines in performing better. “Our Shell Diesel Extra with Dynaflex Technology can save customers up to 3% on fuel costs,” Abrahams says. This means that customers get 3% of their fuel expenditure back into their pockets.

“We believe this has tangible value benefits to our customers.”


“This technology has got dual detergent Dynaflex technology which is applicable for both older engines and newer engines,” says Howard Nkohla, technical manager for fuels at Shell South Africa. He adds that the Dynaflex also has clean-up and keep clean technology, which is suitable in mining because of the industry’s diversity. “The newer engines are kept clean and the older ones that have carbon are cleaned up to perform better,” Nkohla adds.

According to Howard another benefit of Dynaflex fuel technology is the antifoam property for faster filling and refuelling. The property reduces the formation of fuel during the process of refuelling and results in more fuel in the tank. This property also has less spills.

To test the DE fuel economy within the mining industry, Shell conducted an experiment using two models of Caterpillar dump trucks. One was a 777D, 100-tonne payload, 32L V12 engine dump truck. The other one was a 785C, 150-tonne payload, 52L V12 engine dump truck.

The results of the experiment show that overall average fuel economy benefit for both trucks was 2.2%. The experiment was based on Shell’s DE without the inclusion of Dynaflex. If the results are anything to go by, then customers within the mining industry stand to gain more from fuel with the inclusion of Dynaflex technology.

Both Nkohla and Sancho agree that the Dynaflex technology is a good option for the mining industry. “We believe this has tangible value benefits to our customers,” comments Sancho. The launch of the fuel technology could not have come at a better time, considering the current economic situation in South Africa and globally.

“Given the commodity downturn, I think our customers look for better value offers, they look for benefits of the product and its effectiveness in relation to their spend.” It is the best product that will help mining customers to reduce their operating costs and reduce maintenance,” adds Nkohla.
