Used for all grades of Diesel fuel and heating oil to secure winter operation which would otherwise be affected by the cold in passenger and Diesel engines, construction machinery and stationary Diesel engines.
For optimum effect in preventing paraffin separation, it is necessary to add the flow improver approx. 5 A°C before the cloud point (turbidity point) is reached. To improve mixing, add Diesel Flow Fit before filling up with fuel.
Item Package Weight: 0.16 kg
Item Package Dimension: 5.5cm L x 9.0cm W x 12.0cm H
How to choose a good diesel fuel additives for winter?
On the surface, choosing a diesel fuel additives for winter seems simple. But once you dig in, it gets more complicated. Between technical differences, unfamiliar brands, and unclear features, it’s better to ask the right questions:
Usage: Will you use it daily or only occasionally? That heavily influences the right model.
Budget: No need to go for the most expensive one right away. What matters is the value for money.
Key factors:
Durability, build quality, lifespan
Truly useful features (not just marketing buzz)
User reviews, especially after weeks or months
Availability of customer service in case of issues
We’ve cross-checked multiple sources: Amazon data, detailed reviews, search trends… and a bit of intuition too—because numbers don’t tell the whole story. This mix allows us to build our ranking, which we update regularly. The goal isn’t to just list names but to guide you toward what truly works.

✅ CLEANS THE ENTIRE DIESEL FUEL SYSTEM: Effectively removes dirt, carbon deposits, and other harmful residues that accumulate within the fuel system over time. Ensures a cleaner and more efficient combustion process by thoroughly cleaning key components such as the fuel pump, diesel injectors, and intake valves. By dissolving stubborn contaminants, it helps prevent clogging and improves the overall efficiency of the fuel delivery system. Designed to work in a single treatment, providing a powerful 'one tank' clean-up that restores optimal fuel system functionality.
✅ RESTORES FUEL ECONOMY: This product helps optimise fuel consumption by ensuring a cleaner and more efficient fuel-burning process. By eliminating harmful deposits and improving fuel atomisation, it contributes to a smoother and more complete combustion cycle. This results in less fuel waste and improved miles per gallon, allowing for greater cost savings over time. By restoring lost performance, the cleaner enables engines to operate at peak efficiency, reducing unnecessary fuel consumption caused by inefficient combustion. Ideal for vehicles experiencing a decline in fuel economy due to carbon build-up and fuel injector blockages.
✅ PREVENTS PROBLEMS WITH TURBO, EGR VALVE & DPF: Designed to maintain the cleanliness of crucial engine components such as the turbocharger, Exhaust Gas Recirculation (EGR) valve, and Diesel Particulate Filter (DPF). Helps prevent carbon and soot build-up, which can lead to blockages and reduced performance. By keeping these components clean, it enhances engine efficiency and reduces the risk of costly repairs. Supports proper airflow and exhaust circulation, ensuring smooth turbo operation and reducing emissions. Helps to minimise common diesel engine issues such as sluggish acceleration, excessive smoke, and reduced power caused by carbon deposits.
✅ ELIMINATES AND AVOIDS STARTING PROBLEMS: Effectively addresses hard starting issues caused by contaminated fuel or clogged injectors. Ensures a smoother ignition process by restoring proper fuel flow and combustion efficiency. Helps eliminate rough idling, misfires, and hesitation that often result from a dirty fuel system. By cleaning the fuel injectors and fuel pump, it improves cold starts and reduces strain on the battery and starter motor. Ideal for vehicles that experience difficulties starting due to carbon deposits and injector blockages.
