The Diesel Particulate Filter (DPF) is a crucial component in modern diesel cars. Its function is to reduce emissions of harmful particles into the atmosphere; in other words, its role is to help preserve the quality of the air we breathe. However, the DPF can become clogged over time, affecting engine performance and exhaust system efficiency. Traffic conditions such as traffic jams or city driving can also aggravate filter clogging.

Fortunately, there are solutions such as Wynn’s DPF Cleaner, which can effectively clean the particulate filter without the need for costly dismantling. In this blog, we’ll explain how to clean your car’s particulate filter using Wynn’s additive.

Step 1: Identify the signs of a clogged particulate filter

Before cleaning, it’s essential to recognise the signs that your particulate filter is clogged. Common symptoms include a loss of engine power, increased fuel consumption, black smoke emissions and a warning light on the dashboard. If you notice these signs, it’s likely that your DPF needs cleaning.

Step 2: Get a Wynn’s DPF cleaner

Wynn’s additive is specially designed to clean the clogged particulate filter. Before starting the cleaning process, make sure you get the right Wynn’s product for your vehicle.

Step 3: Refuelling

The first step in cleaning the DPF with Wynn’s treatment is to fill up the fuel tank. Then, add the Wynn’s additive to the fuel tank. It is essential to respect the recommended quantities (for the whole bottle) to obtain the best results.


Step 4: Drive your car

Once you have added Wynn’s additive to the fuel tank, drive your car for a sufficiently long distance to allow the additive to mix effectively with the fuel and circulate throughout the exhaust system. Prolonged driving at constant speed on motorways is often recommended to promote an even distribution of the additive. The treatment is considered complete when the vehicle has consumed all the fuel to which you have added the additive.

Step 5: Repeat if necessary

Sometimes, a single treatment with Wynn’s additive may not be enough to eliminate the deposits accumulated in the DPF. If symptoms persist after the first treatment, you can repeat the process to optimise results.

Regular cleaning of your car’s particulate filter is essential to maintain low emissions and optimum engine performance. Using Wynn’s additive offers a practical and affordable solution for removing the soot built up in the DPF without needing costly repairs. By following the simple steps outlined in this blog, you can help extend the life of your particulate filter and protect the environment by reducing harmful emissions.
