It’s also a really easy to use product, just putting a single bottle of Redex cleaner in to the tank at each full-up, which soon becomes second nature. What have we found in the last few months of using Redex?
The warning light is there to serve as an alert that the system requires attention. It’s really important to take action as soon as the light illuminates, failure to do so can result in an expensive repair bill. DPF’s have been fitted to comply with European emissions regulations and it is illegal to alter or remove the system. Wynn’s, the US based company, have developed an outstanding reputation over many years. They produce a whole host of engine performance additives and this DPF cleaner scores highly for value for money. Impressively, this DPF cleaner is also suitable for use in biodiesel vehicles all the way up to B30. The key features of Wynn’s DPF cleaner are;
Features and Benefits
The EGR valve (Exhaust Gas Recirculation Valve), sits in the engine bay and exhaust gasses flow through it before moving on through the DPF filter. Because diesel fuel is quite oily in it’s formulation, diesel cars often suffer from carbon build up in the engine. An EGR valve is a prime candidate for coking up with carbon and often results in reduced gas flow through the valve. Again, a common cause for EGR valve problems is frequent short journeys around town as opposed to motorway journeys. Part of Liqui Moly’s Pro Line of products, the German branded Liqui Moly DPF cleaner takes our top spot. Liqui Moly claim it’ll dissolve hardened, dense and encrusted contaminants on the surface of diesel particulate filters ensuring optimum performance at all times. As well as restoring performance of the engine, crucially, it’ll also improve fuel consumption significantly. Liqui Moly have built up an excellent reputation for producing exemplary car care products and this DPF cleaner is arguably one of their most impressive products yet. The key features of Liqui Moly Pro Line DPF cleaner are; Prior to the conception of DPF filters, those harmful exhaust gasses were being pumped straight out into the atmosphere.
The product lowers the temperature at which soot burns in the engine, meaning fewer harmful particles reach the DPF, and the filter stays clearer for longer. If you want to maintain your car’s engine and ensure the DPF warning light never comes on, we’d recommend adding a shot of Redex DPF Cleaner to your car with every 2-3 tanks of fuel. Just insert the nozzle into the fuel filler cap and pour – it’s as easy as that. SparkRight claimed this device would give you ‘up to’ a 20% fuel saving! I wandered around the shop, and realised that with Platinum tipped spark plugs giving ‘up to’ 10% GTX up to 10% Redex, plus a few more, if all of them worked I’d be using no petrol at all!
Redex DPF Cleaner works to clear soot from your car’s particulate filter, reducing the likelihood of a fault and switching off the warning light. Easy and convenient to use, it means you don’t have to take your car for a trip on the motorway to burn off soot from inside the DPF. Modern diesel engines currently produce less carbon dioxide levels than petrol engines, however they produce much higer NOx levels. High levels of NOx are dangerous to the environment and can cause respiratory problems for humans such as inflammation of the airways. It’s for these reasons that systems such as DPF filters were introduced. How Does A Diesel Particulate Filter Work? A close runner up, Cataclean 6160 DPF cleaner offers exceptional performance at a really impressive price point. Cataclean claim it’ll reduce emissions but as much as 60%, a really impressive bit of kit. As well as protecting and cleaning the DPF, it’ll also protect and maintain catalytic converter systems. The key features of Cataclean 6160 DPF cleaner are; You can avoid this hassle by using Redex DPF Cleaner, which helps to keep the filter clean without other preventative measures. Where to Buy Once the exhaust has reached the specific temperature, the vehicle will begin the regeneration process which consists of the soot inside the filter canister being burnt off to create more space inside the filter.
Update – November 2022– Interestingly, modern petrol or gasoline vehicles are now being fitted with DPF equivalent type filters. Gone are the days or buying a petrol vehicle to avoid frustrations with exhaust filter systems. Motoring product specialists such as Liqui Moly, Wynn’s and Cataclean are now producing DPF like cleaning products for petrol and gasoline cars. It’ll be interesting to observe whether PPF’s prove to be as problematic as DPF’s have been for modern Diesel engines. Redex DPF Cleaner is a specialist fuel additive that helps to keep particulate filters in diesel engines clean. We had no hesitation in trying this out, especially as just about everyone at Cars UK Towers has used Redex at one time or another, and were confident it was safe to use. Like all Redex fuel additives, our DPF Cleaner can be added to a full or partially full fuel tank as and when required. It’s also safe to use with other products in the Redex diesel fuel additives range. How do I use DPF Cleaner?As well as testing multiple cleaners, we also based our recommendations upon the latest research and a number of factors. Some of the factors that we took into consideration included how easy they are to use, duration between the treatments, additional qualities and value for the money. Conclusion You can also use the DPF cleaner in conjuction with cheaper diesel as opposed to using more premium diesel fuels at each fill up. Should I Use A DPF cleaner If My Warning Light Is Not On? Alternatively, you can add a shot of DPF Cleaner when the light comes on. Add a dose to your car’s fuel tank, drive as normal, and you should find that the light switches off without the need for that inconvenient trip to the motorway. Do I need DPF Cleaner for a petrol engine?
