All modern cars with a diesel engine have a diesel particulate filter. The filter captures incompletely combusted fuel (soot) from the engine that would otherwise end up in the environment.

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? For a diesel engine to perform optimally, to be as efficient as possible and to emit as little harmful exhaust fumes as possible, the complex fuel systems of diesel engines need to be well maintained. Preventative maintenance ensures a trouble-free service life and avoids expensive repairs to components such as EGR systems and diesel particulate filters (DPF). JLM Diesel Extreme Clean combines the advantages of all individual diesel additives and can be used in all old and new cars with a diesel particulate filter. How to use JLM Extreme Clean

Best DPF Cleaner Overview

Update ! (2016)We’ve been speaking to some industry experts on this matter and we’d like to offer an updated view. Other manufacturers add more iron to the additive to achieve the same results and advantages as JLM. The result is an increase in the amount of ash in the filter, which means that the filter must be cleaned more often and does not last as long. Update – October 2023– We have updated our product recommendations in line with some excellent new products that have been released in the UK market. Our advice would be to use a good quality DPF cleaner to keep the system clean and also to ensure your car is treated to a decent run out allowing the system to do what it needs to do. This is one of the reasons we have added to and enhanced our Best DPF Cleaner article as the needs has increased What is a DPF?

If all else fails then do be very careful how you proceed. Removing the DPF from your exhaust system has become rather a hot topic with transport regulators across the globe, if you have the DPF filterremoved you encounter issues passing your MOT or vehicle inspection. 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; 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;The DPF catches soot (carbon) and about every 2000-5000 miles the engine management system will try to remove this by burning it. This can only happen if the car is driven (different manufacturers have slightly different strategies) on a fastish road above about 40-50mph for about 20 mins. If you don’t do this then at some point the car becomes desperate for a regen and may try and get some carbon burnt at less than ideal conditions. If this does not happen then at some point there is too much carbon and it could damage the substrate if a regen was started. Using a DPF cleaning additive as a preventative measure could potentially save you thousands in repair bills. Once a diesel particulate filter is totally clogged with deposits it often has to be completely replaced. Depending on the car make and model, a new diesel particulate filter, including dismantling and fitting, can easily cost 1000 euros and in some cases up to 5000 euros. DPF filters are fitted to all modern diesel vehicles and were introduced around 2009 to comply with Euro 5 exhaust emissions rules, some vehicles were fitted with them slightly prior to this. Only Got 5 Minutes? Another contributing factor to DPF problems is poor quality diesel fuel. The more expensive, premium fuels contain additional additives which help reduce the amount of soot build up. Why Should I Use A DPF Cleaner?

It’s no wonder we are all so confused. My 2013 Transit handbook says nothing of any real use about the DPF or regen process. I wouldn’t surprised if most other vehicle handbooks were the same, i.e. bloody useless! There is no indication on my dash that a regen is taking place & I have never noticed it running any differently that might indicate a regen. It doesn’t smoke so the soot, is going somewhere (DPF) but the exhaust fumes do smell different from my old pre-DPF van. Short journeys – The engine is not so efficient during warm up, and does not get hot enough to burn off deposits Conventional cleaners contain iron to initiate the regeneration process. JLM Diesel Particulate Filter Cleaner comprises a high concentration of a patented platinum-cerium compound. The combination of platinum and cerium ensures, in the first instance, significantly improved regeneration and cleaning of the diesel particulate filter compared with conventional cleaners. The higher the concentration of platinum the better the regeneration.JLM Diesel Particulate Filter Cleaner solves this specific problem. There is no need to dismantle the diesel particulate filter. This saves time and therefore money. Add the contents of a bottle to a full tank of fuel and drive the car again. The cleaner ensures that the soot in the diesel particulate filter burns at a low speed, when the engine is under a light load and even during short journeys. I have owned a 2.0 Jtdm Alfa 159 for 3 1/2 years now and have done approx 30k miles with it. After a few months the car went into ‘regen’ with the exhaust rattling and shaking as if it was falling to pieces, then did it again a few weeks later. I then did a bit of forum research and decided to try the Wynns DPF cleaner, after a good run (about 20 miles ) and a higher revs blast there was some dark smoke then some lighter coloured grey smoke blown out and after that I’ve not had another ‘regen’ incident. JLM Diesel Particulate Filter Cleaner is a durable solution for the effective and targeted cleaning and preventive cleaning of the entire exhaust path of diesel engines with a particulate filter (DPF). JLM Diesel Particulate Filter Cleaner not only cleans the soot filter, but also reduces air-polluting particulate matter hydrocarbons (HC), carbon monoxide (CO) and soot emissions. For this reason, JLM Diesel Particulate Filter Cleaner can mean the difference between APK approval or rejection. JLM Diesel Particulate Filter Cleaner reduces soot and fine dust emissions by up to 25 percent. This means that less soot gets into the soot filter, which reduces the chance of clogging and increases the service life of the filter. If your diesel car is fitted with a DPF, it’s imperative that you use DPF compliant engine oil. Using an oil that doesn’t meet the required specifications for your engine can result in catostrophic failure.
