I have been adding this additive roughly every 1500 to 2000 miles for more than 3 years now and can’t praise the product highly enough and feel that I have proved that it ‘works’. Recommended. 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. Redex DPF Cleaner is a specialist fuel additive that helps to keep particulate filters in diesel engines clean. DPF’s have been fitted to comply with European emissions regulations and it is illegal to alter or remove the system. As I had to go to the trouble of removing the Dpf why not try cleaning it myself and this is what I decided to do. I figured that if I was not successful I could still take it to a specialist cleaner.
We’ve been using Redex Diesel System Cleaner in our 100k mile Ford C-Max for a few months to see if it improves performance and economy. Does it work? Wynn’s is a company that customers have come to expect good things from. The US brand has been in operation for over 80 years and continues to amass huge sales across the globe, thanks to their time-proven, effective product lines. Wynn’s have always specialised in easily applied vehicle additives that really work, something they claim passes right down to their basic consumer products, such as their DPF cleaning additive. Thankfully, now we’re finished, we no longer have a hung jury, with all three saying the C-Max is now noticeably smoother, especially when it, or the weather, is cold. Regular use of Redex fuel additives can help prevent future engine damage and improve engine longevity.

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; It is recommended to add Redex to your fuel tank after filling up with fuel. This ensures that the cleaner will mix thoroughly with the fuel as you drive. However, if you forget and add it before filling up, it will still mix with the fuel as you fill the tank. How Much Redex to Use
But the one question we’ve had from a number of readers since we first started using it is: Can using Redex damage my car?
Until 2030, there will be a place on our roads for diesel cars. If you're travelling long distances on motorways, the fuel efficiency of a diesel engine is almost unbeatable. Diesel may not be popular, but it is important. The initial baseline figure of 30mpg is pretty indicative of my usual fuel economy result, although usually that’s relying on the car’s trip computer reading rather than direct measurement. Redex Lead Replacement maintains good engine performance by stopping valve seat recession, so it protects the fragile components within classic engines. It’s also safe to use other Redex products, such as our Petrol System Cleaner, in a classic car, and this help will keep it in the very best condition, removing harmful deposits to help improve engine life. Yes, absolutely. The principle behind a DPF cleaner is to act as a preventative measure to help prevent major problems manifesting themselves accompanied an expensive repair bill. Using a DPF cleaner will cause no harm and even if your DPF is only very lighly full, the cleaner will improve fuel economy and engine performance. Can I Have My DPF Removed?
No. If your car has a DPF, you are not allowed to remove it. Taking it out will mean that you fail your MOT. Chris Williams has chosen the BMW 530d and the Ford Ranger Raptor, an ideal two-car garage for doing nearly anything. The 2 x Liqui Moly Diesel Particulate Filter Protector DPF Cleaner Regenerator 250ml is a highly effective additive designed to reduce the build-up of particulates in diesel vehicles, ultimately increasing the service life of the diesel particle filter. This product is suitable for diesel vehicles with diesel particle filters that have not been equipped with an electronically controlled additive tank system for filter regeneration, such as those found in Citroen and Peugeot vehicles. 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?Because DPF filters have limited size and capacity, they can only store a limited amount of exhaust soot. Once the system has reached it’s capacity threshold (usually around 80%), the vehicle will attempt to begin a process called “Regeneration” What Is A DPF Regeneration? Use of incorrect engine oil – always ensure you use the correct low SAPS oil specified for the engine at oil change and when topping up
Given that your engine creates dozens of explosions every single second, there’s a lot of combustion going on under your bonnet. With any burning of fuel, there will be deposits and debris that forms. Sometimes it’s obvious, like the ash that forms when you burn a log in a fireplace. Other times, like in your car’s engine, these deposits are microscopic, but the principle is the same. Over time, these deposits build up and affect your ability to keep burning the fuel properly.I mentioned in my last report that I’d previously noticed a slight cough or misfire from the Mazda on a couple of occasionsprior to using the Redex products, but hadn’t noticed anything since using the fuel system cleaners. I can report that the engine has still been running cleanly over the last six weeks, so the stuff appears to be doing its job in that respect. Summary Redex doesn’t stop at petrol and diesel cars. The system cleaner is also available for hybrid vehicles, which burn similarly to petrol engines in terms of injector build-up. Additionally, Redex offers a range of other products, from Adblue, which helps reduce diesel car emissions by up to 80%, to Lead Replacement. The latter means you can use unleaded petrol in leaded cars, especially classic vehicles, so the engine receives the additives it needs. Using unleaded petrol in a leaded engine can inevitably lead to major problems – Redex eliminates that threat. Overall, we haven’t noticed any extreme changes using Redex over the past few months. However the idea of a system clean is still a good one, though. Redex provides preventative measures for keeping fuel tanks clean and can improve fuel economy over time. We really like the idea of using a cleaner regularly as a way of maintaining the vehicle. After all, we like to keep the bodywork clean and polished – why not the engine too?
