The trial recorded fuel economy every time the tank was filled, manually noting down the litres added and mileage covered. 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. 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.

Firstly, if you have an older or higher-mileage car, you are far more likely to see noticeable improvements in performance and fuel economy compared to a newer, lower-mileage vehicle. Given that fuel deposits and debris build up in your engine over time, it makes sense that you’ll notice a greater improvement in an older engine that has seen a few million more fuel explosions than a newer engine. If I’d been running the same test on an older car I am sure I would have seen some more noticeable results, but unfortunately I don’t have an older car to call upon for such a purpose (and buying an old banger to drive for three months didn’t really appeal!) If you have a modern diesel-powered car, chances are it has DPF installed. However, all DPF’s have a limited capacity to capture soot expelled from the engine. Leave the DPF unattended and you will likely suffer from poor performance, warning lights and the possibility of breakdowns and expensive engine damage. 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. Yes, Redex is good for your car. It helps to remove harmful deposits that build up in your fuel system over time, restoring lost performance, improving fuel economy, and reducing emissions. Regular use of Redex can help maintain your vehicle’s performance and keep it running smoothly. How to Clean Diesel Fuel Injectors It’s my second Dacia and will be dealer serviced whilst under warranty. Thereafter I’ll self-service it using the correct Renault/Dacia fluids. I’ve no qualms about removing the EGR every 50k or so to clean it, and hope to be able to get towards 100k or so before I need to pull the dpf for an overnight bath in Wynns DPF cleaner and a gentle up-stream power wash, before replacing it.

Do I need DPF Cleaner for a petrol engine?

Costs for this serve seem to vary but in most cases it is much cheaper than a replacement filter and not illegal like DPF removal (more on that below). In an effort to cover all bases when it comes to DPF cleaning, JLM also offer a spray solution, alongside their pour-in additive. Like the additive solution, the spray DPF cleaner offers professional level results for all customers, with a highly tested and extensively researched product. Engine light came on July ’18 – DPF burn at garage (A) didn’t work – Wurth cleaner used and successful. Glowplug also replaced at this time. So do additives and in particular DPF cleaning additives work? Yes absolutely, but they can’t perform miracles.

A passive regeneration occurs when the vehicle exhaust system has reached a particular temperature after a sustained period of driving at specific speeds. Generally, this occurs when driving on a motorway at speeds of around 50-70mph for more than 30 minutes. With diesel prices at record highs, taking your car for a longer, faster run just to clean the DPF is wasteful, inconvenient, and could cost you money. Redex System Cleaner eradicates this deposit build-up. Regular use will keep the injectors in their best working condition, and save you money when driving. Spray cleaners are administered directly into the filter via an oxygen or pressure sensor bung in the exhaust. Simply remove the existing sensor and attach the provided tube, spray into the exhaust and replace the removed sensor. It does require a couple of basic tools, possibly a way to get underneath the vehicle and a little extra time but should yield very impressive results. Using the product regularly is recommended by Redex to ensure issue free running in the long term, though the regularity may be exaggerated to ensure higher profits. It is used in this way to help prevent build-up as well as fixing existing issues. Couldn’t a Mechanic Solve the Problem?Our 3.0 Bmw X3 Diesel E83 recently started giving problems and the cause was the dreaded Dpf. I tried three different makes of additive in the fuel tank but to no avail. I also attempted a manual regen. but again to no avail. I therefore had several choices.
