Compatible with all diesel engines, including vehicles fitted with anti-misfuel filler neck protectors. - DPF and EGR Cleaning: Helps clean DPF deposits and restore exhaust flow; frees problematic EGR valves clogged with carbon buildup; rapidly reduces harmful exhaust emissions and unwanted black smoke from the exhaust. Regular use helps prevent future carbon accumulation in the DPF and exhaust system. Designed to help lower emissions ahead of MOT testing, making it a practical choice for pre-test diesel maintenance and ongoing vehicle care. - Restores Engine Performance: Directly addresses rough idle, hesitation, power loss, and sluggish throttle response caused by carbon deposit buildup in the fuel system. Effective on high-mileage diesel engines where years of accumulated deposits have degraded performance. Helps restore lost fuel economy by cleaning fuel injectors and combustion chamber. Also cleans turbo carbon deposits to help recover boost response. Works as you drive with no tools required. - Advanced Proprietary Formulation: Fuel System Detergent, Carbon Cleaner, Nano Fuel Borne Catalyst, 2-EHN Cetane Improver, and Ester Lubricant. Includes the highest purity 2-EHN cetane improver for smoother cold starts and reduced combustion noise. Ester lubricant protects fuel pump and injectors against wear. - Simple to Use: Pour directly into the fuel tank before refuelling. Works as you drive with no tools or mechanical knowledge required. Add to fuel tank as part of regular diesel maintenance to keep DPF, EGR, and fuel system clean over time. Includes a secure pour spout designed to fit standard diesel filler necks, including anti-misfuel protectors. Professional-grade formulation developed and manufactured in the UK. Trusted by professional mechanics and fleet operators for over a decade. ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B00KQ1ALKC | | Best Sellers Rank | 768 in Automotive (See Top 100 in Automotive) 23 in Fuel Systems | | Brand | Archoil | | Customer Reviews | 4.5 4.5 out of 5 stars (1,691) 4.5 out of 5 stars | | Date First Available | 2 April 2021 | | Delivery Information | We cannot deliver certain products outside mainland UK ( Details).

If you mean just while in traffic, yes as long as the engine is running. **Q: when do you put it in?empty tank or anytime** A: It states to wait until tank is nearly empty then add immediately (ie at Petrol station and without starting the engine) before filling with approx 40-80 litres of diesel per full 430ml of additive. I used half in 40 litres **Q: Is it recommended for EGR cleaning ?** A: Not sure if it cleans EGR But works incredibly great for turbo,DPF,and cat , best on market does what it says **Q: How often can it be used as i do 600 mile a week and first one made a difference** A: It takes probably around 10 to 20 thousand miles for the carbon to build up in places like the EGR (exhaust gas recirculation valve ) if yours has never had this treatment you will have possibly noticed a difference before and after? Hope that’s a help ## Customer Reviews ### ⭐⭐⭐⭐⭐ From Sluggish to Sensational: Archoil AR6400-D Resurrects My BMW 520d *by on Reviewed in the United Kingdom 13 June 2025* A single 400ml bottle of Archoil's AR6400-D MAX Pro has completely transformed my BMW 520d, resolving a host of frustrating issues and saving me from what I feared would be a costly visit to a specialist. For any owner of BMW's otherwise brilliant diesel engines, this high-strength fuel system cleaner is an absolute must-try.My 520d, a car I rely on for its blend of performance and economy, had started to feel tired and unhealthy. The once-sharp acceleration had become noticeably sluggish, there was a definite hesitation when pulling away, and I’d spotted the dreaded puff of smoke from the exhaust when accelerating hard. With an upcoming MOT, the potential for DPF and emissions-related problems was a major worry.These symptoms are unfortunately common for many modern diesel cars, including the venerable BMW 520d. Carbon build-up across the fuel system, clogged injectors, and a struggling DPF and EGR system, often worsened by urban driving cycles, can strangle the engine's performance and efficiency.Having seen positive reports about Archoil AR6400-D, I opted to try it before committing to expensive diagnostic and repair work. I added the full bottle to a tank of premium diesel and made sure to give the car a good, long run on the motorway to let the powerful cleaning agents circulate properly.The difference is, frankly, night and day. The most immediate improvement was the restoration of the car's responsiveness. That annoying lag has vanished, and the engine now delivers the smooth, eager performance I expect from a BMW. It feels sharper, stronger, and pulls cleanly through the entire rev range.Crucially, the tell-tale smoke from the exhaust is gone. This gives me huge confidence for the impending MOT, as it's a clear visual sign that the AR6400-D has done its job of clearing out soot and carbon deposits from the engine and exhaust system.The entire driving experience has been elevated. The engine runs more quietly and feels significantly smoother, both at idle and on the move. It's as if the Archoil has performed a comprehensive internal detox, allowing the injectors, turbo, and DPF to function as they were designed to.For any BMW 520d owner experiencing a decline in performance, rough running, or facing anxiety over DPF and emissions warnings, I cannot recommend the Archoil AR6400-D MAX Pro enthusiastically enough. It has proven to be a remarkably simple and cost-effective solution that has genuinely resolved all the running issues my car had developed. Consider it an essential part of your annual maintenance schedule to keep your BMW performing at its peak. ### ⭐⭐⭐⭐⭐ Brings the pep back *by on Reviewed in the United Kingdom 23 July 2026* Skoda Yeti 2.0 TDI CR170, 84,000 miles. Felt a bit sluggish, and was recommended this.Added a 400ml to a 50 litre fill-up of basic Supermarket diesel, (the AR6400-D already has all the additives the premium has) and took it out for a 40 mile ‘spirited drive’.Everything now runs quieter, she revs easier, the sluggishness has disappeared, the turbo kicks-in earlier and much stronger, the fuel economy has improved, and the performance now matches the claimed figures.If your DPF is completely ‘bunged-up’ then this isn’t a miracle cure, (you’re going to have to bite the bullet and have it removed for a deep clean) but regular use will stop it getting that bad.Will be using every 5000 miles from now on, and running AR6900-D in every other tankful. ### ⭐⭐⭐⭐ A real performance Improvement. *by on Reviewed in the United Kingdom 21 January 2015* I've been told (by clever friends) that this stuff is very good. I have a 130,000 miles BMW 635d and I did feel it wasn't as fast as it used to be and I have recently had a few DPF warning lights. For less than £20, I thought it was worth the risk and I have to say my car now DOES feel a lot faster than it did. Smoother, more urgent and I suddenly remember why I bought the car in the first place.Another issue I had was 'squeeling' from one of the turbos, especially when cold (I assume bearings on their way out). Well that's stopped now. I assume grime has been removed from some of the moving parts.I'm only giving 4 stars for now because I've only done 500 miles since adding AR6400. I want to run it for a few 'normal' tanks full to ensure the performance stays and the warning lights stay off. I'll report back in a month and give the extra star if the warning lights stay away and the horses are kept in. ## Frequently Bought Together - Archoil AR6400-D MAX Pro DPF Cleaner Diesel Fuel System, Diesel Injector Cleaner, Turbo, CAT Cleaner Concentrate - High Strength Carbon Removal & Exhaust Emissions Reduction for MOT Pass (400ml) - Archoil AR6900-D Max Advanced Diesel Additive Concentrate, 1L Treats 1,000L of Fuel, Diesel Fuel Injector Cleaner, DPF Filter EGR Valve Turbo Cleaner, Super Diesel Converter.
