Review: From Sluggish to Sensational: Archoil AR6400-D Resurrects My BMW 520d - 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.
Review: Great product - real results - 2010 Volvo D5 engine with 185k on the clock, missed the last 2 services. Upon buying the car it felt like it had no boost. Put a full can of Archoil in with half a tank of BP Ultimate diesel (yes you can do this, just read the instructions). After half a tank of running this through with a 100 mile trip and I could feel the turbo kicking in. Once the tank was empty I repeated the process, another half tank with a full can of Archoil and another 100+ miles of varied driving and the car pulls great in every gear now. Very impressed.

## Questions & Answers

**Q: Will it work with car being stationery**
A: Yes but i wouldn't burn a whole tank of fuel stationary. 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

### ⭐⭐⭐⭐ Does actually work and improve engine feel and fuel economy
*by I***A on 6 May 2017*

Must admit I was sceptical that any fuel additive did anything other than waste money. However, my old diesel engine was starting to idle heavily so I decided to give an additive a try. Research on the web suggested Archoil was one of the better ones. This size of bottle is sufficient for one tank of fuel. Run your tank low and take the Archoil bottle with you to the station. Break the foil seal on the bottle and tip the bottle into the fuel tank. The long thin neck on the bottle means it goes down the fuel inlet with no splashing of the contents. Then fill up with Diesel, this will give the correct concentration of additive for a typical family sized car. I used to get around 600 miles per tank, used plus remaining miles always hovered around a total of 600 figure, now it is around 680 miles. But the biggest improvement is in engine idling, the engine is much quieter now. I do not experience any improvement in acceleration so I am still sceptical about the claims for improved performance but miles per gallon and a smoother idling are definitely improved for my 2 litre TDI engine.
