Suitable for all diesel engines including Euro 6, it enhances fuel economy, protects critical components like DPF and turbochargers, and is fully compliant with UK and EU standards. Trusted by professionals and backed by a decade of proven results, it’s the ultimate fuel system performance enhancer for modern diesel vehicles. ## Description Product Description ARCHOIL AR6900-D MAX AR6900-D MAX is an advanced fuel conditioner that is specifically designed to address inherent deficiencies in modern diesel fuels. AR6900-D MAX essentially converts regular diesel into Super Diesel. It enhances regular BS EN 590 pump fuel but is also performant in all other diesel fuel types including bio-diesel. AR6900-D MAX has been engineered to clean, lubricate and protect the fuel system whilst enhancing combustion performance through the use of a cetane improver and Archoil’s combustion catalyst technology. AR6900-D MAX is suitable for diesel car, van, bus, truck, agricultural and marine including the latest Euro 6 classification or those with the latest high pressure common-rail injection fuel systems. AR6900-D MAX can reduce fuel usage, exhaust emissions and carbonaceous deposits, which help protect the catalytic converter, turbo charger and diesel particulate filter (DPF). Meets the latest DW-10 performance test Lowers carbon & reduces DPF regeneration cycles Protects against corrosion & water emulsion 100% safe & active ingredients Fully BS EN-590 compliant No Harms tested Optimised for & tested on EN 590 pump fuel Features / Benefits Converts regular diesel into Super diesel Restores torque, horsepower & fuel economy Reduces harmful exhaust emissions Prevents sludge & surface build-up Dispersant - removes existing solids in the fuel Lubricant - lubricates the fuel system & upper engine Detergent - safely cleans injectors & removes deposits Stabilizer – extends the usable life of fuel FUEL SYSTEM CLEANER AR6900-D MAX contains the latest technology in detergent performance, extensively tested to provide controlled removal of deposits and keep fuels systems, injectors and engines clean. AR6900-D MAX will remove all types of deposits from the injectors including carbons, varnish and stubborn lacquers. AR6900-D MAX will effectively clean older as well as modern Euro 5/6 specification fuel systems. This results in restored engine performance, MPG and reduction in harmful exhaust emissions. LUBRICANT AR6900-D MAX delivers a modern ester-based lubricant helping to protect high pressure injection systems and fuel pumps from today’s low lubricity, low Sulphur (USLD) fuels. Energy produced by the combustion process can be lost due to internal friction in the engine between the piston rings and cylinder walls. AR6900-D MAX lubricates these areas resulting in improved engine performance and protection, making it the perfect additive for poorly-additized bio-diesel blended fuels. STABILISER, DISPERSANT, CORROSION INHIBITOR & WATER DEMUSLIFIER AR6900-D MAX contains antioxidants designed to stabilise and extend the life of fuel in storage. An integrated corrosion inhibitor protect fuel tanks and key fuel system components from oxidation. AR6900-D MAX prevents water emulsion and keeps water out of the fuel. Foaming is also reduced. CETANE BOOSTER & COMBUSTION CATALYST AR6900-D MAX contains pure 2-EHN cetane improver (up to 5 points) to improve combustion efficiency and engine performance, whilst reducing engine noise. A combustion catalyst technology then facilitates a cleaner burn, improving combustion quality further thus helping to improve performance whilst reducing fuel consumption, exhaust emissions and deposit build-up in the combustion area, turbo charger, DPF and catalytic converter. Continuous use will reduce combustion, turbo and DPF deposits reducing the need for other dedicated cleaners or DPF regeneration cycling. Review: It actually does a fantastic job - 7 month use! - I've yet to see the cleaning power as i'm not testing it and comparing before and after in my diesel car but the improved starting capacity has been noticed as I used about 30ml whilst on about 35 ltrs of diesel in a 50ltr tank. I will check my egr in a week or two to see how much it's helped keep that clean as I disconnected my egr to partially clean it whilst in place just before using this product. For the price you get more than one use worth, you get quite a few so this is a product to last over a year depending so for maintaining the fuel and helping the system it's well worth the money. I'm already seeing an improvement to my average MPG which while pottering about town doing short trips is very beneficial. EDIT: After 7 months of use doing a lot of short journeys I can say without a doubt this is a perfect product for keeping a diesel in optimal health as my system runs better, it's cleaner and i'm never having issues with starting, my average mpg has risen to 31mpg which is a huge improvement over the 22mpg I was seeing before I started using it, and if i go on a longer journey it continues to rise until im back to my working day routine doing short trips, and if i take my car out on the NSL roads i'm seeing upwards of 36mpg - did i mention that cold starts aren't an issue anymore? The engine runs so much better with this product in it with the correct amount ie 1:1000 ratio so 1 ltr=1ml, for my 53 ltr tank i need two squirts of this bad boy as they are about 25ml each. I swear by this product as i've had concerns about my dpf and egr getting clogged and being at risk due to my driving habits and after having my egr out twice over the last 7 months to inspect it i can confirm this product is actively cleaning the system, it's not making the egr spotless but the buildup of carbon has been drastically reduced and the EGR is less like a carbon-geode cracked open, even my egr valve solenoid is relatively clean. I'll be forever buying this and adding 70ml to every tank before i top up with new fuel, it's a incredibly affordable product that works like a charm! Please do wear gloves when handling the bottle as while it's not the worst smell in the world you don't want it getting on your hands and then on the interior of your car where you will smell it for weeks. Review: Amazing product. - Was reccomended to try this by a mechanic, after I had a service done. I've always used Redex once a month, to keep fuel system clean, and always achieved 60-65mpg. Using Archoil in every tank now for the past month, and I'm achieving amazing results on my daily urban commute. Engine responds better and the mpg is unheard of before, for a 2ltr Passat diesel estate with 119,000 miles on the clock. ## Features - Harmful if inhaled. - Harmful if swallowed. - Harmful in contact with skin. - Repeated exposure may cause skin dryness or cracking. - Risk of explosion if heated under confinement - Toxic to aquatic life with long lasting effects. - AR6900-D MAX converts low-quality supermarket diesel into high-performing Super Diesel Fuel using a carefully selected blend of pure 2-EHN cetane improver, multiple detergents, ester lubricant, stabiliser and combustion catalyst. - Suitable for all diesel engines and delivers ongoing Fuel System, Fuel Injector, DPF, EGR, CAT, Turbo and Exhaust cleaning. - Maintain engine performance and fuel economy.

For example, a 60L tank would require 60ml. **Q: can anyone tell me the mpg increase they got using this if any ?** A: I have been using this now for 8 years. My MPG has increased from 23 to 28 with a 1996 Fiat 2.5 in a 3,400 kg motorhome. That is equivalent to about 20% improvement one free gallon for every five. The first couple of doses saves the price of the complete bottle. You are effectively paid to use it. Performance is also enhanced with down gearchanges nearer the top of hills or not at all. Fuel consumption is calculated on full-tank to empty-tank miles. I can achieve 50MPH by the time I reach the end of a motorway downhill slip-way where before it would be about 40. If you're sceptical, try it - I was but I'm glad I overcame that. I've just ordered another bottle. I've just bought a Fiat Doblo 1.9 diesel - I'll try it in that next. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It actually does a fantastic job - 7 month use! *by D***L on 6 April 2025* I've yet to see the cleaning power as i'm not testing it and comparing before and after in my diesel car but the improved starting capacity has been noticed as I used about 30ml whilst on about 35 ltrs of diesel in a 50ltr tank.

And yes I guess I would compare I to putting premium diesel in , but then are you really saving much money in adding it yourself. I would have to do the math, but suspect there wouldn't be alot in it with the price of fuel in the UK. But long story short , seems good πŸ‘ --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.lk/products/50719139-archoil-ar6900-d-max-advanced-diesel-additive-concentrate-500ml](https://www.desertcart.lk/products/50719139-archoil-ar6900-d-max-advanced-diesel-additive-concentrate-500ml) --- *Product available on Desertcart Sri Lanka* *Store origin: LK* *Last updated: 2026-08-10*
