Trusted by professionals and backed by a decade of success, it’s the ultimate solution to keep your diesel engine running at peak efficiency. ## Description Note: The two products CANNOT be mixed. Use the AR6400-D Max first and then use the AR6900-D Max on the next fill up. This listing is for: 1 x Archoil AR6400-D MAX Pro Diesel Engine, Turbo, DPF Cleaner Concentrate - 400ml 1 x Archoil AR6900-D Max Advanced Fuel Synthesis - 250ml A rapid improvement in engine technology has resulted in an imbalance between engine design and fuel quality. This combined with non-optimum driving conditions can result in an accumulation of deposits in the fuel system, combustion area, turbo, diesel particulate filter (DPF) and catalytic converter (CAT). These deposits effect performance, fuel economy, exhaust emissions and engine refinement. They can also cause engine warning lights or restrictive β€œlimp home” conditions. To address these issues Archoil has released its latest high-strength diesel cleaner, AR6400-D MAX. AR6400-D MAX is a powerful next-generation all-in-one fuel system, engine, turbo, DPF and CAT cleaner. It is the culmination of years of research and the decision to combine the original AR6400-D Engine Cleaner, AR6500 DPF Cleaner and AR6600 Turbo Cleaner technologies providing the greatest value and product performance into a single treatment. FUEL SYSTEM CLEANER AR6400-D MAX quickly restores engine performance and fuel economy lost through deposit build-up in key parts of the fuel system, engine and emission control systems. Molecule by molecule deposits are safely removed. AR6400-D Max helps restore variable geometry turbo operation and diesel particulate filter regeneration. AR6900-D MAX will remove all forms of deposits from fuel injectors including carbons, varnish and stubborn lacquers. AR6400-D MAX will effectively clean older as well as modern Euro 5/6 specification fuel systems. It is suitable for all diesel engines running on pump, bunkered or bio-diesel blended fuel. LUBRICANT AR6400-D MAX delivers a modern lubricant helping to protect high pressure injection systems and fuel pumps during the cleaning process. CETANE BOOSTER & COMBUSTION CATALYST AR6400-D MAX contains a proven cetane booster to improve combustion efficiency and engine performance, whilst reducing engine noise. A combustion catalyst technology then facilitates a cleaner burn, improving combustion quality further. These additional functions not only provide an instant improvement in performance but facilitate the cleaning function by keeping recirculating hydrocarbons as low as possible. FEATURES/BENEFITS: Rapidly Cleans Fuel System & Combustion Area Removes Deposits from Turbo, DPF & CAT Raises Cetane Index Number Smooths Rough Idling Lowers Harmful Exhaust Emissions Lubricates & Protects the Fuel System Restores Lost Performance & Economy USAGE INSTRUCTIONS Add the correct amount of AR6400-D Max to the fuel tank first and then fill up with fuel immediately afterwards. Treatment ratio is 1:100 > 1:200. A single 400ml bottle will treat between 40 and 80 litres of fuel. A 5 litre container will treat up to 1000 litres of fuel. CAUTION: Do not overdose. Use every 5000 miles or use once and follow up regularly with Archoil AR6900-D Max Review: Worth To Try - It's a really good product. It's really working on my VW Tiguan 2015 2.0 TDI diesel engine ,117600 miles driven. I put the whole bottle in 20 litre fuel left and immediately full tank. Review: WOW..well this definitely worked!! - Ok so im not realy one to believe in snake oil hypes etc..however i think i should share this with you people out there..(perhaps to a few sceptics too..) So i had just purchased a Nissan xtrail 2.0 dci..& on the way home management light came on..(perhaps the crook trader deleted it prior!)..so off it went to my local mech & it came up with a brake switch fault/failure but it was a dealer part only.. Now i personally thought it could be the DPF as it had been stood a month or two prior to my purchase..(common issue with the xtrails of that year) & there were some tell tale signs that it may have had some neglet in regards to normal servicing.. So I trawled the net for a good DPF cleaner & this 'Archoil' popped up..so i read the reviews etc what it did for people's cars, how it improved functionality of their cars, turbo spool improved etc.. I was feeling flush that day so i thought let me waste Β£20..not a cheap product but i had planned a trip to Devon the following week (6hr drive) so i bought it.. Threw it all in with a full tank of 'normal' diesel, not V Power (yet)..& 310 miles later management light still lit & the car felt sluggish on acceleration as it did when i purchased it.. Drove it around there over the week & filled tank up again for the journey back. Just as if by magic at the fuel station the management light went..it LITERALLY went by its own accord!! Ok wow Brilliant..now lets see it on the motorway.. Hit the motorway & no word of a lie..the 4x4 felt ALIVE! Turbo spooled well, i got the acceleration i wanted, the overtaking was safe & comfortable..so whatever this ARCHOIL is..WORKED FOR ME!! Now whatever it did for the car, cleaned the DPF, or turbo, or exhaust, or whatever..im GLAD i bought it! 5 stars from me..(for a change! Lol!) ## Features - FAST, SAFE AND THOROUGH CLEANING.
