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 “limp 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: Clogging gone - Good product for good price . Amazing car going to be running fast without any clogging. Review: Worked straight away ! - Amazing product, I have a 16 year old X5 that started to clog up the EGR and get sticky EGR errors. When you get any errors on how the car breaths it will block DPF regenerations, so I also had a blocked DPF; so after clearing codes and dosing my tank of fuel with this - I set off for a drive and saw the DPF successfully regenerate 20 minutes into the drive. The key point here is that if the product also lowers the combustion temperature for the soot to break up and leave - so it can passively recover the DPF whilst also unstick the EGR. Car drove much better afterwards and could feel the power and responsiveness come back. Still running on the AR6900 so that the EGR and inlet restores gradually over time. ## Features - FAST, SAFE AND THOROUGH CLEANING.

If you are having problems with how your diesel car is running or performance reduction, chuck a bottle of this in just before you fill up and go for a spirited drive (high revs). It’s the only additive I’ve found that does what it says on the bottle. ## Frequently Bought Together - Archoil AR6400-D MAX Pro Diesel Engine, Turbo, DPF Cleaner 400ml & AR6900-D 250ml - 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.
