AR6400-D is formulated to be poured directly into the fuel tank; one 12 oz bottle treats 30–40 gallons and is intended for periodic use to remove performance-robbing deposits throughout the fuel system. It pairs with Archoil AR6500 for ongoing maintenance that addresses lubricity and cetane shortcomings often found in pump diesel.\u003c\/p\u003e\n\n\u003ch3\u003eHow does AR6400-D clean injectors and improve combustion?\u003c\/h3\u003e\n\u003cp\u003eThe formula contains concentrated detergents and deposit-dispersing agents designed to break down varnish and carbon on injector tips and spray orifices. Cleaning restores proper spray patterns and atomization for more complete fuel burn without changing engine parts.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eTargets injector deposits that cause poor spray or dribbling\u003c\/li\u003e\n  \u003cli\u003eImproves atomization for smoother idle and better throttle response\u003c\/li\u003e\n  \u003cli\u003eOne bottle treats 30–40 gallons for full-system exposure\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill AR6400-D help my turbocharger and DPF performance?\u003c\/h3\u003e\n\u003cp\u003eYes—reducing upstream deposits helps prevent carbon buildup that can impair turbo response and increase DPF loading. By clearing fuel-related deposits, the product supports steadier boost behavior and can reduce the frequency or severity of DPF regenerations driven by soot accumulation.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eControls deposit formation that influences turbo spool and boost recovery\u003c\/li\u003e\n  \u003cli\u003eLessens soot\/soot-precursor buildup to support cleaner DPF operation\u003c\/li\u003e\n  \u003cli\u003eHelps maintain consistent combustion temperatures that aid regeneration\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow do I use AR6400-D and how often should I treat my tank?\u003c\/h3\u003e\n\u003cp\u003eUsage is straightforward: pour the 12 oz bottle into a nearly full tank, then drive normally to circulate the product through the system. For proactive care, use every 5,000 miles or as needed when you notice performance loss; occasional treatments after heavy-duty or high-mileage use are also effective.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePour entire bottle into fuel tank; one bottle treats 30–40 gallons\u003c\/li\u003e\n  \u003cli\u003eDrive normally to allow the formula to flow through injectors and fuel components\u003c\/li\u003e\n  \u003cli\u003eRecommended interval: about every 5,000 miles or based on observed drivability\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat maintenance should I follow after using this cleaner?\u003c\/h3\u003e\n\u003cp\u003eAfter a deep clean with AR6400-D, follow up with a daily-use diesel treatment to preserve results. Archoil AR6500 is recommended at every fill-up to maintain lubricity, control deposits, and help sustain cetane levels, reducing the need for frequent deep clean cycles.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eUse AR6500 at each fill-up to extend cleaning benefits\u003c\/li\u003e\n  \u003cli\u003eRegular treatments reduce frequency of heavy clean cycles\u003c\/li\u003e\n  \u003cli\u003eCombine with routine fuel filter and service intervals for best outcomes\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for? AR6400-D is aimed at diesel truck, van, and equipment owners who want to restore or maintain fuel-system performance without disassembly—especially those noticing rough idle, sluggish response, increased fuel smoke, or more frequent DPF activity. It's suitable for personal and commercial diesel vehicles, including turbocharged engines, and for owners who prefer in-tank chemical maintenance paired with a follow-up treatment plan.\u003c\/p\u003e\n\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: How much fuel does one 12 oz bottle treat?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: One 12 oz bottle treats approximately 30–40 gallons of diesel.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I use AR6400-D with a turbocharged diesel?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes, it is formulated to reduce deposits that affect turbo response and overall combustion.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Archoil","offers":[{"title":"Default Title","offer_id":67588572938425,"sku":"B072BWR7J3","price":73.3,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0822\/3765\/3177\/files\/archoil-ar6400d-front-label.jpg?v=1790520089","url":"https:\/\/redleafauto.ca\/products\/archoil-diesel-fuel-system-cleaner-ar6400-d-12-oz-injector-turbo-dpf-deposit-cleaner-for-restored-power","provider":"Redleaf Auto","version":"1.0","type":"link"}
