Archoil Diesel Additive Kit — AR9100 + AR6500 + AR6400-D (16oz/40oz/12oz) for Clean, Protect & Friction Reduction

This kit combines Archoil's AR6400-D Diesel Fuel System Cleaner, AR6500 Diesel Treatment, and AR9100 Friction Modifier into a single maintenance routine that targets fuel-system deposits, soot control, and friction inside the engine. The components are formulated to work together: deep clean the fuel system, keep it stable during operation, and add anti-friction protection to engine oil. Each product is simple to use and suitable for a wide range of diesel engines, including modern high-pressure common-rail systems.

How do I use these three products step-by-step?

Start with AR6400-D to remove deposits and contaminants from injectors and fuel lines, then switch to AR6500 for ongoing maintenance at every fill-up, and finally add AR9100 to engine oil at your next oil change to reduce internal friction. The sequence is Clean → Maintain → Protect for predictable, ongoing benefits.

• Use AR6400-D once to deep clean fuel system before maintenance.
• Add AR6500 at each fuel fill to control soot and deposits.
• Add AR9100 to engine oil at oil change for friction reduction and anti-wear protection.

What improvements can I expect in engine performance?

You can expect smoother idle, crisper throttle response, and fewer fuel-related hesitations as deposits are removed and kept under control. Over time, cleaner injectors and stabilized combustion typically reduce soot accumulation and improve fuel efficiency consistency.

• Smoother running from cleaner injectors and fuel lines.
• Improved throttle response and steadier power delivery.
• Reduced soot-related performance loss when AR6500 is used regularly.

Will this kit work with my vehicle and fuel system?

The Archoil trio is formulated for use in all diesel engines and equipment, including modern HPCR/common-rail systems and older mechanical diesels. Product chemistry is engineered to be fuel-compatible and safe for typical engine components when used as directed.

• Compatible with modern high-pressure common-rail diesel engines.
• Safe for turbocharged engines, diesels with DPF, and older diesel designs.
• Suitable for vehicles, trucks, generators, and off-road equipment.

How does AR9100 friction modifier help the engine oil?

AR9100 is an oil-additive friction modifier that reduces metal-on-metal friction and provides anti-wear protection to critical moving parts. It helps eliminate injector stiction in affected systems and enhances lubrication film strength under load, improving longevity when added at oil change intervals.

• Reduces friction for smoother engine operation and quieter performance.
• Provides anti-wear protection for bearings and other moving parts.
• Addresses injector stiction issues in certain Power Stroke and HEUI systems.

Who is this for? The Archoil Ultimate Diesel Kit is aimed at diesel vehicle owners, fleet managers, and equipment operators who want a systematic approach to fuel-system cleanliness and long-term engine protection. It suits anyone maintaining daily-driven diesel trucks, commercial fleets, agricultural machinery, or performance diesel enthusiasts seeking better response and reduced mechanical wear without complex installations.
