Archoil Ultimate Diesel Kit – AR9100 Friction Modifier

Product Overview

The Archoil Ultimate Diesel Kit delivers a complete three-step solution for cleaning, maintaining, and protecting diesel engines of all types—whether you’re driving a modern high-pressure common rail (HPCR) vehicle or operating older mechanical injection systems. This comprehensive kit combines three specialized formulas: AR9100 Friction Modifier (16oz), AR6500 Diesel Treatment (40oz), and AR6400-D Diesel Fuel System Cleaner (12oz). Together, they work to restore engine performance, improve fuel efficiency, and extend engine life by targeting common diesel issues such as injector deposits, turbo lag, internal friction, and stiction in high-pressure oil-controlled injectors.

Designed for truck owners, fleet operators, RV drivers, and users of agricultural or industrial diesel equipment, the kit is effective across a wide range of applications. It supports smoother operation, quicker throttle response, and more consistent power delivery—especially in engines that have accumulated miles or show signs of reduced performance over time.

How It Works: Clean → Maintain → Protect

The kit follows a simple yet effective sequence. Begin with AR6400-D Diesel Fuel System Cleaner to remove stubborn deposits from fuel injectors and the combustion chamber. This deep-cleaning step helps restore proper fuel atomization and combustion efficiency. Next, use AR6500 Diesel Treatment at every fill-up to maintain a clean fuel system, prevent future deposit buildup, and control soot formation over time. Finally, add AR9100 Friction Modifier to your engine oil during your next oil change. This oil additive reduces internal friction, protects critical engine components, and addresses stiction issues in HEUI (Hydraulically Actuated Electronically Controlled Unit Injector) systems—particularly common in Ford 6.0L and 7.3L Power Stroke engines.

No tools or special equipment are required—just pour the fuel additives directly into your diesel tank and mix AR9100 into your engine oil at the recommended interval. The entire process is straightforward and fits seamlessly into regular maintenance routines.

Key Benefits

• Restores Injector Performance: AR6400-D effectively cleans clogged or coked injectors, restoring proper spray patterns and fuel delivery for smoother idle and improved throttle response.
• Revives DPF Function: By reducing soot and combustion deposits, the treatment helps maintain diesel particulate filter (DPF) efficiency and may reduce the frequency of forced regenerations.
• Reduces Turbo Lag: Cleaner combustion and reduced carbon buildup allow turbochargers to spool more quickly, delivering faster boost and better drivability.
• Improves Fuel Economy: Many users report a 10% or greater increase in miles per gallon (MPG) due to more complete combustion and reduced mechanical resistance.
• Eliminates Stiction in HEUI Injectors: AR9100 is specifically formulated to dissolve varnish and sludge that cause HEUI injector stiction—a common problem in 6.0L and 7.3L Power Stroke engines—helping restore proper operation and prevent recurrence.
• Enhances Lubrication and Wear Protection: AR9100 provides critical anti-wear protection for camshafts, lifters, and other high-stress components, especially in engines that rely on oil pressure for injector operation.

Technical Specifications

• AR9100 Friction Modifier: 16 fl oz – Engine oil additive

• AR6400-D Diesel Fuel System Cleaner: 12 fl oz – Concentrated fuel system cleaner
• Application: AR6400-D and AR6500 are added directly to the diesel fuel tank; AR9100 is mixed into engine oil at oil change
• Compatibility: Works with all diesel engines, including modern HPCR systems and older mechanical injection designs

Ideal Use Cases

This kit is especially valuable for diesel owners experiencing rough idling, hesitation, or reduced power. It’s a trusted solution for Ford Super Duty trucks with 6.0L or 7.3L Power Stroke engines, where HEUI injector stiction can lead to misfires and performance loss. Fleet managers use the kit to standardize maintenance across multiple vehicles, minimizing downtime and costly repairs. Agricultural and construction equipment operators benefit from improved reliability under heavy loads and extended service intervals. Whether you’re maintaining a personal pickup, an over-the-road semi, or a generator set, the Archoil Ultimate Diesel Kit supports long-term engine health and consistent performance.

Important Notes

Always use the products in sequence: start with AR6400-D for a deep clean, then use AR6500 with every fuel fill to maintain system cleanliness. Add AR9100 during your next oil change and continue with each oil service. The kit is formulated exclusively for diesel engines and should not be used in gasoline-powered vehicles. Store all components in a cool, dry place away from direct sunlight. No special handling or disposal is required.
