Archoil AR9100 Friction Modifier – Value Pack Two 16 oz Bottles for Power Stroke HEUI Stiction Repair & General Friction Reduction

Archoil AR9100 Friction Modifier Value Pack delivers two 16 oz bottles designed to eliminate HEUI injector stiction in 6.0L and 7.3L Power Stroke engines while providing broad anti-wear and friction reduction benefits across gasoline and diesel applications.

If your truck shows cold-start misfires, rough idling or sluggish throttle response tied to HEUI injector stiction, AR9100 is formulated to address that specific problem while also serving as a general friction modifier for engines, gearboxes and hydraulics. Each 16 oz bottle in this value pack treats one Power Stroke service (13–16 quarts), giving you two complete treatments for heavy-duty maintenance or for use across multiple vehicles and components.

How does AR9100 stop injector stiction in 6.0L and 7.3L Power Stroke engines?

AR9100 contains friction-reducing chemistries engineered to restore smooth injector movement in HEUI systems. By improving lubricity at the injector interfaces, it reduces the cold-start sticking that causes misfires and rough idle without altering injector hardware.

• Targets HEUI injector stiction common in 6.0L and 7.3L Power Stroke engines
• One 16 oz bottle treats one 13–16 quart oil change
• Helps restore consistent injector operation and throttle response

Can I use this product in engines and other driveline components?

Yes — although it’s promoted for Power Stroke HEUI fixes, AR9100 is compatible with both diesel and gasoline engine oils and can be used in gearboxes, limited-slip differentials, motorcycles, hydraulic systems and power steering. Follow the recommended dosages to match the fluid type for best results.

• Engine oil treat rate: 1.2 oz per quart for conventional and synthetic oils
• Gear, hydraulic and power steering fluids: 3.2 oz per quart
• Limited-slip and motorcycle applications follow the engine oil rate

What performance improvements can I expect after treatment?

AR9100 reduces friction and forms a lubricating barrier that helps improve throttle feel, lowers noise and vibration, and stabilizes operating temperatures under load. While results vary by condition and severity, many users notice smoother idle, quicker response and quieter operation after treatment.

• Improves throttle response and drivability by reducing internal friction
• Quiets noise and vibration from high-load contacts
• Helps reduce heat generation and surface wear for longer component life

How does using AR9100 affect oil life and component protection?

AR9100’s lubricant chemistry helps slow oil degradation and discourages sludge and deposit formation, which supports longer oil service intervals when used as part of a regular maintenance program. It also creates a protective film on metal surfaces to reduce wear and protect moving parts.

• Forms a solid lubricating barrier to minimize metal-to-metal wear
• Slows deposit formation and oil breakdown under typical operating conditions
• Supports component longevity when combined with scheduled oil changes

Who is this for: The Archoil AR9100 Value Pack is aimed at owners and technicians who want a targeted HEUI solution for 6.0L and 7.3L Power Stroke trucks and a versatile friction modifier for broader applications. It’s a good choice for fleet managers, diesel enthusiasts and anyone looking to reduce injector stiction, improve drivability, and add anti-wear protection across engines, gearboxes and hydraulic systems.
