Archoil AR9100 Friction Modifier Value Pack — Two 16 oz Bottles for 6.0L/7.3L Power Stroke, HEUI Stiction Relief & Wear Protection

Archoil AR9100 Friction Modifier Value Pack delivers two 16 oz bottles of AR9100 to reduce friction, stop HEUI injector stiction in 6.0L/7.3L Power Stroke engines, and improve lubrication across gasoline and diesel powertrains.

AR9100 is a concentrated friction modifier designed to be added to engine oil, gear oil, and other lubricants to create a solid lubricating boundary that reduces wear, quiets noise and vibration, and restores throttle response. This value pack supplies two full 16 oz treatments—each bottle treating a single 6.0L or 7.3L Power Stroke oil fill (13–16 quarts)—making it convenient for owners performing two service intervals or treating multiple vehicles.

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

AR9100 is formulated to target the boundary lubrication problem that causes injector stiction in HEUI systems, helping eliminate cold-start misfires and rough idle symptoms. Adding the recommended dose conditions internal surfaces and restores smoother injector motion without altering oil viscosity.

• Treat rate: one 16 oz bottle per 13–16 quarts for a complete Power Stroke service.
• Specifically helps HEUI stiction common in 6.0L and 7.3L setups.
• Reduces cold start misfires and improves idle consistency.
• Compatible with conventional and synthetic engine oils.

Can I use AR9100 in engines and driveline components besides Power Stroke?

Yes—AR9100 is not limited to Power Stroke engines. It’s safe for most gasoline and diesel engines and can be used in gearboxes, limited-slip differentials, hydraulic systems, and motorcycles when dosed per the label.

• Engine treat rate: 1.2 oz per quart of engine oil for conventional or synthetic oils.
• Gear, hydraulic, and power steering oils: 3.2 oz per quart for boundary protection.
• Works with limited-slip differentials when applied correctly.
• Non-restrictive with common seals and elastomers when used as directed.

What performance and protection benefits should I expect after treatment?

After proper dosing, AR9100 lowers internal friction to improve throttle response, reduces mechanical noise and vibration, and helps control operating temperatures under load. The additive also forms a wear-resistant film that supports longer component life and helps slow oil degradation.

• Restores throttle response and drivability.
• Reduces noise, vibration, and heat during heavy operation.
• Creates anti-wear barrier to protect critical components.
• Helps prevent sludge and deposits, extending oil life.

How do I dose AR9100 for different applications?

Treat rates vary by application: follow the stated ounces-per-quart guidelines to achieve the correct boundary layer. Accurate dosing ensures optimum protection without over-concentrating the oil.

• Engine oil: 1.2 oz of AR9100 per quart of oil.
• Power Stroke 6.0L/7.3L: one 16 oz bottle treats 13–16 quarts.
• Gear or hydraulic oils and power steering: 3.2 oz per quart.
• Apply during oil change for best distribution and immediate effect.

Who is this for: The Archoil AR9100 Friction Modifier Value Pack is tailored for truck owners, diesel enthusiasts, and professional technicians who want a targeted solution for HEUI injector stiction and a versatile friction modifier for broader lubrication needs. It’s ideal for people servicing 6.0L or 7.3L Power Stroke engines, owners of mixed fleets who want a universal treatment option, and anyone aiming to reduce wear, noise, and oil degradation across engine and driveline systems.
