Archoil AR9100 Friction Modifier

Archoil's AR9100 oil additive is suitable for use in all diesel and gasoline engines (including Cummins, Duramax and Power Stroke). AR9100 forms a solid boundary lubricating film that improves performance and protects engines, gearboxes and hydraulic systems and eliminates hard start/cold start issues caused by HEUI injector misfires in 6.0L & 7.3L Power Strokes.

Upgrade Your Engine Oil

  • Increases power and response

  • Reduces friction and provides anti-wear, extreme pressure and anti-corrosion protection

  • Reduces engine noise and vibration

  • Protects engine during cold starts

  • Cleans and prevents sludge/varnish deposits

  • Extends oil drain intervals

  • Fixes HEUI injector problems (Power Stroke and others)

Extreme Pressure/Anti-Wear Protection

AR9100's extreme pressure (EP) additive forms a solid boundary lubricating film on friction surfaces, providing excellent load carrying ability under the most extreme operating conditions. AR9100 also incorporates highly polar esters that stick to metal surfaces, ensuring good penetration and protection of all engine components.

Reduced Friction

The lubricating film formed by AR9100 reduces friction, improving efficiency and power. Reduced friction means a system will develop less heat and run more smoothly and quietly.

Engine Deposit Reduction

AR9100 will gently remove and disperse any sludge, varnish and carbon deposits built up in the engine. Continuous use of AR9100 will then keep the engine clean.

Extended Oil Drain Intervals

Using AR9100 typically extends oil drain intervals. AR9100 increases the TBN (total base number) of your oil, which will help prevent it from becoming acidic during extended oil drain intervals. AR9100 also improves the oxidative stability of engine oil, reducing the rate of degradation. Oil sampling is a recommended tool to determine if extended drain intervals are suitable for your application.

Power Stroke Application

6.0L & 7.3L Power Strokes with HEUI injectors often suffer from hard starting, rough idling, reduced power and response and smoking until the engine is warmed up. Add a 16 oz bottle of AR9100 at every oil change to eliminate hard start and drivability issues caused by HEUI injector misfires in 6.0L & 7.3L Power Strokes.


If AR9100 does not eliminate stiction issues in your 6.0L or 7.3L Power Stroke within 160 kilometres (100 miles) we will refund your purchase.
