AR9100 Oil Additive
Nano Lubrication Technology | For Use In All Engines

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.
AR9100 eliminates hard/cold start issues caused by HEUI injector misfires in 6.0L & 7.3L Power Strokes.
Upgrade Your 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)
Treat Rate
- Use 1.2 oz of AR9100 per quart of engine oil
- Use one 16 oz bottle to treat a Power Stroke

"Seeing this F-350 go from a cold-blooded, rough-running basket case to a truck that ran as smooth as it did the day it left the dealership definitely made believers out of us."

How it Works
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 that have built up in the engine. Continuous use of AR9100 will then keep the engine clean.
Extended oil drain intervals
Use of 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 should be used as a tool to determine if extended drain intervals are right for your application.
Power Stroke application
6.0L & 7.3L Power Strokes equipped 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.
MONEY BACK GUARANTEE
If AR9100 does not eliminate stiction issues in your 6.0L or 7.3L Power Stroke within 100 miles we will refund your purchase.
