AR9100 Oil Additive

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 (Ford 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 Ford 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.

Ford Power Stroke application

6.0L & 7.3L Ford 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.

AR9100 Frequently Asked Questions

How often should I treat my engine with AR9100?

To maintain the products benefits we recommend adding AR9100 to every oil change.

Can I add AR9100 to used oil?

Yes, but consider that if AR9100 is added to used oil which will be drained soon, the AR9100 will be drained with the oil shortly after adding it and would need to be replaced at the next oil change. If an oil change is coming up consider waiting until then to add AR9100 so it can be used for a full oil drain, or consider changing your oil when you add AR9100 so it goes in with fresh oil.

Do I need to drain some oil out when adding AR9100?

Yes, if you are adding AR9100 to an already full crankcase make sure there is room to add AR9100 by draining some oil out beforehand. Make sure not to add AR9100 to an already full crankcase, doing so will exceed your engines maximum oil capacity and can cause engine damage. For all Ford Powerstrokes remove ½ a quart (16 oz) of oil from the engine before adding a 16 oz bottle of AR9100. If you are adding AR9100 during an oil change make sure to use less oil so there is room to add AR9100. If your dipstick shows that the oil is below the maximum mark, you can usually add AR9100 without draining oil out.

For all Ford Powerstrokes remove ½ a quart (16 oz) of oil from the engine before adding a 16 oz bottle of AR9100. If you are adding AR9100 during an oil change make sure to use ½ a quart less oil so there is room to add AR9100.

Can I add to regular or synthetic oil?

AR9100 is compatible with both synthetic and conventional engine oil.

Can I add AR9100 to automatic transmissions?

No, We don't recommend using AR9100 in automatic transmissions.

My bypass filter filters down to 1 micron, will AR9100's additives be removed my bypass filter?

AR9100's extreme pressure additive is a nano material. The average particle size of AR9100 is 100 nanometers which is 1/10 of a micron, so AR9100 will pass through fine oil bypass filters without causing issues.

I just bought a brand new vehicle, when should I add AR9100?

AR9100 should be added to a new vehicle after it completes its break in cycle according to the owner's manual.

Will AR9100 void my warranty?

The Magnuson-Moss Warranty Act allows consumers to use additives of their choice without their warranty being voided, except for in circumstances where specific additives have been noted as incompatible.

Is it OK to use AR9100 in motorcycles with wet clutches?

Yes, use AR9100 at 1.2 oz per quart of engine oil in motorcycles with wet clutches. Check the owner's manual beforehand to ensure it does not specify not to use friction modifiers.

AR9100

I've been using the AR9100 additive in my 6.0 Powerstroke for the last 100k miles at every 5000 mile oil change with T6 Rotella. It has drastically cut down on warm up times before driving and I have zero hard start/below running temp engine injector issues. It has eliminated having to let the truck idle 10-15 mins before driving after the first start of the day, regardless of the temp.

Amazing

I was having horrible stiction problems with my 7.3 started hard had horrible injector clatter and truck shook really bad when cold I added archoil when I changed the oil started it up drove it around the block let it sit till the next morning and has fired right up and ran smoothly ever since with no injector noise
