AR9100 Friction Modifier solves misfire and cold start issues in 6.0L & 7.3L Power Strokes

100% Money Back Guarantee

If AR9100 does not resolve stiction issues after 100 miles

The Problem

Deposits and wear in the HEUI injector causes the injector to become stuck due to static friction, or 'stiction', and can prevent the injector from firing. This causes 6.0 & 7.3L Power Strokes to suffer from hard starting, rough idling, reduced power and response, bucking and smoking until the engine is warmed up.

The Solution

Add a 16oz bottle of AR9100 to every oil change to eliminate hard start and drivability issues caused by HEUI injector misfires in 6.0l & 7.3l PowerStrokes. AR9100 will clean out HEUI injector deposits and creates a friction reducing film inside the injectors to ensure all eight injectors fire every time.

How it Works

HEUI injectors use oil pressure to raise fuel pressure inside the injector. A High Pressure Oil Pump (HPOP) feeds oil from the crankcase to the injector where a 'Spool valve' ('poppet valve' for 7.3l) opens allowing hydraulic pressure to raise fuel pressure and fire the injector. Engine oil is exposed to very high temperatures and pressures in the Spool valve and degrades, forming deposits. These deposits cause excessive wear. Deposits and wear create static friction inside the injector, or 'Stiction', which can prevent the injector from firing.

A blend of esters combined with our additive package remove and disperse deposits while AR9100 forms a friction reducing solid boundary lubricating film on the bore of the 'spool valve'. By removing deposits and reducing friction, AR9100 eliminates stiction issues and ensures they do not return.

"The next morning, following a 15-degree night during which the truck once again sat outside, it fired right off and idled smoothly. 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.

100% fix for ford 7.3

Salvation for the 6.0L

Works great! Easier starts and no surging going down the road. I thought I was going to have to replace injectors, but my truck runs great now.

Works on Cars Too!

The AR9100 really makes a difference on my 2005 F250 6L. I have been using this since 2013 and do not plan to stop. I had to replace my injectors twice before finding this. My mileage was poor and the truck shook, especially in winter, if it even started.
Since using it, my mileage returned, I have had no major repairs, the engine no longer shakes and I can start the truck in temps down to -10F.
Truck has over 200k on it and though I don't drive it as much, it still starts right up every time.

I thought I would add this to an old Subaru that really shook at idle. The shaking stopped completely within 50 miles and the mileage went from 24 mpg to 28 mpg. Sometimes I accidentally "start" the engine while it is running. It is very quiet now and has over 210k on it.

The greatest additive I have ever used

Very seldom will i write a review for any of my purchases but this is an absolute amazing additive! I had taken my 6.0 power stroke to a couple of shops to which each of them said that the injectors needed to be replaced. The average price for this replacement was $4500.00. My truck had about 180k on it and the previous additive recommended by a diesel repair company was no longer doing anything. After adding the Archoil I was expecting it to take awhile to see any improvements but this stuff worked immediately. I am so impressed with the Archoil additive that i would recommend it to anyone with a power stroke diesel. It is the greatest additive that i have ever used!
