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.

Great Stuff

I have a 2000 F250 with the 7.3. Just moved to Idaho. My truck hates starting in anything less than 40 degrees. Hard starting crackling rattling and smoking. After adding Archoil, she starts like a dream and the rattle is gone, which bothered me the most. Great product. I’ll be using it in all my oil changes

Good product.

I will be using this in every oil change. Everyday when I started my truck it would blow thick white smoke for about a minute or so and now it starts with no smoke at all. Very impressed

Works as advertised

One of our old 7.3's has been hard to start for some time now. Lots of white smoke and no start at all of it's even slightly cold out.
Put a bottle of Archoil in the oil and ran it for work that day. Next day it started like a new truck. No smoke and fired off instantly. I am very impressed and needless to say we will be using the product in both our 7.3's from now on.
