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.

Did quite down the motor some. But unfortunately for me the hard starts did not get any better. Truck starts and runs rough for about 3-5 min and smokes until it gets a little warm. I will try this again next oil change and possibly shim my injectors and do new o rings on all them.

It works! Last oil change I flushed my HPOP reservoir with Seafoam, then added half & half synthetic Rotella (hard to find right now) and ArchOil to the reservoir. The engine now runs smoother, quieter and starts with ease. Hopefully this will preserve the injectors until the top-end O-rings (all of them, HPOP to the pedestal) need to be replaced. I'm convinced that Archoil not only works but will help prolong the life of the engine.

archoil AR9100 Friction Modifier for 7.3 AMAZING

Used archoil AR9100 Friction Modifier and I am amazed at the starting/performance and fuel mileage on all my 7.3 engines. (1999 7.3 291,000 miles/ 1997 7.3 134,000 miles/ 1996 7.3 300,000 miles). Bought more for my family that all have 7.3 Powerstrokes from 1995 through 2003.

Great results

Have used archoil products in our 6.0L king ranch for years and the truck runs as good now (178,500 miles) as it did when new with no major repairs. AWESOME PRODUCTS.

Sure starting

Waiting for my next oil change to use my latest order, but the shop that I trust with my truck has used this in the past on my truck and it solved all my hard starting issues during cold weather. Great stuff!
