AR9100 Friction Modifier is proven to solve misfire and cold start issues in 6.0 & 7.3L Power Stroke vehicles.

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.

Diesel Power Archoil Article

"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.

Engine runs more smoothly

2012 F250 6.7 Turbo Diesel. Engine and turbo runs much more smoothly with Archoil.

Piece of mind

I use 9100 in my 03 6.0 no stiction but it’s good piece of mind knowing it’s in the oil


My truck loves this stuff!

Good stuff

Purchased this product to use in my 1999 F250 7.3 powerstroke. The order was shipped and arrived in just a couple days. I find a lot of the claims of this solving hard starting in the 7.3 power stroke are a bit overstated. My power stroke still starts hard in the cold weather. I do find that once it starts it doesn't blow a lot of white smoke, and it doesn't run rough, so I do agree with those claims. Still starts hard on cold mornings though.

2005 f250 stiction

Still a little Stiction but goes away a lot quicker
