Archoil - AR9100 16oz. Friction Modifier Oil Additive Powerstroke Diesel

---1 Gallon--



  • 1 - 1 Gallon Bottle of Archoil AR9100 Friction Modifier Oil Additive (Commonly used in the 6.0L & 7.3L HEUI Injection systems but will work with other oil systems as well. We use this in our personal vehicles as well as in the shop due to the effectiveness and price compared to other popular oil additives on the market.

Stiction: CAUSE and EFFECT

Stiction is the static friction that needs to be overcome for one surface in contact with another to move. Stiction, in this case, is often the result of oil coking and carbon buildup inside the spool valve - the vital component that allows high-pressure oil (required to actuate the fuel side of the Power Stroke HEUI injector) to enter the injector. This gummy, oily residue hampers oil flow through the valve, and when the spool valve cannot open and close as precisely as it needs to, stiction is at work. It leads to inconsistent fuel quantities leaving the injector nozzle, and poor fuel atomization occurring in-cylinder. Common symptoms are hard starting, rough idling, and oftentimes a truck that's smoking while it warms up in the driveway. If neglected long enough, stiction can cause irreparable spool valve bore wear, with expensive injector replacement being the only permanent solution.

Powerstroke Diesel Application
AR9100 fixes injectors in Ford PowerStroke 6.0L and 7.3L trucks and other HEUI Injection vehicles (Navistar T444E and VT365) by cleaning and lubricating stuck spool valves. Stiction is eliminated along with associated cold start problems including rough idling, cylinder misfires and loss of power and acceleration. We are so confident in these results we offer a 100% money back guarantee if our product does not eliminate HEUI injector stiction issues within 100 miles. One 16 oz bottle of AR9100 treats up to 16 quarts of engine oil and is sufficient for one PowerStroke treatment.

Other Uses
AR9100 has been used to eliminate piston slap noise in Chevy LSX engines, to clean out built up sludge in Toyota VVT-i engines and to allow agricultural equipment to operate throughout the day without requiring cool down periods. AR9100 will also protect differentials, gearboxes or power steering systems from overheating and wear during aggressive operation.
