"Attention Power Stroke Owners - AR9100 Friction Modifier is 100% GUARANTEED to eliminate STICTION in diesel vehicles with HEUI injector technology within 100 miles or your money back!" - Bill Hewitt
I have a 2000 F350 7.3 Powerstroke. 122,000, never used to tow anything. Used by a pool service company. I bought it a few years ago with 170,000.
I had a glow plug go bad. Here in So Cal, worked fine on 7 glow plugs. Went to get it smog tested. It fail due to service light being on for bad glow plug. Found a so called, Power Stroke expert here in LA. Got it back and ran horribly. Then service light came on with a code for a bad fuel injector. I had just paid over $2000 for the glow plugs. Tried all the heavy duty fuel system and injector cleaners on the Autozone shelves. No change. I was made an appointment to have injectors replaced. Looking at another $3000.
So I watched the Powerstroke expert on YouTube. He suggested your products. I bought the bundle. Under $90. I didn't have any faith that it would work. Two or three tanks later, started sounding better. Then when I reset the service light for the 100th time, the light stayed off. It has been off for quite a while. So your products saved me $3000+. Thank you! Thank you! Thank you! What amazing products you produce. Your products will now always be in my truck!!!
AR9100 Friction Modifier
No Archoil product has ever not performed as described.
After using Archoil, instant starts from the injectors. Cures long cranks and smooth idle. Use it every oil change. Satisfied 6.0 owner.
Helps to quiet down the injectors and provides better lubrication. I once had developed some stiction issues with my 05 Excursion at about 120k miles. But they went away when I started using this.
