this product is the shit. i have owned 5 ford 7.3 [ best diesels engines ford ever produced] only they weren't good cold weather starters. after using archoil friction modifier my rigs [2-7.3] start up down to 0 degrees. no injector problems. AR9100 try it.
I have been using this product since I put a new motor in my 04 and it does and amazing job
Works great! Easier starts and no surging going down the road. I thought I was going to have to replace injectors, but my truck runs great now.
The AR9100 really makes a difference on my 2005 F250 6L. I have been using this since 2013 and do not plan to stop. I had to replace my injectors twice before finding this. My mileage was poor and the truck shook, especially in winter, if it even started.
Since using it, my mileage returned, I have had no major repairs, the engine no longer shakes and I can start the truck in temps down to -10F.
Truck has over 200k on it and though I don't drive it as much, it still starts right up every time.
I thought I would add this to an old Subaru that really shook at idle. The shaking stopped completely within 50 miles and the mileage went from 24 mpg to 28 mpg. Sometimes I accidentally "start" the engine while it is running. It is very quiet now and has over 210k on it.
Very seldom will i write a review for any of my purchases but this is an absolute amazing additive! I had taken my 6.0 power stroke to a couple of shops to which each of them said that the injectors needed to be replaced. The average price for this replacement was $4500.00. My truck had about 180k on it and the previous additive recommended by a diesel repair company was no longer doing anything. After adding the Archoil I was expecting it to take awhile to see any improvements but this stuff worked immediately. I am so impressed with the Archoil additive that i would recommend it to anyone with a power stroke diesel. It is the greatest additive that i have ever used!
