"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."
"Archoil is the Real Deal"
Excellent service, as expected!
2001 7.3 starts with no loping at cold temperatures. Product performs as advertised. Been using it for a year now.
I have been using it for 3 years in all my trucks. especially the 7.3 trucks. i got a truck with 370,000 miles all original never replaced a injector. it would not start when it was below 50 out . I started to use this oil becuse Bill at powerstroke.help.com recommended it for stiction. I put it in at 236,000 and now it has 370 on her and will fier up in the low teens with no plug in . It litterly made my truck run again and start THANKS archoil buyer for life . By the way when i add mine i install it in the hpop resivore by removing the old hpop oil and installing the ar9100 so injectors get a full concentrated blast
Works great! Been using ar9100 7+ years. Makes a drastic difference in cold weather starts, but I use it year round. Thought I'd go without it last oil change just to see how engine/injectors would behave, they didn't appreciate it. So in went ar9100 and yep, smoothed out the cold starts.
This additive is no joke, it definitely helps against injector stiction and added protection for engine lubrication in extreme heat or cold.
I own a 2002 power stroke with a 7.3 in it and living in the U.P. of Michigan winters are pretty hard on Diesels , if I don’t use archoil I might as well have a boat anchor parked in the driveway. After 16 ounces of 9100 at oil changes the truck starts and sounds like a new truck again . THANK YOU ARCHOIL !
