I've been using this oil for the past 10 years I own my Powerstroke never had an injector issue it's worth the money
This stuff works and it works quickly. Very pleasantly surprised!
After changing my oil and adding the Archoil to my 2006 60. I noticed after running it over o hundred miles. My sticktion problem with the injectors are 80 percent better on a cold start. I'm a ferm believer that it works.
I have a 6.0 that was running rough until it warmed up. I order arch oil and it arrived in a couple weeks. I changed oil and dump arch oil in. I ran it for around 50 miles. The next morning I was totally surprise that the engine idle nice and ran great. Arch oil is great.
I have been fighting the task of replacing several injectors on my 2006 6.0 due to surging and rough running.
I ran across the additive while searching and decided to try it.
I no longer have the surging issues and the truck is running as well as it ever has.
I am sold on this product.
