I've been using this since I purchased the truck from Powerstroke and have not had any problems. Seems to do the job as I pull an 12000 lb trailer and am able to just keep on trucking.. Don't see how I could use anything else. Great stuff!
It helped with my cold start issues recommended
Using it now in my 6.7 with a new engine. I run commercialy about 10,000 miles a month.
2006 6.0 was starting rough after the full engine rebuild, I did reuse my factory Ford injectors since they were operating normally before the year down. Started using fuel additive from archoil to see if that would loosen them up but no luck, changed the oil and added Archoil friction modifier and she starts perfectly now.
Before Archoil AR9100 the engine had a knocking sound but it has disappeared. She sounds great now. Can’t wait to use the fuel additive!
