Didnt work for me
My 04 6.0 starts better, but still has some stiction issues. I'm going to add archoil again to the next oil change. Hopefully that will clear it up.
Fixed my cold start problem
04 6.0 hard starting when it was cold out. You start and shut off. It would run really rough and cut back until the EOT was abt 140°. Had injectors test on a contribution test (engine was warm) they all tested good. Was did a fresh oil change it T-6 and archoil. Drove it very little that day less than 30 miles. next morning for work its 42° . Truck started so good i was very surprised. In shock considering i had already used hot shot secrets. It helped my truck with the striction issues. If you are like me having issues it will help if thats the ONLY issue you have. I also changed my FICM. Just bc the voltage reads good doesnt mean its performing like it should. Do your research is could save you tons of $$$. Its not always the injectors.. hope this helps someone
I'm not impressed so . It hasn't made a difference yet. Not giving up yet. I will get it some time.
