Thanks again for your held........Iwill try that and get back to you.

Yeah, like someone else said, you are running your oil WAY too long.

Dino I run for 3k miles, syn i run for 5k miles.

Thanks Big Angry Hillbilly, I will do that in the future..3k

I change my oil every 6500 to 7500 miles and every second oil change I do the fuel and trans. filters. I was told by the mech who fixed my trans on a trip that the trans likes clean filters too.

I am not a spokesperson for there product in any way.....
my 6.0 was a tired oilfield truck that showed 134k on the odo and had over 6500 engine hours when i bought it I drove it and changed my oil religiously every 5000k and i have stiction issues at 165k ..... after 2000kms after adding hotshot secret to my motorcraft 10w30 oil change with oem filters same oil i have used since i bought my truck my stiction is almost non exsistant.......

that is my 2 cents

saw a spot for that on truck u today and became interested. I BUY TOO

What is this stiction y'all speak of? Sticking injectors? A chemical? Please inform me.

Stiction is like the initial friction between two objects. Think about a tire spinning on pavement. At first it takes a lot more power to break it loose, but once it's spinning, it's easier to keep it there. That initial "friction" is referred to as stiction between two objects. I'm not sure if it's the correct terminology to be using for an injector, but it's easy to understand.

Anyways, our injectors in these 6.0's do tend to get "sticky" as some people call it. The best product that I know of to rid this is Rev-X. Ask anyone who has used it. I have and it's literally like a miracle in a bottle.

Another observation I'd like to add... a fuel injector cleaner or anything that goes into the fuel system, isn't really going to take care of this. It's the oil side of the injector, so a good oil additive, good clean oil, and regular change intervals are all vital to the 6.0's injector performance.

I went every 5,000 miles for an oil change and changed the fuel filter every 10,000.
