Depends on your temps, and only when you're first starting. Personally I use 5w-40 in the winter so it's easier to crank through.
I add diesel kleen every other tank, and it keeps things purring. I would not just throw any cleaner in there, do some research. When it's running rough, do you start and go, or do you wait 5-15min for it to warm up a bit? Check the simple stuff first, like air filter, fuel filters, to make sure it's getting fuel and air. check FICM voltages, it's kind of annoying to do but can be done on your own in about 15-20min, tops.

new fuel filters 5k ago
new ARE filter 1000k ago
no way to check ficm, i guess i will have to run it by mech shop, to have him check it and tell me what it is..
he recommended me using the BG, one in the fuel other one goes into oil, let sit and idle for 2 hrs, then change oil....was trying to get input from others who have run different cleaners...

No, NO, NO. Should not do that to a 6.0. Get your ficm voltages, check battery voltages. Check fuel pressure. Worst thing to do to a 6.0 is let it idle for two hours. Your better off to belly up and take it to a Ford dealer and get it right the first time. Your mechanic is leading you down the path of eternal headaches. doesn't seem to be familiar with the 6.0. JMHO.

FICM check only requires a voltimeter-20 bucks at a hardware store. Anybody that has a vehicle and knows how to lift the hood should own one anyways!! :-) I couldn't farm without one, I'd be lost...
Take the 2 bolts out of the degas, remove the smaller hoses off that go into the top, pull it out of the way, 2 torex screws to take out of the plate on the FICM and you're ready to test.

the guys are right. for a rough start, it's best to check the ficm cos low ficm voltage means tat it's dying. it can be repaired. i believe it's ficmrepair.com
on their website, there is a link to hot shot's secrets. it's an injector cleaner originally designed for international truck and engines. it wont hurt to take a look.
hope the info helps.
also, u'll need to check ur batteries and ur alternator too, if ur ficm is bad. they seem to be chained together.

You also need to check for codes and a lot of the standard code readers can't read what the specialty dealers computers can read. I'm not pushing dealers but if you'r not comfy with the 6.0, a dealer can be much cheaper in the long run. Fix it right, fix it once.

Hey guys dont forget about the famous "injector stiction". I dont know of anyof you remember, but i had the exact same problem and thats what it turned out to be. I put my money on that. But like they said do all the easy tests first. Ficm test is easy. And then go to your local auto parts store and hav them check for codes. If everything checks out go get the most recent program update done on the truck. This usually equals out to 1 hour of shop time.

I think it was the venerable Cheezit who pointed out once that the fuel pressure at the injector nozzle was somewhere in the area of 26,000 PSI, and something blocking up the injector nozzles that can withstand 26k PSI of fuel pressure is not going to be removed by any chemical.
That doesn't mean that fuel additives are not useful, but not necessarily for cleaning injectors.
