I have heard it is bad for the 2003 and up common rail because of the alcohol in it?? Then I have heard it is EXCELLENT to use for rough idle or carbon build up on the injectors...

big discussion on this subject last week. do a search. it contains alcohol,like many other injector cleaners-using it occasionally will help. over doing it like anything else- is bad. my local cummins shop uses BG products-which also contain alcohol. everything in moderation!

Seafoam
I use it at fuel filter change. Drain the filter housing and add 3/4 can, the rest in the tank. Cycle the ignition switch three times and then start. Never a problem.

But I think it works a little TOO well. If you read the can, it tells you that you can add it to your oil to clean the engine out. But it also says you should do this right before an oil change and NOT to leave it in for any length of time.
Here's my reasoning: the deposits or dirtiness in an engine or fuel system took time to accumulate. They didn't happen overnight. Thus, the best way to remove them is gradually as well. Otherwise, you risk major chunks of stuff floating around, plugging things or causing other kinds of mayhem.
I've had exceptionally good results with products from Lube Control, Inc (www.lubecontrol.com) in both my oil and my fuel. I found out about them from www.bobistheoilguy.com Both my fuel system and the engine are incredibly clean-- no varnish or buildup of any kind (not anymore, anyway!). But the cleaning action was gradual and spread out over a couple thousand miles. Thus, no harm to the engine or fuel system.
**I get nothing from Lube Control if you buy their stuff. I'm a very happy customer and think others can benefit as well**

I used Seafoam in my tank and drove to LA. No change in injector sounds or any noticeable improvement in idle.
A week later I drove back from LA, but adding a full bottle of Power Service Diesel Kleen. A tank of fuel later I had a noticeably smoother idling engine. No better fuel economy, as the bottle claimed.
Who knows, maybe they both had an effect? But only the PS made an audible difference.
I also would be apprehensive about running the motor on straight solvent.
