Good question.... an 08 shouldn't need that kind of treatment yet unless you REALLY put crazy miles on it.

Or run really crappy gas through it......

What would you expect the stuff to do anyway? How would anyone know it did anything?

Seafoam has worked for me on my ZJ and my Yukon. It helped smooth out the rough idle and also got rid of some hesitation. I do Seafoam every other oil change. It's fine to do on a low mileage new vehicle as it helps reduce carbon buildup.

[Spurshot]

Many moons ago, there were a number of products that claimed carbon removal. After having several engines with water injection for anti-detonation and having torn them down, I would simply use a bit of water to remove carbon. But, then the Seafoam is probably cheap enough.

 

If I had a rough idle and hesitation, I'd probably pull the plugs and read them and maybe clean or replace them. But if this stuff can do that without pulling the plugs, that 's great.

There's a far easier way to reduce carbon build up; just do a WOT run or two every once in awhile, to blow it out the tailpipe

 

As long as you're following regular oil change intervals (as in, not listening to that stupid OLM) and using a quality oil and quality gas, you shouldn't have any real issues with carbon anyway. I just don't see the point in doing SeaFoam unless you're at a higher mileage, say 100K+

I tried Seafoam through my 06 a while back and honestly didnt notice that big of a difference. I put it through my oil, gas, and the intake but I was still getting the same response and/or hesitation. I changed the plugs out with some NGKs and everything smoothed out. I think items like these lean more to the placebo effect than anything else. Or if a motor is so far gone that almost anything can help it.

[dwhults]

I guess YMMV. I KNOW it wasn't a placebo and it did actually make a difference. Your plugs were obviously shot so that's why replacing them helped.

Also try cleaning your MAF sensor and your throttle body. I cleaned the TB and the MAF sensor on an 03 Altima and it made a world of difference. I also cleaned both on my 08 Silverado and it helped a little but they were not that dirty to begin with. I was changing my oil and just started messing around since I was bored.

 

I put some Seafoam through my girlfriend's A4 and it made a world of different. Gave it a smoother idle and acceleration. The stuff works pretty good if it needs it.

I prefer to not put something in the tank, intake, or crankcase that I don't know all the side effects of or something that the factory hasn't recommended. I won't refute the effectiveness, but I'm not convinced I need to use this in any of my vehicles. There used to be a big following of people that used Marvel Mystery Oil in the same manner.

Although I have never used it, From what I have read from reliable sources...Its pretty good stuff, as is Auto RX engine cleaner. and I am not big on additives either. The guys on bobistheoilguy.com sware by auto RX for sludged engines. (I have never had a sludged up engine, even when I used Pennzoil)

[Spurshot]

Like you, I've never had a sludged engine that needed any special additives/treatments. I've always used good brand detergent oils that I changed often. When I have torn down some of my engines, I never saw any buildup. So, I'm not inclined to use any of these products.

 

I may be digging into my 99's engine, with 215,000 miles on it, very soon to do the head gaskets. It's had Mobil 1 in it since the first change and has been changed at very short intervals (for synthetic). It'll be interesting to see the innards of it. I've heard stories that the insides of similar aged engines that used Mobil 1 were very clean.
