Seafoam..
How is this stuff? I just put some in my g/f's pt cruiser...always heard it was great stuff...would it hurt to put some in my Z after 15k miles?

I used it in my old 97 Eclipse. It improved idle. You can inject it into the throttle body or one of the vaccum hoses leading into the intake manifold. Poor it in slow, to avoid flooding the engine and shutting it down. You'll see alot of smoke come out the back. It was worth the few bucks to me.

I've seen some people do a combination of putting it in the gas tank, sucking it through a vacuum hose into the motor, and adding some to your oil all at the same time. Ofcouse after a short period of time you'd need to change your oil.

I've heard both sides of the Seafoam argument.. half says it works great and cleans up the idle, the other half says that on older engines it will break down the seals that are held up with oil and you may start getting leaks. Don't know which is truth, just relaying what I have read. I would think that an engine being held together by its own oil buildup is on it's last leg anyways.

the biggest down side i see is all that crap getting caught in the cat.these top end cleaners have been available thru g.m. since before cats existed and after they started putting cats on they recommend dropping the exhaust during the treatment!

I just dumped some in my gas tank, I've only got 63k miles on mine.
In the past, and on much higher-mileage cars I've owned, I've sucked it in through the brake booster vacuum hose.
The stuff works great, although only if you realize the following:
1. The crap n your cylinder goes somewhere...It tends to foul up spark plugs
2. It gets in your oil
3. If could damage your cat converter if you get the mix too rich
So generally speaking, after you're done, change your spark plugs and also your oil.
Dumping it in the gas tank is not going to cause nearly as adverse reactions because it will be so diluted.
Even the OEMs do this...Mopar has their own formulation called something like Combustion Chamber Cleaner or something like that. Same philosophy as with seafoam.

Exactly. Ive used it alot on different cars. Worked well for me everytime. The more smoke the better. I did it in three steps. In thirds, goes in the gas tank, in the oil, and directly in the cylinders.

But do some research, it's your baby, make sure it's a good choice for you and the Z.

I just did this to my MB C230K with 148k on it. I put a third in the vac lines and the rest in the tank(i have heard more then a few times thats it does hell to your oil. Started it up, craped out a huge smoke cloud for a few minutes, and then i went out for a drive. If kept smoking for a few more minutes, but stopped. I noticed a smoother idle, a better a/f ratio, and it feels to pull a but better. Now im not saying that i gained 40+hp or something, but it feels better. Now im waiting for what i put in the tank to run though and see what the difference it. for ~6 buck, i would say it is worth it, but not in the oil.
