I noticed no difference in feel on my 55k mile car. Unless you don't change your oil regulary or your car has over 100k miles I wouldn't bother.

Also follow the instructions. It says something like x amount of seafoam to x amount of gas.

Did you change the plugs?

never had any harm using Seafoam in gas, but I much prefer BG 44k. Just seems like a notable difference in feel and gas mileage after its use. And yes I use top tier fuel only.

Sea Foam will clean about ANYTHING! I put it in my gas tank, a little in the oil and run it through my brake booster vacuum line about once a year, but this will cause a misfire and trigger your check engine light. Just go to Autozone or some place similar and have it reset.

Not yet. Funny thing is that I got a check engine light yesterday and now I have to take to the dealer to see what it is. And now that I see this post again I wouldn't be surprised if it has something to do with the plugs. I hope so because anything else on my car isn't cheap.

For your Audi, according to the online maintenance schedule, your spark plugs should be "replaced at 35,000 miles or 3 years, whichever occurs first. Then, every 40,000 miles or 3 years, whichever occurs first." I'm guessing, based on the year of your car that it's close to 100K, so it may be time for a tune up?

So, if you're running a little rough and mileage is dipping, I'd look to replace the plugs AND your coil packs. I used to have an A4 and I had a rough idle and a couple of the coil packs needed to be replaced. Not cheap for the parts, but you can do it if you have a socket wrench and extension to save on labor. Take a peek at one of the Audi forums, I'm sue you'll find the exact info you need.

As far as answering your original question: if you pour the whole can of Seafoam into your gas tank, it will not blow up your engine or make it die. Follow the directions on the can and you'll be fine. Just don't expect it to fix it if you need scheduled maintenance.

Actually Ac, it only has about 26,000 miles on it the only things I have replaced were the belt the brakes and the windshield wipers

Wow! That's really low miles. Lucky guy. That car needs to be driven. You probably have some sediment in the fuel tank from the car sitting & not being driven frequently. The seafoam could help a little. Won't know till you give it a try. Even though the miles are low, I'd still have it looked at by an honest mechanic you know or a solid one who comes highly recommended. Due to age and not miles driven, you could have some dry rot on a vacuum hose somewhere or some minor corrosion on one of the coil packs. I'd take it to someone who knows these cars through-and-through and pay him for a thorough inspection to get a check list of maintenance items that need to be taken care of now or in the near future.

And since this is a detailing forum I suggest cleaning up your engine bay (if you haven't already). Take a look at this: http://www.autogeekonline.net/forum/...fessional.html

Your mechanic will thank you.
