how bad is your compression?

The best method of testing ring condition is with a leak down tester or a blowby meter. As the cylinder wall wears the ring end gaps open up by a factor of pi. Nothing that you pour out of a can is going to correct that condition. If you at all serious about gaining fuel economy put in a set of Total Seal gapless rings. With proper cylinder bore prep you can achieve near 100% seal. More power also.

I have found from experience that good ol mystery oil can cover the symptoms of low compression and a failing engine.

You will be stuck using it in every tank of fuel though (doesn't work at all in oil) and god only knows what damage you will be incuring in the mean time.

Please dear god do not use Seafoam or any of that additive crap. Like someone said earlier, the "carbon" could be holding something together you don't want unstuck.

Yes, that's right, IT CAN BREAK YOUR CAR. Read the reviews on amazon. I looked into it but for every 10 positive reviews (backed by unquantified results), there was one person who's car ran like sh*t afterwards.

Does anyone have some verifiable tests they can share aside from opinion? Might have to make an account over at B.O.G. if I can't get some more credible answers... arg!

Although I know very little about the maintenance and care of cars in general, I think we're going to need more information.

What are the quantifiable symptoms you're having?

Also, you have a car that's almost 30 years old (if we're discussing the integra listed on your profile). If you're getting a rough idle, that might just be how it is after 29 years. Older, asian cars will do that. (And honestly cars in general)

Credible answers come from compitent questions, and compitent effort...

Do a compression check. It will take a compitent person less time then you've spent reading the three pages of this thread.

If the engine your talking about is a b-series (guessing by the teg in your garage), it's likely rings or HG, as those are usually the first to go.

There is no perminent solution in a can.

I am an avid believer in seafoam and ZDDPlus for preventitive maintenance and recovery due to a lack of, but in no way will they fix worn rings, out of round cylinders, blown/warped head/gaskets etc.

Sounds mean, but very true. I've read all of your (Jackal) posts on this thread and I can't figure out what the hell the problem is!

Since everyone just loves this seafoam, here are some reviews on amazon that say otherwise:

Amazon.com: Customer Reviews: Sea Foam Motor Tune - Up

Amazon.com: Customer Reviews: Sea Foam Motor Tune - Up

I know that MOST of them are positive, but is it really worth the risk of breaking your car?

I don't think you want credible answers I think you want to us to say something you want to hear. I was hoping I could save you time and money but you can only lead a horse to water. You can't make him drink.

Sorry I will not vouch for a product unless it actually works. Of the many many many products I have tried over the years not one will permanently help a worn out or hurt engine with low compression. I know this because I have owned vehicles with worn out engines and one that was very hurt (turned out to be a main bearing had spun)

Yes!... If you know what you are doing, and have a spare engine sitting on standby!
