I'm changing my oil today, and I seem to remember someone adding Seafoam to the new oil.
Is this ok to do?
Thanks!

Is there a symptom you are trying to address?

No; just trying to keep the engine clean and trouble free.

It depends on the condition of your engine.. If its a pretty fresh engine, like you had a full, or even partial rebuild, and your seals and gaskets are all fairly new and oil pan relatively fresh, then id say sure, sea foam it if you want to keep it clean..

But if your engine is original, old seals, and gaskets, then i wouldn't.. Sea Foam will clean an old engine out, but it might do it a little to well, and you might end up moving sludge chunks and clog lines, or open up leaks in your gaskets and seals.

If your engine is running good, then just change your oil and oil filter.. If you want to put a little Sea Foam in your gas to clean your injectors and such, go ahead, just be sure to read how much to add to your gas.. But you can easily do that with some STP gas treatment you can find at any gas station for like $1.25.. I put one in every time i fill my tank.

Sea Foam is a good product, but isnt the best thing for 23+ year old engines.

I have used Rislone in the past, very good product, been around for years. It will keep engines clean, quiets lifters, maintains viscosity and help remove engine sludge and deposits over time.

I've told the story here on the forum of an old Plymouth Duster that had lifter tick so bad you could hear it echo off of nearby buildings. After 2000 miles, Rislone really quieted it down. It's good stuff and I would use it in the crankcase instead of the seafoam. Seafoam does work excellent in the intake and gas lines though.

Seafoam is for cleaning. Used in the old oil about 50-100 miles before you want to change it. I would never ever use it in new oil unless you plan on changing it again in 100 miles. (BTW - a pint of auto trans fluid cleans very well before an oil change )

I use Engine Break-In Oil Additive - TB Zinc Plus from Lucas. http://www.lucasoil.com/pro...=82&catid=9&loc=show With the removal of zinc from motor oils this adds the zinc back into the oil to protect the cam and lifters on our flat tappet motors.

I agree with Hudini. I'd use it shortly before changing the oil if you feel a need to de-sludge the motor. I wouldn't use it as a long term deal. Actually, changing your oil on a regular basis should keep it adequately clean without using additives.
