I let it sip the sea foam through the PCV valve. You dont want it taking too much at a time though, if it inhales too much it will drown out. You'll be able to tell if your giving it too much or not. I did that once and it seemed to help, although i had a little trouble starting it a few minutes after adding it, probably not related to the seafoam though. Id definitely recommend it, as well as the Lucas fuel injector cleaner.
