It cleans the varnish and sludge from your valve train, etc.I have read posts and seen DIY's on using Sea Foam to clean out your engine...
Is this a recomended/usefull practice?
How many do this? have done/tried this?
Does it actually work?
What are the benifits?
Is it harmless?
Sounds like a problem to me.i've used it. no problems. it confused the ECU for about a week.
A few responded with about a 50/50 split but I agree with you here.Doubt you'll get a consensus on this.
If there's a potential downside of creating a problem I'm a big believer in the axiom: If it ain't broke, don't fix it. I'm sure others will disagree, but that's my 2¢.
