Seafoam Treatment

[NickLS]

DMcBride... You have a write up on doing this?

What changes did you notice in the performance of the car?? Increased MPG? Smoother Idle? Smoother/More powerful acceleration?

You should see all the smoke... I've used it about 4 times by sucking it into the intake through the booster line. Put about half the can in a shallow container, suck it up little by little into the line. The engine will want to die, then just take the line out of the fluid and let the engine rev back up. Repeat. When its almost gone keep the line in the fluid and let it kill the engine, or just turn the engine off at the end. Let the car sit for about 20 mins then start it up and rev the hell out of it. Take it for a spin and drive it hard. I would say my car idled more smoothly afterwards. This is on my Mark VIII though, couldn't tell you about the LS.

The 16oz can is what your talking about rmac?

So you'll want to suck up 8oz?

Yeah I usually do half the can. I don't have one now but 16 oz. sounds about right. You can either dump the other half in your gas tank or save it for another treatment. There are quite a few posts about the process in the Mark VIII section.
