What is this stuff?/ I've seen it referenced in other sites, but would like to know the opinions of this site's members. My Fletwood has 185,000 miles and my Eldorado had 105,000 and I'm wondering if this stuff will help clean out the cumbustion chambers.

That's exactly what it does. You pour in in. Stall the engine with it. Let it sit. You have be careful not to hydrolock the engine.

Let it sit couple of hours or overnight. Then start the car. Watch out...you will have pulms of smoke comming out of the tail pipe..carbon.

Good stuff for cleaning out carbon.

It's basically Seafoam which you can get at NAPA or Auto zone for about 7 bucks a can.

Last time i checked it was the same size bottle.(buy from autoadvance) BTW I only let it sit there for 15 mins, I don't know if it would be ok to leave there for couple of hours or overnight. Make sure you take out all of the seafoam. Here is My TC

If I put it in, say right before an emissions test; would that be a bad idea?

Allow a week of driving a week before inspection, just in case

A little tap water in a spray bottle will do anything the snake oils will do.

Yes, seafoam is sh@t. Like dkoz says, you'll get the same results with water.
