Are you going to suck it in a vacuum line, or do it in the gas.

Looks like he'* talking about putting it in the oil.

Personally, I'd advise against putting it in the oil (I bet it wouldn't get along with the bearings very well). Get the Gm stuff like Roque suggested. I think that'* what I'll be picking up Friday and putting in before my oil change Sunday.

I've used Sea Foam in the oil before without any ill effects, there have been a few puffs of smoke from some crap being burned off. And it says on the can that it wont damage O2 sensors, at least mine arent bad since I pull in around 300 miles to 3/4 tank of gas.

oil doesnt go in the cylinders or the valve chambers so how does the seafoam clean those?

Very true. I can't believe I wasn't thinking from that standpoint. I guess, I need to really 'look outside the box' more often.

So if I do put it in the oil, I shouldn't drive it; just put it in and let it run for a couple minutes and then do the oil change. I'm wondering if it would even do anything like Rague said, oil doesn't go in the cylinders. I'm thinking I should just put it in the gas.

So you can put sea foam nearly anywhere?

Well, just to let you know it didn't really do anything. I drove it 10 miles before I changed the oil, and when I changed it, it was still clean.

all that putting it in the oil will do is maybe clean the oil passages. You want that stuff going where the power is made (manifolds, cylinders, etc) TRy putting it in the gas or a vacuum line.

what one is the vacuum line?
