I wouldn't put that stuff in the oil because I feel a bit uneasy putting in fluid that is thinner than the actual oil.

As for the vacuum line, it made a huge puff of smoke and it idles smoother and thats about it. I would pull the hose from the evap cannister since its a much bigger hose than the other lines and not as big as the brake booster line which I had a hard time pulling off..

I used the brake booster hose. Worked well...not as big of a cloud of smoke as I hoped but it did smooth out my idle.

Probably just throwing his money away. SeaFoam is great stuff, but once or twice a year is plenty.

Willwren is dead on about the Cat issue. I go through a LOT of cars in my
business and hobbie. After experimenting with Seafoam on more than
a few cars, The one problem I encountered was clogged cats after using
Seafoam over a period of several days. Not only does it clog a relatively
new cat, but it will kill a old cat in short order.

Seafoam does work well on carbon deposits in the chamber, but
the crap has to go somewhere as Willwren said, and that stops at the
converter.

Examples of Seafoam destruction :

1995 Taurus SHO -clogged both cats.

1984 Z-28 - clogged a 3in. cat so bad it broke in pieces.

1994 Z-28 - clogged cat bad enough to cause car to ping.
I had to remove.

1997 Z-28 - clogged both cats bad enough that car dropped
12 MPG. Removed both of them.

1995 Chrysler Minivan - Last straw. Clogged bad enough that van
would not run.

All of these vehicles were mine at one time or another. Seafoam
was used in fuel tank in proper amount specified on can.

All I can say is -Buyer/user beware.

you have to realize that an engine that is relatively clean will blow out less carbon.

If you plan on replacing the cat run some seafoam, what do you have to lose.
