STP came out with a very similar product (STP Multipurpose Motor Treatment). This product is advertised to do the same thing, but does not have alcohol in it. I saw it is usually a couple of bucks cheaper, so I bought two cans. Ill have to post if it works the same.
I just seafoamed my 2001 Suburban LT with 160k. Before the seafoam, my truck was running a little rough and was pinging on acceleration around 1800-2000 rpm. I use the power brake vacuum to suck down 1/2 a can of seafoam until the engine stalled. The truck sat for twenty minutes ( btw, the truck was at normal operating temp). Once i started the truck tons of smoke poured from the exhaust. I got on the highway and gunned the engine and lots of white and black smoke pour out the back. When i got home the engine would idle super quiet. As I drove the truck it seem to get better. I keep records on fuel/ mileage. I went from 12 mpg the 14.9 mpg in two tanks. Seafoam seems to have worked for me.
I'm scared of Seafoam after seeing cars hydro-lock or in those cases where the carbon and sludge got lose and created oil leaks! I used some on my typical lawn-mower from walmart and it roared back to life with more power than ever after smoking like a mofo!
I'm really tempted to use this treatment...
The hydrolock happens when people suck to much in at a fast rate.
I would like to see a set of solid instructions for seafoaming through the intake... specifically on a 2000 5.3L engine. I went to their web site and it was really confusing....
You can seafoam through your intake manifold if you have this, this and that, but not this...... blah, blah, blah....... I don't want to damage my intake manifold.
I did it in my 02 5.3L thru the brake booster vacuum line. I just let it slowly suck it in. Then I shut the truck off and let it sit for an hour. It did diesel a little bit when I shut it off. I have seen posts that say slowly suck it in and then at the end let it suck in fast to kill the motor. I was also nervous about doing this. They way I did it seemed to work well. I was not worried about damaging the manifold as much as I was worried about hydro locking the motor. I doubt that 1/2 a can would be enough to hydro lock it though.
B12 Chemtool is WAAAAAAAAAAAAAy better everyone
and it comes in arosol
i was seafoam for 10 years.... what a huge waste of money =(
What do people don't have to brake booster? Mine uses the power steering so I can't run this through the vacuum lines.
