Seafoam Haters

I heard someone mention that there were quite a few Seafoam haters out there. I was considering doing it, not because my Jeep runs poorly but because I was hoping it would run a little better. Maybe even help the MPG's. I've heard why I should so I want to hear from the haters why I shouldn't. Is it a risky and why?

From what I gather:

1) it can dislodge deposits that keep your jeep from leaking.
2) it adds more gunk on the intake ports
3) this is something I've wondered myself, does it ruin your cat by having all the burnt up stuff flow down through it?

Run enough seafoam and it'll clear out everything. It'll clean out your gas tank, then your fuel filter, then your lines, then your injector, then your intake, then your exhaust.

People like to over-react over thingsl ike this because it's unfamiliar to it. It's been proven to work. It breaks down the gunk and basically disssolves it into microscopic particles that won't clog up anything.

I've been thinking of running a few tanks with it for the same reasons as the OP, just to clean everything up internally so I know it's as good as it can be.

These are the facts... Seafoam works. Whether you pour it in your fuel tank, add it to the oil, or inject it thru the vac system... It works to clean out fuel varnish and baked or caked on oil in your engine. It doesn't cause new problems, but can reveal existing issues that were masked be all the gunk.

I have used it in my diesels on my boat, in my oil on the boat, in my gas and oil on my motorcycles and on my jeepfluids as well... if it "hurts" things I havent seen it for years, i believe it helps, but my opinion is in NO WAY scentific prrof of its effectiveness... BUT, i will keep using it for sure!

Don't forget to use the Seafoam Deep Creep to clean the throttle body. Spray down the interior of the TB and give it a good scrub with an old toothbrush. FYI...Don't use your wifes toothbrush, she won't be happy. LOL. Seriously, about once a year, I pour about a of the can down the brake hose vacuum line til it chokes down. I then clean the TB and restart the engine. Engine runs great and the insides are clean as a whistle. I know, I checked it with my snake camera.

Wow. So far, mostly only positive responses. So far all the negative comments have basically been a bunch of (maybe's and possible's). Does anyone have a true "horror" story about the stuff? Thanks guys for all the responses.

Well, I can say I used a can once and it did nothing to improve how the rig ran.

Never used it in the crankcase, but I need to now, think I have a stuck lifter in the Mustang.

I think the only reason folks may have trouble is if there is so much gunk that it breaks it up then it clogs the intake screen on the oil pump. In which its not the cleaner but all the crap thats in there that causes the issues.

I love the stuff no complaints and in the crankcase it will fix the lifter and everything else in your motor the only horror I have with it is that it's almost 9$ a can

Yeah, Im hoping stuck and not collapsed... and still assuming its the lifter.

Right now I just added some ATF to get things started; payday will be the seafoam.

Well I don't have horror stories of it messing anything up. I've used it in everything I run, noticed the other day that the jeep had a small tick from the lifters. Put a bottle in the oil ran it for a week and changed the oil no tick anymore, actualy in the first hour of running it the tick went away. I run a bottle threw the break vacuum line once a year also just pull it of and let the vacuum suck it up till it Boggs down. She will smoke like a freight train but it does help.

CB12 does the same from what I have seen. I use them both 1/3 can through a vacuum line in the intake, and the rest of the can in the gas tank. This works to clear a rough idle 90% of the time

I've used it in Jeeps, Dirtbikes, Streetbikes and Hot Rods. It's one of the few additives out there that actually seems to do something besides lighten you wallet. I've seen very good reviews of it on several different forums.

only horror story I have is that when putting the Seafoam through my vac line, the PVC elbow dealio burnt off and squirted oil all over myself and the engine bay. Just put a new one on and runs fine afterwards. Other would be it cost $9 a can AND it pisses off other patrons or neighbors when the white plume comes towards their open windowed cars or houses :]

It was my aanswer to a failed smog after running reaal rich for a short period of time. I had a bad pressure regulator on a 2.5 TBI. So fixed the pressure regulator and a tank of seafoam. Passed with very low readings and cleaned up everything aall the way into the exhaust pipe. Love it run regular now.

That is one of its major purposes. Fixed mine.

I love the stuff, have a can in my tank right now, about 1/4 of the tank used up, already steadied out the rough idle I had with it.

Just used seafoam for the first time ever in my tank.
WOW

So far I've noticed.
1. Smoother cruising
2. Valve clicking gone
3. Smoother low end
4. More low end power
5. More mpg. (Not calculated)
6. Starts easier and runs as if I put new injectors in it

Hi All, I have used Seafoam in the past for my boat and other motors, however never an automobile.

I used it today on my sons 1991 / 2.5 with 125K on the clock. He picked this Jeep up over the summer and I have been doing some mechanical upgrades over the past month or so.

I added a can to the gas tank and then added 1/2 can to the vacuum hose off the brake booster as directed here and other places.

As the directions called, I poured the Seafoam into the hose at a very slow rate with my son keeping the motor at 1800-2000 RPMs. Toward the end of the pour, we got the heavy white smoke....once it was in, cut the engine and waited 15 mins. When we started it up again, I was expecting allot of white smoke, however it was not that heavy....as he took off up the road, I could see it however.

So far, it seems to have worked....we didn't have any major issues, however thought it could run smoother. We should have a better feel in a day or two.

Mike
