I am not sure, but what you did will probably be fine. I know after my seafoam treatment my gas mileage raised from an average of 25 mpg or so to about 32 mpg. Still kind of low, but hopefully after I get around to changing the fuel filter it will be closer to 35-40.

Yeah, you guys have it right! The piston soak I like to leave it over night, you know, really give it a chance to work into that carbon. The reason I recommend the oil change after a soak is that I find most guys simply can't or won't make the effort to measure out a 1/2 oz. per cylinder.
You know who you are! The same guys who think "hey, they're sayin 45 min at 350 degrees here, who's got that kind of time? How about 700 degrees for 15 min"?
Or you can hear them in the grocery store askin "where do you keep the toast".
Hate to see someone spin a bearing because of excess sea foam running past those rings and into the crankcase.

Those mileage numbers really make the shelling out of $7 a can for that stuff come back quickly huh! How did you like the way the car idled after that?

Definitely worth it with those gas mileage rises, especially for a teen when nobody is hiring, lol! Also, the difference in the smoothness of the idle was like night and day. The car used to shake wildly when idling and now it is perfectly smooth and quiet.

Ok I just did the piston soak its almost 1230 am here, left it over night, just added 1/4 oz per cilinder to be safe since im not planning in changing my oil for a while since its almost new. Ill let you know how it cranks in the morning. Hope it does lol. Doing the sucking, soaking and gas treatment would it cure a morning ticking lifter? Guess I should add it to the crankcase for that but I really dont want to after reading what iceracerdude said. My engine is over 200.000 kms

Hi I did the sea foam treatment last evening left it sit for three hours. Who ever first suggested this I must say THANK YOU !!!!! All hesitation is gone the car runs smoother and has more power. The piston soak is scheduled for this week end Thanks Conard

Hi correct me if im wrong but If I did the piston soak shouldnt be kind of hard to start the car? It started better than ever today!!!!. Wonder if putting the seafoam into the sparkplug holes with a hot engine will dilute it pretty fast into the oilpan.

It did smoke a little bit under hard aceleration today though.

My benefits so far:
1- Flat spot while accelerating in lower rpms is gone!!!
2- Idles better (not perectly, I guess the car is just a bit rough on its idle)
3- When comming to a stop from any gear to neutral rpms would lower downa lot and then stabilize, thats gone too!!!!
4- More response for sure
5- I can swear that fuel economy improved just by seeing the fuel gauge being slower
6- Well as I said car started beautifully today, before I had to crank the starter a little bit more

I have left some seafoam which im going to use 1/3 on a 1/3 of the gas tank since im going to the seaside this weekend Ill apply it there. And the rest Ill do another sucking apply.

Seafoam is flammable so this may not be a good idea.

Hey guys, anyone know who sells this stuff so I can import some into Australia? I've got two old ratshit cars here which have suffered a life of neglect, they could use some seafoamin'

Ones the Egg, the other is a 2003 Mazda 323 which is pushing 300,000km, plus might use it on my newer cars as well to keep em fresh.

Thanks much.

I'm pretty sure seafoam has to be imported (you pay for shipping overseas) but I heard that subaru makes an "upper engine cleaner" that does pretty much the same thing, probably worth checking out to avoid the shipping charges for seafoam.

That's good, you've used it exactly the way it should be, even up to, and including your plans for the rest of the can! Just plan on doing a regular regiment of treatments and avoid the "hot engine concept".
Remember, you haven't done this to the car all along like alot of us do, so it's probably somewhat dirty still, so after you've got the car completely cleaned up (at least a couple more treatments) then see if it's reversed all of the problems. If you still have small issues then, that's when you can do some super fine tuning and really get the thing dialed in to knock down those great mileage numbers near the 40's.
Keep us posted on your progress, we love hearing success stories, and it's very helpful for guys trying to get the most from their cars.

It seems no one wants to ship it overseas, I think because its considered "dangerous goods" because its flammable.

I've gotta make a trip down to a Subaru dealership to get some upper engine cleaner, its an aerosol though, reckon it would be OK to do the piston soak with?

I've gotta do the oil, filter and plugs on the egg anyways, so I might as well as give her a piston soak, right?

There's a thread going on right now over at Festy.com where a guy's describing how bad his piston rings where stuck. I mean he's got the block torn down and the pistons out of the car and the rings were a real bugger to get loose from those pistons!
I've turned him on to "Dawn Power Dissolver" which he's been using on all of the cleanup process to dissolve a lot of the baked on carbon buildup.
To bad he wasn't doing these piston soaks all along, a lot of what he's experiencing right now could have been avoided.
I don't have any dirty pistons to show you guys right now, but I can tell you they sure work a lot better when the rings are able to float in the lands like they were designed to do. The piston soak will help dissolve that inevitable carbon buildup short of tearing the engine down.

I assume the "Dawn Power Dissolver" is the dishwashing liquid used in some manner to clean parts as they are disassembled?

I picked up 4 cans of this Subaru "Upper Engine Cleaner" today, cost me $80, going to give it a shot on our two dodgy cars, spray half the can in the inlet manifold vacuum hose while the car is at operating temperature but switched off, then let it sit for 5 minutes, then start the car and spray the other half in there while the car is running.

Should I also take the spark plugs out and spray it on top of the pistons or not with an aerosol like this, also how much would you suggest?

I just serviced the egg so I can't use it on that yet, maybe next service. During that service I did the oil, filter and plugs, all the plugs are burning grey/white which is good i think? But the 3rd spark plug, the ceramic was rusted/orange and the others were all fine?

Also a LOT of metal and sludge came out in the old oil and the lifters are very noisy, I have new ones but I just haven't been bothered to replace the old ones yet LOL.

Yeah she's knackered, it went 4 years without a service a while back, both my parents totally destroyed their cars, so i basically use them for experiments now, lol.

Its also developed an odd idle, when its cold it'll pick up revs like usual, but if you go to drive it, then come to a stop, it'll hang around 1500rpm then slowly drop down to idle.

The idle differences between "warmed up" and "cold" is usually a sign it's time for a new oxy sensor.
That metal in the pan you're seeing sounds like you may be losing the bearings!
This car may be FUBAH...and by the way, you never want to hear a nurse say that to another nurse about you if you're in an E.R.!
