Seafoam suggestion ?????
I'd like to use this product when I pull it out of hibernation in the spring (69 390 horse). My question is, is it worth it? If so, How do I use it? On a full tank? how much of the can do i use? Any suggestion would be appreciated.

I did the whole SeaFoam treatment on a Mazda with 173,000 miles on it and I was suprised at the results. I wasn't expecting much of anything, and the oil treatment didn't show much. The intake treatment produced an amazing amount of smoke when I drove the car. I don't know how much the gas treatment helped, but the engine has been running far better after the treatment than before. I don't think using SeaFoam will hurt your engine and it could possibly make it run better.

Works good for me too...
Suck a third of the bottle through a vacuum hose...let it stall. Let the car sit for 15 minutes, restart and watch the smoke show.

It will help to dislodge built up carbon deposits on your valves and in your combustion chamber, plus clean some fuel deposits off carb components (if you have any build-up). If you follow directions, it won't do any harm to the engine. Mike Ward is correct: if your engine is in 'tip-top' condition, it is unnecessary. Is your engine in 'tip-top' condition?

if you do a search for seafoam and scam in google you will get a lot of posts talking about how seafoam is chemically unable to dissolve carbon and that it is just a oil by product. the smoke is just the seafoam itself burning off. im no chemist but there are plenty of skeptics out there about cure alls.

My car was stored before I got it and the idel was just a tad shakey. Knowing everything was in great condition or new I just added a can to the tank and it smothed out completly. I have been driving the 78 everyday this past month and have gone through a few tanks of gas. It is runing very smooth.
I also put the SeaFoam in my wifes Cadillac and it cleared up a "Service Engine Soon" light within 25 miles of driving and the condition has not returned in more than 2 months of driving.

ive never tried it, everyone yells snake oil snake oil every time someone brings up oil addtives but seafoam im not convinced it is the miracle it is supposed to be.
i havent seen any positive proof just a lot of placebo affect here.
stuff like the engine seemed to run better isnt proof. its that same sort of thinking that leads people to say that their new 10 dollar spark plugs make more hp than the worn out ones they just took out.
call me a scientist. i would just rather see hard evidence on anything i believe in.
im the same way about politicians and religion

When I started up my Mazda after the SeaFoam treatment there wasn't any smoke coming out. I thought the whole claim was BS but when I put a load on the engine the smoke came out in clouds. It continued for ~15 minutes in diminishing quantities. Looking into the oil filler hole I can see that a lot of the brown deposits in the top end have been removed.
I may try the whole SeaFoam treatment on the Volvo. The transmission is getting ready to take a dump anyway so there isn't much to lose.

How does someone prove that something would have happened irrespective of whether the product was used or not?
"My car ran like crap one morning so I poured an ounce of zippyjuice into the gas. After a 200 mile round trip, it was running great. That proves it works."

i had a problem several years ago with mine. ran like crap and always dieseled when i shut it down.
poured half a bottle down the carb with the vacuum line, and dumped half in the oil. immediately stopped dieseling and ran much better. when i changed the oil, it was absolutely filthy. when i had the oil pan/valve covers off this last summer, things looked very clean in there.
of course with never seeing in the motor before, its hard to make a call if it did any good in there.

OK, how does someone prove that something does nothing?

In the case of my Mazda, I was experiencing surging at steady-state crusing and stumbling on acceleration. After using the SeaFoam, with no other changes, the surging ceased, the stumbling stopped and there was a noticeable increase in engine response. I have been driving this car since 1999 so I am very familiar with it. I don't really care whether others believe that SeaFoam will improve an engine's behavior. It isn't a "rebuild-in-a-can" and doesn't claim to be. My Mazda engine was very sludged-up from a lot of short trips over the last several years and the SeaFoam helped to clean out the accumulated sludge and made the engine run better. It's been a few months since the treatment and the engine is still running better.
