seafoam - does it do what it claims?

I love the stuff, and have been using it for years. It was originally marketed for marine applications (hence the name), but it works in any engine.

It's a little more expensive here, about $9 a pint.

I use a half can to a tank now and then to keep things clean. The proper way to do it is...

1. Pour it in the gas, and let the engine run enough to get it in the carb bowls.

2. Let it sit overnight, so it can do it's thing.

3. Run it like you stole it until most of the mixed fuel has run through, then add fresh gas.

4. Change spark plugs, as Seafoam tends to foul them out.
 
It works perfectly as a starting fluid on a two stroke chainsaw-just like the website says. Will let you know a mechanically sound motor that just isn't getting fuel.

Also, works perfectly when an engine is just beyond limits when doing smog on a motor. Gently pour a third of a can through the throttle body and will clean enough carbon off the pistons to pass.
 
So, on my 78 GS 750E, where do I put it in to get to the engine without taking the tank off and spark plugs? I already have some in the tank, fyi. Any hoses or anything?

FWIW, I heard somewhere the other day that Checker/O'Reilly is having a Buy 2 Get One Free "sale" on it. Haven't checked it out myself to verify yet.

Whoa, just watch those and some more on youtube and cannot believe how many people on there are filming their tailpipes! Too funny

Had a lawn mower that had sat 3 or so years. long enough that all the gas - evaporated!!?!. third of a can, and one can of gas. Works better than trying to work on a non-serviceable carb!
 
Greetings,
If you add sea foam to you oil as suggested will it cause leaks? I was new and was talked into synthetic oil now I have a base gasket leak. I just do not want any more leaks what do you all think.
Thanks

Nice tip, sure enough on page three of their online flyer buy 2 get one, limit 8 free:eek:!
Unfortunately, the drive out to their nearest store (to me) in Ohio would negate the savings :D
At least now I know what to look for and a price reference:)

I was never a believer of "don't use Synthetic, you'll get leaks" theory. I use it in all my cars and bikes, no more or less leaks than prior. I'm new to Seafoam but I'd think if you keep the concentration in check, you should be fine? Anyone else?

In the crankcase, you are only using it shortly before an oil change (I wouldn't use more than a couple tablespoons )....maybe putt around for a few easy miles and immediately drain the oil & change filter.
Both synthetic oil, and Seafoam (which is essentially acting as a solvent here) won't cause leaks, but won't do you any favors if you already have issues with compromised seals that are plugged up by gunk.
 
Seafoam is sold at every automotive chain, marine shop and most small engine places. I wasn't much of a believer in 'snake oils' but after enough customers came in to my automotive parts store swearing by it I tried it. Love the stuff, use it in my bike, cars and mower.
 
I just did a carb rebuild on an 82 GS650GL barn find. It ran OK, but I put Seafoam in it and it ran like it's ass was on fire! I use it in my small engines, and I swear by it.
 
Seafoam works wonders, but not miracles. I like it and use quite a bit.

I tried some Seafoam in the sailboat engine last week.
It is an old Atomic 4 from the 1960's.
It was burning a bit of oil when I go full reverse, stops my from hitting the harbour wall.
Put 2 oz. in the crankcase and 2 oz. in about 2 gallons of fuel, Ultra 94 from Sunoco.

I noticed an improvement.

Tried it in the bike this week.
Seems to be a happier bike after about 100KM.

Will change the oil soon.

Great Stuff! Use it all the time and in everything that runs on gasoline. I have used it in the crankcase after placing a call to the manufacturer because one of their reps wondered about its affect on the bonding agents on the friction material on the clutch plates..(something I never would have thought of). It is fine they determined, and i can attest that I have found no problems on several bikes. It will clean the internals very well. I also suck some up into the vacuum system and let it sit. Cleans that part very well too.
