Anybody ever put sea-foam into oil?

Sea Foam Question

Indy, in a 2 or 4 stroke? In a 2 stroke, with oil injection it'd be scary since you would dilute the oil and possibly seize your motor-adding it to gas gets it to the same place in a 2 stroke without the risk of thinning the oil. In a 4 stroke it would be used as a solvent to clean the internal components and probably be used to flush and replace with fresh oil vs run as an additive. My .02. You get what you pay for!!

When I see anything going into a oil tank (or gas tank) that isn't oil (or gas) I always panic just a little bit.

I have always been a firm believer that if all your preventative maintenance is done properly and you watch what you put in the tanks in the first place there should never be a need for any "fixes" in a can.

I know sometimes the gas you buy from a local bar that has a 55 gallon barrel out back may make people a little nervous so I just plan ahead and stay away from those. If you pump a bunch of water in your tank, or old crappy gas, all the additives in the world probably won't help at that point anyway.

Sea Foam is good stuff but only in gas. No way put in any crank case as will dilute oil erode seals & who knows what to internal parts. I learned not to put additives in oil as a kid to try & keep my POS cars going just does not help & causes more problems. Better off finding another engine at junk yard & drop that in easy quick & cheap for POS cars. Sleds only in gas.

ok thanks for the reply's, that's what i figured, i thought the can was a little crazy but just thought i'd ask if anybody tried it. I didn't plan on trying it, just wondering was the deal was with it.

Putting seafoam in the oil in a car with noisey valve train can many times quiet it right down since it really cleans passages quickly and frees sticky lifters.

I see no advantage adding it to oil in oil injected motors but can shakers, yes.

I have never put it in snowmobile oil however contrary to all the posts I use it frequently in my stand up jetskis when I sink them or fill the motor compartment up with water. In fact I have fogged the motor with it, dumped straight down the plug holes & straight into the carbs thru the reeds and into the case. It is an excellent decarbonizer, the trick on jet ski's is to get it started heat up the motor and get it hot and running immediately to eliminate the water. I have had the cases filled with water and the motor hydro-locked. It has saved my bacon a couple of times a year, both motors are modded out, big carbs, pipes, high comp heads, and has never once caused me problems. If you want to clean the carbon out , if that is what your after , dump it in the carbs ( outside your parents garage) and let it do it's thing. keep revving it until the SF is burned up . It will smoke the heck out of your neighborhood. It will peel the carbon right off the pistons, plugs everything. Just get your motor hot and flush out the SF then keep running your gas & oil through it. I'm not standing behind or promoting their product but I have never had a bad experience with it. this is not intended to offend others members opinions.

I dump about a cup full in my vehicles right before an oil change. I usually dump it in the moring, drive to work and back and then change the oil. You should see how black it comes out even after only 3-5 thousand miles.

On all my other engines I just use it in the gas.

X2 on quieting the lifters. Had an old Ford where the ticking would drive you insane.

I've got a buddy that does the same thing to his '90's era Chev pickup. The thing has about 300000 miles on it so I don't think he is doing it any harm. I will agree with the other posters in that I don't think it would be a very good idea to continually run Sea Foam in the engine oil.

I agree with madddog, I add it just before an oil change for about a day or two. I do it in all my vehicles.

What is sea foam? Is it a Sea and snow additive? lol, No really is that stuff like Stabil? Everyone trying to reinvent the program. Pissed cause their sled blows up. Get real. Follow the directions for your sled. Does it say anywhere to do this. My sleds are beaten hard and stay together. Just follow the manual that comes with the sled. common sense. Not sure where the words "Sea or Foam" come into play with a snowmobile. Help me on this one. Sell it to me!

I think Indy means in your car or truck, not a snowmobile. I put some in each one of my vehicles right before I am about to change the oil. It does a great job of cleaning the crap out. Put it in, drive to work, drive home from work, and change the oil.

What is Sea Foam? I have never seen it any where in my area. What kinda crap out? I use Amsoil (duh) with the Amsoil filter in all my vehicles and change every 15,000 miles if it needs it or not. What crap? what junk are we flushing out? When I used pensoil I had huge parafin wax issues from that oil in a 350 Camaro. Is that the crap you speak of? or is it other stuff?

I believe the crap is carbon deposits. It consists of 1 petroleum distillates and 1 petroleum oil and #2 proponal which is alcohol . I looked these up a couple of years ago and they are seperate items that can be bought. It's just another snake oil out on the market but it does work. Better yet if you have stand up jet ski's it's a must / motor saver when you " sub " them and or hydro lock your motor. I know you have it in your area somewhere, the local " tractor supply" or auto parts store. I have several snake oils on the shelf, stabil, stabil Marine, starTron, seafoam.... even have some bottles of dry gas ( ISO ) that keep getting in my way, havent used them for years. Maybe I'll go out and burn leaves with them.

Some are addicted to using this stuff all the time. Maybe if you have problems but regular use only benefits the maker of the product.

Use quality fuel and good oil and you will never need it. I have never used it.

Many years back we had an old 70's Onan generator at work. It had starting problems and was tough to start but eventually would. So a co-worker put this stuff in the fuel tank one day and we ran all one day and it never would ever start again. The mechanic shop worked on it and finally told us to buy a new generator and send this Onan to auction. Maybe just coincidence but he did get blamed for ruining the engine, albeit ribbing. He took so much heat for it that he would not touch the new generator.

some food for thought ,guys. if you were to take the oil fill cap or valve cover off an older engine you will see a sludge that has adhered itself over time! note i said adhered! if you were to use ANY flush or cleaner,now you break this stuff loose and the filter will help, but does it catch all? A motor has not only tight tolerences but lifters can trap this crap! I believe if you use a flush from the beginning of an engines life, it will stay clean = no problems. but to start AFTER sludge has built up, could cause probs! if its stuck or adhered, leave it! just my opinion guys , hope it helps
