Default the ultimate seafoam clean out?

Ok I have a few questions about seafoam here.

As far as I know, you can use it in your oil to clean out your crankcase and oil passages, also removes moisture from the oil etc. It can be used in your gas tank to run through to clean your fuel system and can be used directly through a vacuum line into your intake.

Oil System:
Is this supposed to be added to the oil just before an oil change or can you run this for a full 3,000 miles? Which is best and which is recommended.

Fuel System:
If I remember correctly, on the seafoam website, it says you can use one bottle of seafoam for 8-19 gallons of fuel, now on a Bonneville, we have 18 gallon tanks, and on a full tank, this would mean you could use up to a bit more than 2 bottles in their highest recommended concentration. Now does anyone know if it would hurt to maybe put 3 in? How would the car run? I imagine this would clean the injectors quite well. Also, would it hurt to run it on every tank? So that no build up ever occurs? Or would that have negligible effects?

Vacuum Hose:
How often should you do this? Is it helpful to do the run, shut off, wait, run sequence more than once in one service?

These are my opinions...not based on facts.

I would only put it in the oil a day or so before an oil change.
Fuel.. no more than the one can if that'* the concentration they tell you is allowable and there'* no need to do it all the time unless you are running varnish through them.
Top end cleaning.. once a year should be sufficient

I put it in the oil about 100 miles before an oil change, mind you thats about a week for me. And I only do that once every few years.

The top end cleaning I do when I get the car usually and then I won't do it again for a two or three years. If you do this, its going to smoke like... I do mine in the middle of the night when no one is around to even notice.

I do add it to the gas once a year. Fuel in NY is usually pretty clean.

Because most of the fuel sold in up state NY comes from CANADA.. lol

heres a secret Ultra 93 is really ultra 94 but because of branding it isnt sold like that. Also upper VT gets most of the Canadian fuel exported out of Quebec and Ontario.

Seafoam is awesome. I've never put it in my oil or gas, but I did the vacuum tube thing twice in one year. It didn't seem necessary, but it did clear up the engine nicely. It seems to breathe better now.

I too was curious about Sea Foam, before joining this forum I'd never heard of the stuff. I looked for it, but could not find any so I e-mailed the company asking for the names of places in my area that sells it. (west coast of Canada) A company rep sent me a reply the next day with that info plus he sent the following that I found handy.

If you have a lot of KMS. Sea Foam in the oil will clean all the gum, varnish and dirt and you might hear a noise you never heard before as the gum varnish dirt hides noise at times. Put 4 OZ in the oil if under 150,000 KM. after 5 KM check the oil if dirty change the oil if clean no problem do not change the oil. If the trans fluid is up to manufactures level put 3 oz in and you do not have to change and do not worry about over filling as part of the 3 oz will dissipate. Trans Tune will clean the valves, valve body and bands converter up. The brake booster is the best way so here goes For a gas (not diesel) fuel injected car, warm up the car and make sure

it is outside as there will be a lot of smoke during and after the

application.

With the car running at running temp, lift the hood and take the brake

vacuum line off the brake booster which is located on the fire wall

driver side. Pour slowly ½ can of SF-16 down the line this will melt

the varnish that holds the carbon at the back of the intake valves and

top of the pistons, you might have to turn up the RPM’* a bit so the

car will not stall.. After ½ can down the line shut the engine off and

put the line back on the booster let the unit sit for 10 minutes. Pour

the balance into the gas tank this will lubricate the fuel pump remove

moisture and clean the lines, filter and the injectors. The injectors are not too bad these days.

Now the show! Start the car and find a safe place from

a stop nail the gas peddle for about 100 yards, slow down and stop do

it again the smoke will be gone after 1KM I need the pressure (fast) to

get rid of the carbon.

You will notice a better idle, better fuel economy and more power. Did

you know that Sea foam will stabilize fuel for over 2 years, and works

in all 2,

4 stroke and diesel engines?



He also sent a pdf file with the official directions and uses for all the sea foam products. I can forward this file if anyone wants it.

don't want to hijack your thread here john, but i thought since this is a seafom thread, i'll post this question here...

how exactly do you put seafom into the vacuum lines? Any one have a picture of where you put it?

When I did my L27, I used the vac nipple that controls the trans modulator. Just plugged in a lenght of hose to it, stuck it in the can, and let it suck it down.

On the L67, I think I went with the BCA port. Wouldn't do it on 94-up L67s that way because of the rotor coating though.
