Used the Seafoam yesterday. The car smoked a good bit and I drove it around the block and let it sit overnight. Today, the car definitely runs smoother and revs easier. I think I may actually see an MPG increase over my usual 19-20. I'll have to use it every other oil change for sure. Thanks guys.

Last two tanks have been about 2-3 MPH better
My first Seafoam/Oil change was right before that

I am interested in doing the Seafoam thing too. Did you add Seafoam in place of some of the oil, at what ratio, and for how long? I add it to my 2 stroke boat fuel and don't know the process with the Mustang. I'm not going to mess with the brake idea but will do the fuel and oil additions. Thanks for helping and posting.

Yeah. I put a third in my intake, a third in the oil, and a third in the gas. So 1/3 of a pint in six quarts would be roughly 1:36. That's one ounce of Seafoam of 36 ounces of oil. I know you probably didn't need to know all that but I like figuring out useless stuff and then quoting it. :gringreen

I need all the help I can get! So, it would be fine to add it to the proper oil level, rather than backing out any oil to accomodate the Seafoam. Doesn't sound like 1/3 or 1/2 can would hurt the level, just want to be sure. Thanks to you and stlwagon.

You actually want to add right BEFORE you change your oil, not during a change
Run the car for 0-100 miles after treatment and THEN do an oil change
This is important cause you do not want all that crap from the engine
dissolved in your engine oil for very long nowatimsayin

i only knew about putting it into the gas tank. I've heard a lot of ppl using it but i am hesitant to use it. I might need to try it out. Couldn't hurt to pour 1/2 a can into the gas tank right?

If most of us are running synthetic oil from almost day one, is there really any point in putting Seafoam in the crankcase. I'm thinking the only reason you would put Seafoam in the crankcase would be to remove any sludge that may of formed, but if we have been using synthetic oil, there should not be any sludge.

Am I off base on this one?

i always thought you just put half a can in your gas tank and thats it....

No, you pull the evap tube (#5) and attach a small hose to the intake plenum.
Hmm I don't know that I would be comfortable doing this. Since I've only had Full Synthetic Oil since 500 miles, I don't think I need this step. I'll stick with the gas and oil. I was thinking about doing this to my wife's camry because it just passed 84K miles, any ideas on where it goes in that?

I've done it too. It just smokes for a little while. If you could see what your plugs, CMC plates, and piston tops look like, you'd think differently. Putting it only in the gas tank would probably only lube up/clean your injectors.

??? Not sure I'm seeing the connection between synthetic oil and a dirty intake. :scratchchin

I think I may have mis posted now that I think about it. I guess I really don't understand the process of putting it in the intake if I can't just pour it in. It's probably one of those things that if somebody showed me in person I would be like OHHHH. Oh well, maybe I'll figure it out.

It's the small tube that goes into the intake manifold. Go start your car and pull it off. You'll feel alot of vacuum...it will slurp that stuff right up out of the can easily.

I have not put Seafoam into my Stang yet but I did put it into a 99 Mirage. I sucked it into the intake from the PCV tube and it immediately stopped the ticking sound that has been going on for the last 2 years. I also added it to the gas. I will try the crankcase method before my next oil change. I am gonna do the Mustang soon. The Mirage was my test mule. I tried 3 different additives to get rid of the ticking sound and only the Seafoam worked. Alot of smoked poured out the exhaust. I mean a neighbor came out to make sure I was OK. Im hoping that the Oil catch can I just installed on the Stang will help me not need to suck it into the intake.
