Default Sea foam

Trying to find an existing thread on this but no luck. I'm thinking it may be worth throwing this in the tank. For the last 9 plus years I've only used regular 8 or 9 times. Is it a waste of money to use sea foam? Does using premium vs regular gas really make a difference in these motors?

Someone educate me please!

I've used sea foam twice in my G. I believe in it. Premium does make a difference. Don't use less than 91 in a G.

using less than 91 octane could reslut in detonation in our motors AKA boom!! not worth the couple dollars you save each fillup. unless you dont mind buying a new engine. using low test probably voids any engine replacement warranty as well

Thanks fellas. What do I do just throw a bottle or container of Sea Foam in when filling up the car? Have you guys ever thrown it in when doing an oil change? I just switched over to Synthetic.

Yes you can throw in 1/3-1/2 a bottle in gas tank....the biggest difference, to me, is the vaccum method (brake boost line) ..type in USING SEAFOAM in a google search, and see what you come up with.

the computer should detect and prevent and major issues, in doing so performance will be compromised.


there are countless people that have run 87 for years and had no issues. they just didn't get full performance

Thanks man - I did what you suggested. I found a link through another forum that led me to a nice written explanation. I'll pick up 2 cans this afternoon......Luckily I have new plugs to put in...

Sounds good...It's a rather fun process too. Just don't expect to turn a mutt into a thoroughbred...It'll help, but not usually day and night difference, but this also depends on many variables.

Got it. To be honest my engine runs fantastic, there is no hesitation. She can be a little rough at idle but there could be a few reasons for that. I'm gonna start off with throwing one can in the gas tank when I only have 8-10 gallons in there followed by 1/2 a can in the oil when I am a few miles out from having it changed.

Not sure if I wanna use it through the booster line though. What do you think?

The brake booster is the best part. In the oil however, is a little sketchy.

no clue, I just know there have been numerous people post on here that they have had no issue with 87 octane.

On your O.P. I couldn't tell if you were wanting a boost in octane or what the Seafoam is used for to correct in your case. It won't hurt at all to run it in your tank and it may help injectors. It's easy to get condensation in gas and it helps that too.

I would not use it as an oil additive nor would I recommend it - or anything else for that matter. Oil has a number of important things to do and it does it all pretty well. Synthetic has some advantages and will live longer maintaining viscosity and if the filtration system is optimum, you could run Syn for a long, long time. A case can easily be made that synthetic cost would be a wash since you can easily run it 6000 - 7000 miles if the filter is doing it's job or were to be swapped out around 3500 miles but most people are not as concerned of a few bucks more a year in oil changes. They are looking at the protective benefit and peace of mind.

Changing the properties of motor oil in my engine, especially the more expensive synthetic, by adding a chemical and essentially changing the viscosity even slightly, is not something I'd ever leave to chance.
Just my .02 cents ...

I would think solvent in the oil would be adverse to the protection it provides.

That's a pretty succinct statement -- bravo !

Also, (read elsewhere) I'd not be one to test brake cleaner on my car paint.
