So I decided to run some SeaFoam into my engine even though it only has 34,000 miles on it. I figured I would do it before the warranty ran out in case it knocked some crap loose and gave me problems. Also, I figured it would be a good idea to do it now since I drive it pretty hard most of the time.

Anyway, I used the vacuum hose from the brake booster to slowly suck up about 1/3 of a can of SeaFoam. Then I replaced the hose and turned off my car. About 10 minutes later I started it up and revved it for a while and it smoked pretty good for about 2 minutes. Then I went and drove it hard for about 10 minutes.

Results:

It honestly seems to run better now. Seems like it revs a little smoother and MIGHT even seem slightly more powerful. I also think it sounds a little better; but that could just be my imagination... I dunno.

I definitely recommend it! I plan on keeping my G for a long time and I feel like I just added to its life by cleaning the engine some. Good preventative maintenance, if you ask me.

 

I have seafoamed many cars with great results. I have since started using BG Throttle Body and Intake Cleaner. IMO it does a much better job at cleaning all that gunk out.

 

ya, i just had a fuel injector cleaning done myself, had the nissan dealership do it because they had a special on it. They also gave me a fuel system dryer and a can of fuel injector cleaner/octane booster. it was by a company called BG or something

I honestly didn't really notice to much of a difference. But i just got my car and its like -10 right now, so i have no idea how much effect it has, i did it as a maintenance thing, i will probably have it done again in like 20K miles or about 2-3 years.

 

I did this on mine, with similar mileage and it worked like a charm as well!

Out of curiosity, did you do the "deep creep" into the throttle body as well?

 

Hm. Interesting. What exactly does seafoam do?

 

I've been curious about doin this for a while now... can you post a flick of the line you fed the seafoam through?

 

Here you go...


Wouldn't embed

 

thanks!

 

I found this guys video very explanatory


The only thing that puzzles me is the fuel tank application.

In few other videos they constantly mention that if you put it in oil, make sure you do the oil change right after. What about fuel. How much fuel do you have to have in the tank when you put seafom in it?

 

What I did was just pour a whole can into a full tank and then didn't fill up again until most of the tank was gone. I read this was the best way to do it and I had no problems.

 

did you do the oil and vac line after you did the fuel tank, before or during?

 

i got about 86,000 miles on 06 G35 coupe..

1. does seafoam hurt the engine?
2. any risks?
3. with 86k will it be safe to do this?

 

I did it all at the same time. Half a can into the oil, half a can into the vac line and a whole can into the gas tank.

This is the DIY I followed as it seemed to be the most comprehensive one I found.

The only thing I didn't do is the throttle body, because I didn't understand where the "fan blades" are in the throttle body.

 

I read a lot about seafoaming and I didn't see anything about risks. The only thing people warned against is that if you do it too often, you may ruin your plugs.

With an 86K mile engine, I would definitely recommend it. I had 34K and it blacked out the sky.

 

nice, ill be trying this tomorrow
i already put some redline fuel systems cleaner in my gas tank so I'll just be putting it in the vac line from my brake booster.

i'll let you guys know how it goes

BTW i have 50k on my 03 sedan
i wonder how much buildup there could possibly be?
