Seafoam anyone?

Has anyone here actually use it just by throwing it in the gas tank?

Do you have to fill up the tank once you put it in or do you just drive around with it then fill up whenever?

Will it work just as well if you dilute it (putting it in a full tank) as if you are not diluting it as much (putting it in when you're near empty)?

I'm not quite at the point that I think it'll benefit the G6 yet, HOWEVER the fiancee's car is another story.

I sometimes put it in about half tank so it will work stronger, however with that much treatment, you risk breaking down the gunk in the fuel filter to run through to your injectors.

i believe that sea foam is probably one of the best products i have used. i used it on a 76 chevelle, and it looked like a freaking head gasket blew! but could actually feel a better idle immediately. good stuff!

I think you do it with a full tank.

I decided to use it on my fiancee's car as a guinea pig since her car is a POS (2005 Dodge Neon SXT) and it really didn't do too much to it. Still runs about the same way, no smoke screen , still runs like a pig; but that was just throwing it in the tank with about 1/4 left in the tank. If I would actually grown a brain and put it directely into the engine might've had better results.

I have not used Seafoam on the G6 yet. However, I do have a lot of experience using it on my previous car, a 1995 Saturn SW2. As ya'll've probably heard saturns tend to drink/burn a lot of oil. Using Seafoam directly in the intake was great for cleaning out the top end of the engine and the intake manifold, I also added it to the fuel, about one can per full tank (12 gallons of gas) a simple procedure, pour in seafoam, add gas, done.

One time when it was being a real pig and eating a ton of oil I waited until I was about to change the oil and added about 1/2 a can directly to the engine oil. I ran the car for about 70 miles with seafoam in the oil and then changed the oil. The consumption went from about 3 quarts per oil change to 1. So yeah, it works. I can't really speak to it's effects on longevity except to note that when I wrecked the saturn (70 MPH spin to smash into guard rail on Route 68 in West Virginia) the car had almost 160000 miles and ran like a champ.

I used to really like fogging the mosquitoes in the summer time. The procedure was really easy on the saturn, simply suck up seafoam using the pcv valve while goosing the throttle to keep it running. Then watch as the fog comes rolling out the exhaust! It will work with water as well, but the seafoam really does a nice job of degreasing the top of the engine/valves etc...

I think that when I do the oil change on the G6 I may put a can in with a full tank of gas just to clean out the injectors a bit.

my dad's chevy 1600 was having sputtering problems, an advance auto parts employee told me pour half in the tank and to stick the vacuum hose in the can and let it suck the rest of it dry. i dont know if it worked (it turned out to be a cracked block) but it sure was impressive.

Did It.

I poured a whole can of Seafoam in the last tank of gas. I'm about halfway through the tank and the engine seems a lot smoother, it doesn't really feel a lot "stronger" but it does feel like it's running cleaner. I can now chirp tire when using the autostick to shift to second so maybe it is running a bit stronger?

wow forgot all about my old old thread. Mine's been doing the rough idling even though I'm using the tier one gas they love so much so it's either getting sea foamed or going to get the injectors cleaned next oil change.

Best way to seafoam an engine is to suck up half a can (or until the engine stalls out) through a vac line as luckyedboy66 mentioned. I wouldn't put more than 1/4 can into the fuel tank. I'd just use half a can through a vac line (brake booster line works the best), and 5K later, use the other half can through the vac line again. Running Seafoam on a vehicle that's relatively new with low miles won't give you any benefit.
