Seafoam (wow)

I dumped 2 pints (the measurement of the cans) into my gas tank. (42 gallons but it was only 3/4 full.)

I have noticed better fuel economy and better idling. And while I'm driving I've noticed the small hesitation go away!

Seafoam rocks! When I do my oil change I'm going to dump a can into that too!

P.S. I drove from Wisconsin to Minnesota. The road are terrible!! You can't see the road, and the snow is drifting. I haven't seen it this bad in quite awhile!

USE SEAFOAM! :)

Seafoam is 100% Petroleum. It says so on the can. I just bought some for myself but won't use it until just before my next oil change (about 2,500 Kms). I've heard a lot of good things about it but if used improperly, it can do a lot of harm. In my 227,000 Km Escort, I'll be using half a can/pint in the gas & the rest will be split 2-to-1 between the oil and intake. I'll keep you posted.

Once a year its good to put in the engine and its important to change the oil within 100 miles..

20 or less if you put it in the oil to clean the sludge out..

DO NOT PUT THIS IN YOUR OIL!

The most effective way to use seamfoam is to run it into a vacum line...I did it on the Grand Prix, and while it makes a difference, you have to be sure to change your oil after doing this

Seafoam thins out your oil like crazy......

Well of course! Im a gearhead! What i would do if i added it to the oil is..... id change my oil, run the seafoam in the oil for maybe a few days and then change the oil again.

Ive used tranny fluid in my oil before to clean out the enigne as well. I dumped a little in (i forget the measurement) and drove about 60 miles, came home and let it drain overnight. The stuff that came out was a bit dirty (even though it was a fresh change.) It did wonders.

I think seafoam is safer though.

I like to pull the brake booster hose while it's running and slowly pouring a half a bottle in then let it die. I let it sit for about 45 minutes then take a drive to blow it out and scare the hippies. Works great!

I pour the rest and another full bottle into the gas tank and chase it with about 15 gallons. When that gas runs out it's time to change the oil.

I have also used it in the crankcase of my mother's 2000 Dodge Sludgemobile.

Oh, and I get it at O'Reilly.

Stick with seafoam.

My truck has been idling better after i dumped 2 pints into my gas tank (because i have a 42 gallon tank, I had to use 2 cans. I didn't have my tank full, but 3/4 full, so it got a little higher dose, but thats fine by me.)

I'd reccomend it.

Hi
I tried putting seafoam into my 2002 Silverado's throttle body throat, but I just ended up spilling it all over my belts. :D Seafoam is flammable, will it being on my belts with the friction cause a fire? Also...Can someone tell me the location of a vacuum line on a Silverado 5.3 V8?
 
#21 ·
Everyone is right...WOW. I let the belts dry off. Dumped some seafoam in the brake booster line, the rest in that gas tank. Hesitation is gone. I have a huge power increase. This was my first time to seafoam my truck and I'm very happy!

No...LOL. It actually didn't smoke a whole lot. Yeah, It smoked, but not like I expected. :( I liked the smell though. It smelled like fireworks. :D

brake booster hose? where is that? if you cant already tell, i get nervous touching anything under the hood (or anywhere else for that matter) unless i know exactly whats going on.

If you do a search on the internet it can tell you where to put the seafoam. and how to slowly pour it in..Very important NOT to hydrolock the motor.

I pulled the pcv valve hose and shot it into there.. (spray can of seafoam gives less of a chance of hydrolocking the motor)

Don't do it more than once every year or two at most and change the oil within 100 miles or thereabouts...

If you don't feel comfortable doing it yourself.. you can instead of buying a can of seafoam for 5 or 10 dollars have the dealer do a decarb procedure on your car.. for about 100 bucks if I remember correctly...

is that what they do at the 30k mile mark when they clean the injectors and all that good stuff (i forget exactly what they called it)? i just had all that done. il prollyjust put it in the gas tank.

Probably? I have no way of knowing but it sounds logical.

I throw a bottle of Chevron Techron in the gas tank every 1000 miles and I try and use Tier one gas..ie shell or chevron.

If you do that you don't even need seafoam..

Chevron techron is sold in most autoparts stores and it just goes in the gas tank..

IMO if you do that you don't have to use seafoam. (unless you have a drivability issue)

The first time I used it, it was reccomended to me by a mechanic who worked on cars, planes, and boats. He told me it has been around awhile but only for pros. He said every engine he used it in, when tored down looked like new. No sludge, etc. He told me on the '78 Corvette I had just purchased to put fresh oil in, then Seafoam, run it for 500 mi. then change oil. The oil came out like oil with 12k on it. I ahve used it as fule treatment, carb cleaner, engine flush, etc. My gf's sister had a car bucking and not running right at all. I told her before you take it in, pour a can in the fuel tank........within ab out 10 mi the car ran perfect. I suspected she had a bad injector and it cleaned it. I have had no problems wiht this stuff, only positives
