I want to know everybody's opinion of it and is it worth while using?

 

I use it in all my vehicle at least once a year. Matter of fact I used it on my Avalanche yesterday. I put in my fuel tank and put some direct in the engine through a vacuum line.

 

I used it in the gas in the tired 3.1. It took a few times but the difference was dramatic. I now use it pro-actively on other vehicles especially if they are older.

 

I've never used it, but from what I've read about it, it's supposed to work wonders getting the carbon buildup out of the engine. I've also read it won't hurt O2 sensors or catalytic converters if you don't overdo it. From the pics I've seen of one person using it, I think I'd do it in a remote area where there aren't any houses. I read where the neighbors actually called the cops on one guy because they were freaked out by all the white smoke. lol.

 

How about in the crank case then how long before you change the oil?

 

I've read that you'll want to change the oil before you put no more than 250 miles on it.

Found a writeup about how to Seafoam your car. http://diysrc.com/how-to-seafoam-your-cars-engine-to-clean-and-dissolve-carbon-buildup/

 

I love the spray. A real life saver for vehicles that have been running rich, cleans the cylinders right out. Really awesome because it also does a decent job of cleaning out intakes, plenums, runners, carbs and throttle bodies and many other parts in line after the induction system without the need to remove, clean and replace them.

 

I done it when my neighbors were having a cookout BBQ. LMAO! I wasn't invited.

 

If i do the vacuume thing, does it matter witch vacuume line i use?

 

Water will de carbon an engine too. I've never seen carbon deposits in a cylinder with a blown headgasket that allowed water in. That water cleans it up quick.

I'm not really a fan of dumping things in your fluids. If they were good for your car the OEM's would require it or do it themselves OR they would already be in the fluids to begin with, and most fluids DO have detergents in them these days that do the same thing.

This is what is in seafoam:


50% light hydrocarbon oil (pale oil);
30% petroleum naphtha;
10% isopropyl alcohol;
10% water.



It's not magic, it's just chemicals in a bottle that may or may not be a good idea.

I'd just mist water into the throttle body if I wanted to clean gun out of hte engine. Apply caution if you have a MAF.

 

If you drive you car the way I drive mine and use quality fuel, you will never need to worry about carbon deposits in the cylinders or gummed up injectors. A fuel with a good additive package like Shell, Chevron, or Union 76 will keep your injectors and intake valves clean. Getting your car out on the highway and especially opening up the throttle regularly will keep the piston tops clean.

I perform what we call a TBC,which is an injection cleaning process using the Motorvac system and cleaner, along with an intake and throttle body cleaning using the BG mist injector and BG's cleaner. These products are much more concentrated than anything you can buy in a store, including Seafoam. I do this service on vehicles that see alot of in town lugging around and especially those who's owners use cheap fuels.

 

I was working on a 86 vette that I suspected it had dirty injectors, I got it up to operating temp & ran all 3 cans of the BG cleaners through the injectors. Ran like new after that.

 

I used it a few months back on my L98. I used the power brake assist vacuum line to suck it out of the can. Blew a ton of black smoke out, runs fine now. Of course, it wasn't running bad before I used it, but I think it did help. I may use it again on my 4th gen Camaro 3.8 that has over 180K (and it runs fine too).

 

I used the power brake line. I think you're supposed to keep the hose near the top of the can and gradually tilt it as it sips the fluid out. Don't think you're supposed to put it in like a drinking straw. I think that would choke the engine too much, kill it, and thereby ruin the effectiveness of the a Seafoam. But the power brake line is about the same size as the opening in the can, so you get a decent seal, but you don't want it to seal completely. You need a little air to facilitate the syphoning effect. I think the small vacuum lines around the intake might be too small to do this. I could be wrong..... But this also allows all the other lines around the plenum to work normally, while still introducing the cleaner to the system.

 

I hear so much great things about it but I really didn't notice a difference on my high mileage 305tpi. I got a little bit of smoke but it was not nearly what everyone describes it as. Once I started driving it after putting it in there wasn't much smoke at all. I used the power brake assist line and put a third of the bottle in the tank. didn't notice any real benefits from it. I'm tempted to try it again though

 

I used the entire bottle. I got a good bit of smoke, but not huge black clouds either. I just attributed it to the idea that my car wasn't all that bad off. I didn't noticed a huge difference either, but there was a small but noticeable difference. I may also try it again to see if I can blow out anything else that may be left in there.

 

I've heard guys talk about a method where they load the intake and top end with the cleaner , shut the motor down and let it soak for 30 minutes or so, then run it out. Back in the bad old days at GM, there was a method like this for carbureted motors where we poured the GM top end cleaner down the throttles gradually at first then faster til the engine stalled. Then let it sit for an hour and run it out. Ignition tune better be good though or it may not restart at all. Lots of smoke.

A lot of areas, especially in California, you'd get into trouble if you did this very much.
