breaks the oil down....no
thins it out yes......

 

Seaform will thin your oil plus clean to much if the motor has more than 50,000 than dont put it in. You find leaks the sludge would normaly block up.

 

Is it to much trouble for folks to actually use the search feature???

 

here is the company who makes it. click please put all questions in here. this will help keep it centralized and easy to find for info.

 

I just used Seafoam for the first time on my 2000 XJ. I waited till the tank was down to about 1/4 tank. I poured one full can into the tank. I drove around for a little while and then let it set over night. After about two days of driving and letting the seafoam run through the engine, I feel 100% difference in how the engine runs. The engine ran good for having 120,000 miles before but now it idles, speeds up and performs better.

Just my 2 cents.

I hear stories about the terrible clouds of smoke during and immediately after installing product. Your comments please. Thanks.

 

The smoke means it is working. ;-)

I have used it for years on boat motors, used it on my 1945 Farmall tractor too. Haven't gotten a bottle for the XJ (owned for about a month now) but will certainly have to pick up a new bottle.

 

Yeah, happened with my car.. just getting rid of "stuff" and means its working.. if i remember correctly it says so on the bottle to do it in a well ventilated area

 

I used it once before on my xterra. I sucked it into the engine with a vac hose. I let it set for about 30 min and then started the engine. The smoke was so thick, it looked like my house was on fire. It smoked for about 10 min and then stopped.

When I poured it into the gas tank, there was no smoke. It ran perfectly normal.

 

Do not start anymore seafoam threads. We have this one and that's plenty.

 

my thoughts exactly i see these every day. i think a lot of people have questions please put them in here so it can be in one easy to find place

 

Seafoam is basically a solvent, like dumping acetone into your car. It breaks stuff up like carburetor cleaner basically. If it's smoking badly, it probably means you'll feel more of a difference.

I've used Seafoam in several of my vehicles and the only one that ever ran any better was my Isuzu pickup. I think it cleaned out the EGR valve. On a vehicle that runs fine (or pretty close to fine) you probably won't notice much of a difference.

I never run seafoam or marvel mystery oil in my crank case for longer than 100 miles. The main worry if you have a terribly sludged engine is that you can plug passages with goop and create hot spots in the block or completely block off oil flow to critical parts. This hasn't happened to me and most of my vehicles are fairly well maintained already.

Overuse of seafoam will probably cause premature engine wear. Cylinder wall scoring and all that good stuff. I typically use it once, when I first buy a vehicle to clean things out and start with a fresh slate.

As for the oil, I like to do things more slowly. I switch to synthetic oil and before dumping it, I'll dump in some seafoam or transmission fluid, or whatever else will clean gunk off of metal.

I find that targeting bad areas of a vehicle is more effective than 'miracle in a can' Clean the throttlebody correctly, the idle air controller, EGR valves, etc... Then do a leakdown and compression test on the engine to look for bad valves, rings, head gasket, etc...

If you have a healthy engine THEN dump the seafoam in. Otherwise, you should probably fix the other issues first.

I put seafoam through my '54 Ford sedan and completely smoked out a city block. It was pretty funny, but my car didn't really run any better afterwards. It already runs about as well as it's going to.

 

Has anyone gotten complaints from "smoking up the block" before when using this? There's nothing you can get in trouble for by smoking your truck like this, is there?

 

If anyone hasnt heard of this there is also a good product called bitron that you can run in your engine after you have cleaned it out with seafoam. It is chemically engineried to be attratcted to heat, so hence lubrication where you need it most. I run it in my xj in the oil, the brakes, PS, differentials and you can run it in your gas but I have something even better for that.
