So I asked a question a while back, and the answer that was given has been bugging me. I finally did the math, and here is the result.

Kentetsu suggests 1 can in 1/8 tank of fuel, and then drive the **** out of it to clean out the motor. That is 16oz of sea foam in (if you have a S3) 2 gallons, or 256 oz, of fuel. Ratio of .0625 oz seafoam/oz of gas.

I asked if you could put a gallon of sea foam into your tank and then drive the **** out of a full tank to really clean out carbon deposits. 128 oz of sea foam to 16 gallons, or 2048 oz, of gasoline. Once again, a ratio of .0625 oz SeaFoam/oz of gasoline.

I'm contemplating doing this, as it is no more concentrated than what Kentetsu suggests for a good cleaning. Any thoughts?

 

if you're concerned with seafoam eating up any rubber or plastic pieces, then add it with 1/2 tank of gas.

 

seafoam wont eat up your lines

you worry too much and make sure you have a clean fuel filter after your done.i love this stuff

 

OK, so if you want it more concentrated why not pour it straight down the primaries and secondaries while the engine is running? That way your smoking event happens in your yard, not while you are out on the road attracting attention?



If you really want to give it the treatment, pour enough sea foam into the carb to choke it out, then let it soak with occasional turning for a few days, it works wonders although it can be a little hard to start back up sometimes.

 

Done that also but with a 2 liter of water per rotor

 

My thought. That would be a hell of a lot more expensive than just using one can to a 1/4 tank of fuel. Seafoam is what, $10/can? 1 can for every two gallons. 16 gallon tank. $80 for Seafoam. Or just wait until your low on gas, dump $10 into your tank and be done with it.

 

if you dump 1 gallon into a full tank its gonna take that much longer to burn all of it off, and you're gonna have to do tons of driving, else you're gonna have the cops all over your *** until all that **** is burned off.....i'd either put it down the carb, or 1/8 tank of gas be done with it quick and get the same results since the concentration is the same.

 

I've done it in a 1/8 tank and it doesn't smoke.

 

i've done it both ways, of course pouring it down the carb lets more smoke out, waaaay more, but there was still some smoke coming out by pouring it down the gas tank.

 

I usually recommend the 1 can to 1/8 tank if someone has a motor that is in really bad shape.

For a daily driver in good overall condition, you can put it in however you like. I will add the Seafoam whenever I feel that the power is dropping off a bit, or before a big race or road trip. On those occassions, I'll just throw a can in with a full tank of gas. It doesn't really matter. You could probably use 1/2 a can of Seafoam and get the same results. It works fast, and it results in a noticable increase in power, both on my last (very worn out) motor, and on the new one.

What I really want to see is someone doing a dyno run. First without seafoam, then with it in the tank. I swear I can feel the difference, but I'm not sure if it is the cleaning action or the Seafoam itself that causes the increase in power.

 

I've used it about 5 times and so far no smoke at all. The only time my car really smokes is after it's been sitting awhile, usually over winter, and if I redline it and come off the throttle, then my worn out oil control rings let some oil into the combustion chamber and I get a nice smokescreen.

 

Can someone post a pic of the actual face of the can...

I've always been reading about this stuff but never ran across it in a parts store and have a 12A in desperate need of being woken up.

Thanks.

 

"Done that also but with a 2 liter of water per rotor "

Wacky, you are crazy. But I'll bet it works.

lol, love the random pic and link

 

should be getting some this week. gonna try it in my se.

last year I ran water for each rotor. 1 gallon total i think.

 

another thing you can do is pour it down the carb, and let the car sit. Just get 2 cans. For the first one pour down the carb to each rotor. Let the car sit for 24 hours. Rotate the engine by hand 180 degrees at the 12 hour mark to make sure its goind around. Also do it counter clock wise of the normal engine rotation so that you're not just pouring it down the exhaust. If you have an old set of plugs you should probably put those in to not foul the plugs you have in there. If not, take them out and put bags or tape on there.

Next day with the spark plugs out, crank the car as much as possible. Have a blanket or big grabage bag infront of the plugs as it will shoot out quite a bit. Once most of it is off, put everything back in and start her up

This is probably the most extreme way of doing it.

 

Another deal is get the spray can of GUMOUT Carb and fuel injector cleaner. Rev and hold at 3,000rpms and keep spraying down throat of carb. Works wonders, really does. Easy to find. Then pour the seafoam in the tank to clean out carb internals and go for a drive.

 

I hate Math...lol

 

I think his reasoning is that even though it's just as concentrated, he'd be doing a much longer clean out. With 17 gallons (combined amount) of fuel/seafoam mixture.

 

exactly...

 

I havent tried a seafoam on an older cars with EFI. Is it really good in cleaning the injectors?

 

It hasn't caused any problems with my 4.3L Vortec CPI and god knows that thing is prolly as archaic as the SA in age.

 

i get the point, but the way i see it is for example cleaning around the house, you're not gonna clean the same spot multiple times when you know that you've already done it once and its spotless....its just something that you'll save up money and time if you just do it once. but in the end it IS his money and his time.

 

$80 worth of seafoam... Rebuild gasket kit only runs about twice that, if you want CLEAN...

 

This is basically why I say to run it through the gas tank, rather than dumping it down the carb or sucking it in through a vacuum line. All that smoke that goes out the tail pipe is the Seafoam that you just paid 8 bucks for. I see that as wasted product.

When you run it through the tank it does the job just fine, and I think it is a better bang for your buck...
