Seafoam...

Thinkin of Seafoamin my 98 Monte Carlo. Thoughts, concerns, comments? Come on guys, talk me into it. Practice your salesmanship lol.

It works. Enough said.

LOL. They have a few different products...which one do I use, how do you use it?

wat u mean by seafoam?

Use the Seafoam motor treatment. It works & is always the VERY first thing I do to any car that I get. Split it up into 1/3s. 1/3 in your gas tank, 1/3 in your oil, 1/3 through your vacuum lines. First dump some in your oil & gas, then take the remainder & run through your vacuum lines. If it's your first time, using a full can through your vacuum lines works to really break up the old deposits. You can use any vacuum line, I found that the one going from your brake booster or one that runs directly into your intake works best. It's going to smoke BAD if you are doing it correctly & don't be afraid to flog the throttle. After running it all through, change your oil & spark plugs. Spark plugs aren't always necessary, but at least check to make sure non of them have loose carbon deposit chunks stuck on them. The oil change is mandatory.

Seafoam takes some old rodder tricks & puts them into a can. Small amounts of water down a carb & some ATF in your oil before changing would do the same thing, but this is just convenient & safer than hydrolocking your motor if you don't know how fast to dribble the water.

I did a pressure flush with seafoam on my GEO. Before I was getting 20-22mpg. I used a 2qt pressure tank with 1/3 of it seafoam and the rest was 91 octane. Pressure set at 45psi and let it run, (took forever to get that little bit ran through) After doing so I didnt notice an increase in gas mileage much it was up to about 22-25 then. After 2 full tanks of gas it was up to 30-32mpg and I drive the hell out of it. I didnt notice any more power from doing so, but better mpg and it idled better. Definatly worth it.

Now with the new motor, double the horsepower and it running rich as sh!t with monster injectors and turbo, im still getting 22mpg. Im impressed

I've never heard of doing this pressure flush. What does this pressure tank look like and how did you connect, etc.?

Did you happen to replace the O2 sensor as well? That is a hefty jump in efficiency.

I noticed a jump from around 12mpg to nearly 20mpg when I done it on Brown Eye's old 305. It was pretty bad though. True story. Also, it got rid of the dreaded "305 detonation" that is so common on those POS motors.

Rago, I assume to get the gallon of Seafoam and split that into thirds?

Does the gas tank have to be full when I add it?

Sorry for all the questions...I'm just notorious for f'ing crap up when I try it...so I wanna make sure I'm doing it right.

Nope, just the 16(?) oz. Small size. The gallon I'm thinking is more for industrial use or shops that go through it a lot?

Pour into an empty gas tank when you are at the station, then fill it up. Just like adding octane booster or any other fuel treatment.

I just realized that I left out the most important part!

When you suck the Seafoam into your engine through the vacuum line, let it idle & suck all of it in. It's gonna bog down, so don't freak out. Shut the car off & let it sit for 15 minutes. THEN proceed to fire it up & give her hell. Sorry about that.

Whew, sounds like a lot...hope I don't F it up. Lol.

Thanks for the tips +1SC

Found this here...he put one whole can in the gas, half a can in the oil, half in the vacuum lines. Whatcha think?

I mainly see one thing wrong here. Seafoam goes into an empty tank & the gas getting poured in after will help to mix the Seafoam. Think of what you do for two stroke gas mix, always shake right? Same concept here. LoL, dude couldn't even get the gas cap back on.

Also, he poured at too fast of a rate & killed the motor. The Seafoam treatment is not hard to do, but it's a lot easier if you let the vacuum suck vs pouring it in.
