When my "new" Sedan arrives on Monday, I plan to utilize the new aerosole seafoam and see how it works.

 

If you do, keep in mind it's not meant to be used on a running engine. With it being an aerosole spray, there's a very likely chance that it uses compressed co2. If that's the case you do NOT want to be spraying that in the engine with it running. I would personally just stick with the regular non-aerosole seafoam unless you plan on using it to blast the intake valves with the intake mani off..

 

Hey OP you in Buff? I go to school out there! Also about to seafoam my car, didn't know I shouldn't use the aerosole can with the engine on. Could I just dump it into a can and suck it in the engine that way?

 

Yep. Using engine vacuum to pull it into the engine is basically the tried and true method of using it. The aerosole can seems like it would be easier (and in principle it really is) BUT the fact that it's most likely compressed co2 just makes it a bad idea.

I actually just pulled a can of it off of the shelf and even the instructions specify to turn the engine off while spraying it, so i would have to think that my assumption of it being compressed co2 is most likely correct.

 

I did it a few months ago in the injectors but I got no smoke at all. I put about 1/3 in a cup and sucked it in while having my wife rev the engine. waited about 10 minutes then started her up and drove it around. I got nothin

 

I think you may be looking at the wrong product rather than what I'm referring to:

Seafoam Motor Treatment and Introducing NEW Seafoam Spray - YouTube

They're clearly spraying into a running motor with their new aerosol spray.

 

Nope, that's the same stuff. I'm still not crazy about spraying compressed co2 into the engine though (assuming that's what they're using to make it an aerosole of course), but that's just me..

 

Wish me luck!

 

lol....

So are you going to hook it onto the throttle body or blast it directly into the manifold through a vacuum port?

Found one of the other pic's I took ....

 

Must be nice to have an LSJ!!!! How you been ??...... Keeping the place in line I see hehe. How the H62 doin?

 

Rukkee: What is your driving style? Is it mainly stop/go or is it mostly highway? How high is your RPM normally during shifts/cruising?

I just ran half a pint of Seafoam through my 09 SS/TC, which is all factory stock. There was quite a bit of smoke, a LOT more than I've seen when I first used seafoam through my 81 T-bird (which was over 24 years old at the time).

However, I have my doubts about Seafoam doing the cleaning on the intake valves. There just isn't enough dwell time for the seafoam to break down that carbon. I think most of the smoking action is from the seafoam sitting in the combustion chambers and going out through the catalytic converters. The residual smoking (after a hard run) seems to be just the remaining seafoam in the exhaust pipes.

 

I would say aggressive driver ...... every time i drive it I get a decent 2nd gear pull out of her. I live in the country so some stop and go but not much .

when I seafoam I will let it sit for 15-20 minutes before i fire it up ......and it smokes real bad for 3-5miles each time . Its a little embarrassing when i do it and drive by my neighbors otw out of town lol. I don't have cats but im sure the inside of the exhaust piping is enough carbon to make the smoke show .

ONE thing i recommend is to have someone in the car to shut it off while your still ingesting the seafoam........If you have to run for the key then you dont get as much seafoam to stay up on the valves ......most is prolly in the chamber by then .

I dont rev my car alot ..... usually 3K max for most driving ... and when i do get on it im shifting at 5500...... it falls off enough up there to where i usually shift ( unless a race pops up of we make it to the track ....then ill shift at 6K)

 

I hope my valves look like that when I get to that mileage. I did that on my car at 25k and did not get much smoke. It was definitely noticeable, but not very.

I went and did my Dad's Nissan Juke with 18k miles right afterwards, which is also turbo and DI, and got unbelievable amounts of smoke. I couldn't see anything out of the rearview mirror for about the first half a mile, and it still had noticeable smoke after about 15 minutes.

I did the same procedure on both. My Dad babies his car with slow acceleration and always aiming for best mpg. I am known to enjoy the acceleration of my car, but I do a lot more highway miles than he does. I'm not sure what exactly makes the difference.

I also did see a noticeable improvement in mileage on each car. My average mpg monitor on the dash went up about 1 mpg, while his went up about 2 mpg. He keeps logs of his gas mileage and has a visual display of the gas mileage per day over the last week in the car, and both of those agreed with about a 2 mpg difference.

EDIT: One more thing to note, I work at a Nissan dealership and our techs use an aerosol product to do what we call an 'EFI' on the Jukes that has a similar result. They use it with the engine running with no problems.

 

What product do they use at the dealership, and how often do they use it on the cars with DI engines?

And this: MOC Products - Preview Information

I'll double check at work tomorrow, but I'm pretty sure they start with the first, then do the second.

And they recommend every 15k miles, same as my Chevy dealership recommended for my car.

 

I'm trying....

I'm good man!! Nice to see you're still around. The H62 is still putting a smile on my face.
