Default Review: Sea Foam

So I picked up a can of Sea Foam after the How to clean your Throttle body post, and Heres my review:

Price: $10.71 with tax at Auto Zone

I was going to run the Sea Foam through my Throttle body, but since my car is drive by wire (I have no Throttle cable to manually open my Throttle, I'd need a 2nd person) I skipped it (opening the TB by hand really fubard my idle until I got it exactly where it should be (it wouldn't start otherwise).

I poured 1/3 of the can in my oil (then got an oil change the next day *headdesk* and poured 1/3 can in my tank (full).

HOLY COW the difference even in a car with such low miles is AMAZING (11,000 miles). There is

  • a LOT less delay in my throttle (I'd put my foot down, count to three, then go.. slowly).. Now I put my foot down, and I better be holding on, cuz she goes like a bat out of hell!
  • Lower RPMs: In fifth around 60mph I was at 2500RPM, now in fifth I'm at 2000(AC off) to 2250 (AC on high)
  • Better Fuel Economy.. Kinda.. sorta.. I'm assuming there is an increase, but look below.
  • Performance.. HOLY CRAP. I can spin my tires all the way through first gear! I can get a really healthy bark if I do a WOT shift into 2nd, and If I'm going down the road in 1st (there are 3 stop signs within 500 feet of each other), get my RPM's to about 4000RPM's, Hit the gas, and I'll chirp my tires. its AWESOME! - Downside, I'm going to be going through this set of tires way too quickly, and my fuel economy sucks.. (and my Focus only has 112ish HP at the wheels!)
Downsides: Your exhaust will smell funny (It smells like propane to me) The performance increase will probably lower your MPG (you'll want to floor it more often).. Totally worth it!

I give Sea Foam five cogs out of five. (Insert 5 cog smilies here)

It shouldn't smell out of the exhaust too long, just for a little while.

Either way, thanks for the review. I recommended it in the throttle body thread but I've never actually used it.

Edit: I also saw in the other thread that you plan on adding a third of the bottle every tank. That isn't the purpose of SeaFoam. It is a thorough component cleaner, meaning you only have to do it once for a very long time. Most people do 1/3 in the gas tank and 1/3 in the throttle (Like you said, you'd need a second person with a drive-by-wire) and that should clean everything for a long while.

I haven't bought another can yet, although with my move (600+ miles) today, I'll probably put another 1/3 in for good luck)

Gotta love sea foam. I've never used it on a car but i've used it on 4wheelers and jet skis and sleds.

Hm, I'll take note of that. I'm sure my Camaro could use some.

I can also atest to the usefulness of seafoam. It will definately clean the engine out safely. Just be sure to not let it suck it all up at once or else you could lock up your engine. Just a safety note.

I usually use seafoam every few thousand miles, but now I'm having my doubts about continuing to use it. I put it in my dad's truck when we gave him a tune up and now it blows a bunch of white smoke (Blown HG?) out the exhaust any time he puts it in gear (Park to drive, drive to reverse, etc) or gets on it hard. His truck never did this before so now of course he thinks it's my fault...

Yeah its not really recomended on high miliage cars because it can loosen crud that keeps gaskets sealed.

I wonder if the stuff works as well on carb'd engines as it does on FI ones...
