View Full Version : Seafoam
Anyone seafoam (in gas, crankcase, or intake) the 3.0T motors here? I could only imagine it not being good for these motors but I was curious.

Why would it not be good? I assume the chemical is probably a bit harsh on valve seals - otherwise it does its job with carbon in any application. I don't see why you couldn't suck it up in a vacuum line like any car - granted I am not sure where you would get it in there as you probably don't want it to run through the super charger. I am a big sea foam fan otherwise.

I have a can laying around from my 2.0t days... very curious to see if anyone's done it, or if its even safe to go through the SC.

Considering a lot of the carbon buildup is on the intake valves, probably won't see as big of a benefit unless you suck it in through a spot in the intake system, or after the charger. I've done it to my old cars without issue.

The S4 has a direct injection engine, on a direct injection engine the fuel is sprayed directly into the combustion chamber, the intake valves never see any fuel, so Seafoam will not help clean intake valves.
It might help clean injectors though or clean moisture from your fuel tank.
Has anyone poured seafoam into the gastank with no ill effect?

use it in all of my vehicles and have for 20 plus years. Never had any issues.
Good stuff.
I purchased a low mileage Vette that sat for long periods of time, it would run out of fuel pressure on the track at about 125 mph during a long acceleration, like the fuel filter was starving the fuel flow, I discussed it with a mechanic I know and he suggested trying the Sea Foam and an octane booster, because it is about $1200 to change the fuel sock, I ran some tanks of 93 through the car with the additives, cleaned it up, the car will pull hard through third and fourth gear up to 150 mph now without a hiccup.

It would get drawn in through the intake to clean the valves.
Check out BG-44k. It's stronger than Seafoam but more than twice the price.

I'm actually going to pour seafoam inside the crank and gas tank about 300 miles before due for a change.
As for the charger. I rather remove that.
I'll let you know what happens.

I use sea foam as a fuel stabilizer in my 93 that I get for my snow blower and generator for the winter. The fuel sits for anywhere from 1-3 months depending on the last time I fill my gas cans. I put it in my car once spring rolls around and the car runs as smooth as it would as if it was fresh from the pump, no issues at all. I use 5-10 gallons of treated fuel at a time with no ill effects. I see no harm in putting it in the tank as a cleaner.

Looking forward to hearing your results
