are there something better?
 
It works great. Only thing comparible is the professional level decarboning systems at shops, but then a can of seafoam is $7-$8
 
I have seen sea foam work magic in outboard motors and ATV's. Went from barely running and getting to half speed to running like tops in about 15 minutes if that. I have also had it turn check engine lights off for unknown reasons before I purchased my code reader. Only used it in gas though.
 
Only thing I have seen better than SeaFoam is a tear down and wire-brush.
 
You guys are talking about as a carb/fuel injector cleaner additive right? How does Lucasoil's product compare?
 
I am talking about as an induction cleaner. As a fuel additive Lucas is a good product.
 
Adsm, when you say induction cleaner, you mean injecting it into the air intake while running to burn out the carbon?

I did that with our Jeep. It was dark out, knew it was doing something when the exhaust manifold started to glow...
 
I've never used Seafoam, seems way over priced compared to Berryman B-12. It is just a solvent bomb (MEK Acetone and the ilk).
Myself I don't seen the harm in using any fast solvents to clean a fuel system, done it myself with no adverse effects.
 
I've had great success with it as a fuel additive and crank case oil additive. I couldn't tell the difference or maybe had minimal success with it in the intake, but it's possible there wasn't enough seal around the intake with the straw in there so it was getting a leak post-maf. It cleans pcv valves and other things with carbon residue very well. Might even work as a penetrating oil if you don't have any PB. I'm sure it would work to pull carbon out of your autoloading guns too.

Nonetheless, good product. Always have a couple cans on hand (both spray and pour)
 
ATF makes a great decarb but it will destroy your cat/s. Bring the engine up to temp and suck half a can of seafoam in the brake booster hose and quickly shut it down. Let it soak in for 1/2 an hour and then start it and run it around 3000 rpms until the smoke show stops. Just make sure all the windows and doors are closed in your house the more it smokes the more carbon it it burning off. Just put the other half in the tank.
 
I've heard about running ATF as oil for about 20 minutes (maybe a couple shorter cycles so it doesn't hit full operating temperature), then flush and it cleans carbon deposits from the crank case. I haven't tried it (don't really want to either), but it's been from multiple people.
 
I did it in my 99 Dodge Ram 1500 right after I got it, and I sucked 1/2 a bottle through the brake booster vacuum line, shut the truck off for about 20 minutes then started it back up and held the throttle up a bit. It smoked for about 15 minutes. After I did that it ran awesome I could tell a power difference afterwards.

Be careful about doing this in these newer vehicles you may set off all the dash lights did it in my 08 Toyota Tundra and the dash was lit up like a Christmas tree afterwards had to have the dealer do a re-calibration of the computer to reset it LOL.

I also did it in a riding mower I picked up last year, it had a terrible carb issue, and wasn't running too well otherwise. Dumped a bit in the carb shut it off and let it set, then started it up about 20 minutes later and had a smoke show at full throttle for about 10 minutes, it's ran awesome ever sense.
 
Not only does it work but you get to see a cool show as well.
 
If you have a older engine without a cat run it around 2000 rpms and slowly pour ATF down the carb until it starts to smoke and then run it at high rpms for a bit then do the same with water and rev it up the ATF will clean the valves and rings and then the water flushes it all out kinna like a steam clean. I did it on a old dodge 360 that sat for four years had two dead cylinders and brought it back to life. It gets the valves spinning again.
