i used a can in the gastank on my 85 supra. was maybe at 1/2 tank (~8 gallons). got on the interstate right after putting it in and withing 5 miles i felt a difference. it was obvious. while cruising, it just all the sudden increased in speed and ran smoother. i had never run any cleaner through it before and car had ~180k at the time. i bought it at ~155k. its got over 205k on it now. original engine, only thing done has been maint. timing belt, all front seals, valve stem seals, valve cover gaskets, etc.. all done at 170k by me. other then that just plugs and oil changes.

IT SURE DOES, it cleans the valves and top of the pistons.. before there was seafoam and common fuel injection, we used to hold the carburetor at about 4500 rpm, and pour water down the carb, slow enough not to kill it, and all kinds of carbon would fly out the tail pipe...... this would keep your motor from "pinging" ... oh well, old time stuff...

yes it does work. never put it in the gas tank cause i was told it could eat away your fuel filter. so instead i took the vacuum line from the break booster and stuck it in the can just above the liquid so i could suck in the sea foam little at a time. you'll see a huge cloud of white smoke once it gets in the system. run the motor till the smoke clears and youll have a better running car.

Not a good idea to add it to oil though i think. It causes oil film to break down.

What is seafoam: http://www.seafoamsales.com/

Where can it be purchased: Any auto parts store, wal-mart, or store that sells things and stuff, honestly.

~7.99ish a bottle.

I used it on my old '87 cutlass and it seemed to work okay, but I put 1/3 into the gas tank, 1/3 into the crankcase, and 1/3 through the carb while it was running.

From what I've heard, using the vacuum line is your best bet.

Seafoam works best when being used with the vacuum lines. I wouldn't bother using it in the gas tank since there are MUCH more effective bottles of fuel injector cleaners out there that cost the same, if not less.

Avoid adding into engine oil if you can. If the internal of your engine needs cleaning, then use Auto-RX. It's a lot safer and quite effective. Great stuff to use if you have a sludge-prone Toyota vehicle.

Before you use Seafoam through the vacuum line, try using water first. Water decarbonization has been around before these solvent cleaners hit the market. To me, it's more effective in most applications, which is probably why I don't buy Seafoam anymore. $8/can vs $0.25/gallon.

I know this is an exception but I used it and had seal problems that cost me $720.00.
This stuff worked so good that it cleaned something that was keeping the seal from leaking.
