Hey has anyone used seafoam before?? If so, how did you use it?? thru the gas or your crank?? and how did you do it? because i bought a can and i dont see and directions to use it

I pour it into the gas tank at one can to a quarter tank of gas.The directions say to add one can to a full tank.Seafoam is only about 40 octane so watch for detonation.

According to the website, you can do it either through the crankcase, oil filler, fuel tank, or even all three. Most people put it through the crank case via the brake booster or PCV valve.

i have seen videos of the cloud of white smoke coming out...why does it do that?? and where do those people put it?? because mine didnt do it

I use spray T/B cleaner to clean the intake tract on my 04.
I pull the hose off the IAC and stick the straw from the spray can into the hose,then replace the hose.You can then stick the straw back into the spray valve,start the engine and spray away.It works a lot better if you warm the engine up to operating temp. before cleaning.This cleans the IAC,the runners of the lower intake,the outside of the injectors,the head ports,the backs of the intake valves,and some of the carbon from the combustion chambers.
If you spray enough in to cause the engine to stumble you will eventually get the white smoke.The smoke has a light oily smell that I'm sure comes from the kerosene base it's made from.
