good info...I'll buy some.
Here are Sea Foam's directions. Hope you don't mind that I copied & pasted from there.

1. (Noted Above- see post #1)
With engine warm, slowly pour 1/3 to 1/2 pint through carburetor or throttle body throat. (If vehicle is port injected slowly pour SEA FOAM through direct manifold vacuum line that will feed all cylinders, possible sources are P.C.V. valve or brake booster line.) This will pull SEA FOAM down on top of the pistons and to the back of the intake valves to dissolve carbon. Turn ignition off. Restart engine after 5 minutes. If severe carbon build up is apparent, use more Sea Foam as previously directed. Make sure exhaust is well ventilated when using Sea Foam in these various ways as fumes will be extreme for a short time.​
2.
Pour 1/3 to 1/2 pint into oil crank case to clean rings, lifters, dirty parts and remove moisture.​
3.
Pour 1/3 to 1 full pint into fuel tank to clean injectors, carburetor jets, fuel lines and remove moisture.​
