Based on Seafoam's instructions, I warmed the engine up good, then put 1/3 can in the oil, 1/3 in the gas tank, and 1/3 can through the brake booster vacuum. The engine will probably quit unless you work at keeping it running until it's all in.
Then let it quit or turn it off, wait 10 minutes, start it up and take an agressive drive for 10 minutes or so. Enjoy the strange looks due to all the smoke. Done.
Results depend on what is actually wrong with the car. On the Subaru,it seemed to smooth out the running a bit, must have cleaned something out of there. Putting it in the oil definitely quieted badly ticking lifters after a while.
