When I first used it, the recommendation was to slowly pour it in the vac line, then let it stall after 1/2 a can or so (pour it in faster).
Then wait 5-10 minutes for the solvent to start working on the gunk...
...and then go out crank it over. Then "briskly" accelerate the vehicle to blow out the carbon in white smoke form.
If you left it running, the smoke would build-up in the area where you're working, while you re-attach the booster line. You really have to drive the vehicle to clear all of this out. I haven't had any vapor-lock problems in over 10 applications, in different vehicles. Has anyone had this problem?
The problem I have with most of the other brands is that you have to special order them or go through a dealer of some sort. I just go to the auto parts store and pick up a few cans of SeaFoam.
