This taken from their respective MSDS sheets. Anyone who tells you TEC is the

Just to follow up on the instructions given above, you want to pour the entire can in (slowly) the vacuum hose. One that feeds ALL of the cylinders (brake booster or PCV). Then you hop in the car, raise the idle to 2000rpm, and shut it down when you see the white smoke.
