Seafoam cleans out the engine basically and yes it is fine to use on your car. Just make sure to do it at night or something because of the amount of smoke that will pour of our your exhaust.
put 1/3 of the bottle through the vaccume line, and por the rest in the tank. Let it sit for about 15-25 min after you suck it through the vaccume line. Then start the car, and enjoy the smoke show
