Question Seafoam?

Car: 1999 Z28 M6 (61k miles)

Just bought the car and would like to do some maintenance. I am getting semi-poor gas mileage and I figure some cleaing couldn't hurt. I know seafoam by some is considered magic in a bottle but I am not sure the best way to go about using it. I would like to get it straight into the motor (i hear the car will blast tons of white smoke, i dont care ) Just wondering how much to use and how to get it in? I have heard using the vacuum from the brake booster. Also, The plugs shouldn't need changed yet but I am still trying to figure out the poor gas mileage (around 13 mpg normal driving).

Thanks!

if you're getting that poor of gas mileage i would definitely pull some plugs and check them out to start with. just b/c they "shouldn't" need changing doesn't mean they don't. if you can find a guy locally that has HPTuners i'd also scan your car to see how you're running(lean or rich or whatever).

what mods do you have done to your car?
