I never really believed the seafoam hype but my car has felt sluggish as hell lately so I decided to try it. I bought a 16 ounce can and ran half through and cleaned it out then ran the other half through. The car is much better now. It wouldn't hardly turn the tires over from a roll before, after the seafoam it spins like hell and is all over the place and pulls much harder. I HIGHLY recommend seafoam for whoever was on the fence like me. Seafoam:thumbsup:
