anyone ever used seafoam cleaner? i was reading about it online and it said add 1/3 to gastank 1/3 to engine oil crankcase and 1/3 to vaccuum line. but people were arguin about how much to put in and whether or not to just let idle for 10 minutes or drive for 10 miles after seafaoming. so i was wondering if anyone has ever used it and could tell me exactly what to do with mustangs.
