FLT#8576, STI-FLL. 'DURING CLIMB  WE EXPERIENCED  A LEVEL 2 FUME EVENT AS PER FOM  AND FCOM  VOL 1. THE ODOR  WAS AN OILY  GREASY CHEMICAL SMELL  .. WE PERFORMED  THE ODOR  ISOLATION  PROCEDURE  IN FCOM VOL1. STEP #9  DROVE US  TO ISOLATE PACK 1  WHICH  MADE  THE SMELL  GO AWAY. MCC  AND DISPATCH  CONCURRED  VIA SATCOM  THAT THE  APU WAS  MOST LIKELY  THE SOURCE  BECAUSE  THE APU HAS A HISTORY OF LOW  OIL LEVELS, AUTO SHUTDOWNS, AND APU GEN FAILS.  THE LEVEL 2  EVENT  WAS PERSISTENT  UNTIL PACK 1 WAS TURNED  OFF. IT WAS DETECTABLE BY MULTIPLE  CREW MEMBERS. MILD TO MODERATE  IRRITATION  REPORTED  BY MULTIPLE  CREW MEMBERS, INCLUDING  HEADACHES  TINGLING  NOSES, AND IITCHY  EYES.
