How do I get Red or Blue Battle Fuel for my pet?
To claim battle fuel for your pet, visit www.mountaindewgamefuel.com and follow the directions there. You can receive one stack of five (your choice of either five Red Battle Fuels or five Blue Battle Fuels) every calendar day (which resets at midnight PST regardless of your actual time zone). After claiming the fuel on the website, you must log in to World of Warcraft with the appropriate character before the end of the day, or it will expire.
