Zac Efron is Audi Awesome

Zac Efron rocks out a Keema Megabucks t-shirt while filling up his Audi S6 at a Mobil gas station in Toluca Lake, Calif., on Saturday afternoon.

While his gas was pumping, the 21-year-old High School Musical star was seen twirling around his car keys and sending messages on his iPhone.

The night before at a Lakers game, Zac met one of his idols, actor Leonardo DiCaprio.
