Zac Efron is the Gas Man

Zac Efron spends his first Friday after his 20th birthday all around town in North Hollywood.

The High School Musical star first visited an office building in Century City before stopping at a gas station to fill up his Audi. Later in the day, Zac showed off his bulging biceps as he headed to the gym for his regular work-out.

Zac’s jeans are “Mick” Straight Leg Jeans by J Brand.
