Yesterday afternoon Benji Madden saved the day for a pal stranded on a busy street in Los Angeles, and X17 photogs caught the entire incident!

The inked up Good Charlotte rocker happily filled up his friend's empty tank and kept his cool when photogs asked all sorts of questions. Hmm, maybe next time we run out of gas we'll give Benji a call! He's way hotter than the AAA guys!
