Movies. Find out his favorites, ask him what he's seen recently and if it was good/bad/etc.
His family. Find out about his siblings, what his parents do, etc.
His future plans. If he's 3 years older than you, that makes him 17. Find out what he wants to do after high school, what career he's interested in, and what he wants to do with his life.
Basically, just find similar interests, and take in interest in him. Show him you're interested in what he has to say, but don't only talk about him. Talk about yourself, too.
