I'll point out this is the "Ben Kenobi/Gandalf" connundrum. Why does Obi Wan need Luke or Gandalf the hobbits?
1. Mentor can only be in one place at a time and whatever he's doing needs at least two pair of hands.
2. Mentor is holding back in case they run into BBEG. "I'll deal with the Balrog/Vader, you go ahead!"
3. Mentor's gotta sleep.
4. Mentor is great wiz-bang mage but hasn't left his tower except to go to Wizard's conventions since he was an apprentice. Can't cook, has no idea how to navigate cross-country, hates horses, couldn't track an elephant across a muddy field. Basically, he's field artillery and needs someone to get him where he needs to go.
5. Mentor hasn't told PCs he's heap-big-mage. Why? The pestering (can you cast fly? Will you enchant my sword? Tell me my future) should be avoided. He's Rich Guy #4, who needs an escort to get to the Hills of McGuffin. If the party looks like they are going to have a character death he'll intervene, preferrably as subtlely or scroll/wand based as possible.
