Richard wants to know if that oil smell is a big deal or if it's just an infinitesimal leak from his Infiniti.

Richard notices that when he hits the "resume" on cruise control, it accelerates much faster than he would if he were accelerating manually. Is this good for his fuel economy?
The transmission on Bill's 2000 Volvo V70 is slipping. Is it safe to keep driving it? Car Talk's take, right here.
