女听众：Hello this is Sarah Jane from Boulder Colorado

Car Talk: hello Sara Jane’s, Sara is there an H in the end of your name?

 女： no, there is a hyphen,

CT: ah my god, not even Sarah Lee has a hyphen, exactly right,  I like it and you  have a hyphen in your last name too, like McDonald Douglas?

女：No

CT:Liggett and Myers,

CT: Wow, where are from Sarah Jane?

女：Boulder, Colorado

CT: OK, what’s up?

女：well, I have a very simple general maintenance question, I have a 1992 Subaru Legacy wagon, and ah, the owner’s manual says that I should change the oil every 3000 miles or three months, and I heard that you guys said that 5000 miles is fine, but I don’t drive a thousand miles in a month so for me to change every 5000 miles  would be every 6 months.

CT: perfectly adequick.
