Cigar lighter

[Chris H]

Hi,
Just got a Z last summer. The cigar lighter doesnt work and i wanna hook up a radar detector. Another quick question ive seen alot of different numbers and post on special things for changing the oil. What is the right amount of quarts, what type of oil and what else do i need to be aware of when changing it, plugs and wires and fuel filter were recently done i saw something about a PCV valve and throttle body cleaning anybody know about this. I know this is alot but i dont want to mess it up gotta keep this awesome car in great shape.
