Hello Jason2,
Question #1 Honda Item, I don't know of any other plug for the Insight, they have to be matched to your engine.
2. Would not be Insight related, the insight does not have spark plug wires, it has a coil on top of each plug, they should last 100K miles.
3. As for oil, Mobil 1 is used by most. (we should do a survey on this)
4. Of course
