Where is the 2012 Ford Focus fuel pump relay located?

When I get my oil changed, do I need to ask the mechanic for a specific kind of oil? If so, I have a 2011 Subaru Impreza—what should I ask for?

My friend claims her Mazda 3 won’t depreciate very much in the next few years, but that doesn’t sound right to me. From my understanding, every car depreciates a huge amount after even the first year of owning it! How much can we expect the Mazda 3 to depreciate?

I recently purchased a brand new Subaru Outback and I could not be more excited about it. In fact, I was so excited that I didn’t read the fine print of the warranty. Are oil changes included?
