It definitely burns (and leaks) some oil. At least 3 qts per oil change, maybe 4. It's hard to say exactly how much it's burning and how much is leaking. I do know that it seems to use more than my Turbocharged 4 cyl Ford with 100K more miles on it.

I use whatever oil is on sale. Everything from Advance Auto's brand (whatever that is) to Pennzoil, to Mobile. I'm more concerned with getting it changed on schedule than putting the best stuff in it.
I tend to avoild Fram filters - most often Advance Auto's or Motocraft.
Weight is usually 10-30 in the summer and 5-30 in the winter.
