Mine does not use oil at all (27K miles driven now since november 2000) and I do an oil change every 6 months. We only had to recharge the AC this week but we're using it a lot (300 sunny days a year here) and we just had day 13 in a row with temperatures above 90 degrees F. So, that is not a surprise to me that the AC needed a 'refill'.!
I just wish it would have more cupholders (like the newer one) - I would then be able to drive more often thru the drive-trhu to get drinks without cleaning up.

- Just kidding! I heard the newer version has 18 cupholders or so.
