Sinsull! What about back in the old days, they used to tell you to change your oil every 5000-7000 miles, and now they tell you every 3000? Mister says it's probably because the smaller engines need more frequent maintenance than the older, larger engines. But I dunno...

And once, a long time ago, I had a great pair of Adidas. I wore them for YEARS, and they never fully wore out, but they looked pretty crappy. Anyway, I went to buy another pair, and they had stopped making that style. The pair I bought wore out in a year. :-(
