What should i use for oil?

Does anybody know if it's supposed to rain this weekend?

I was wondering how long it would take for Regal to jump in the mix. Now if only I could source a little popcorn...

I just bought a new 2009 DR-z400S and have the same question. The dealership says I should only use Suzuki brand 10-40W conventional until 5000 miles and no synthetics until after 5000. The manual recommends oil changes at 4000 mile intervals. That seems long to me. How often do people here go between changes? What brand oill filters are recommended. I use K&N oil filters.
