Well, i went ahead and changed it at 5000K. I also lubed it - which I've been doing every 10000-15000K. The reason I asked is the price of oil & filters here is outrageous. $18 for the filter, which I guess isn't too bad, but $6-7 liter for oil?

But I did try something new. I took off the filter with the engine cold. I wrapped a plastic bag around it and no mess. About a cup of oil or less drained from the filter so I figure no big deal on the same amount of old oil still in the system after the change.
