The maintenance section over at Volvospeed.com has some information how to change oil, cabin filter and the plugs on a non-turbo 5 cyl which shouldn't be that much more difficult than the turbo. <P>Hopefully they'll have more maintenance info on the S80 and S60 soon. I just did the oil change on my S60 (My wife's S80 is due momentarily) and it's a snap, especially if you get the oil filter wrench from IPD.<P>Good luck.<P>
