Good grief, just how tight can you get the oil filter cup screwed onto
its mounting base?  Got the 2004 XC90 serviced for the 60K mile mark a
few months back.  It is ready for an oil change and getting that oil
filter cup off is just not happening.  

After dropping the under carriage cover to access the oil drain, what
do I find looking at me?  I see one transmission cover plate bolt
laying on the under carriage cover and two other bolts are backed out
of their torque positions.  Not happy when I found that.  I do not
think that is something that occurred by itself.  

I got the specs for the pan to re-torque the bolts.  Then comes the
oil filter cup, it just isn't moving.  I will have to get a heavier
duty cup tool to spin that thing off, two I did have, and ruined, were
not at all that durable, just stamped steel, 3/8 drive.  I hate to
think I might  have to use my impact wrench.  I never screwed that
think on as tight as the mechanic did during the 60K checkup.

This is my first vehicle with a oil filter cup, I question the thought
on that.
