Change Engine Oil on 2007 Volvo XC90

Change the oil yourself--no hassle with dealer, no waiting for quick lube place to find the filter (no one ever has it in the shop).

Steps

Obtain the filter (NAPA part #7806), disposable crush washer for the drain plug, 36 mm oil filter housing socket (specifically for this application--auto parts store will know what you need), and oil (according to your climate needs, in your owner's manual).
You will need a catch pan for the oil as well (at least 8 qt capacity).
Engine is covered with a plastic cover that simply pops off. Remove it.
Jack the front end of the car, CHOCK THE WHEELS, and put jack stands under the frame. Safety first!
Loosen filter housing with 36 mm socket. The housing is on the passenger side of the engine (accessed from above), about a foot down and just next to the dipstick tube. This part may take some muscle.
Place drain pan under oil drain plug under the car and remove plug with 1 in. socket. Allow oil to drain out fully.
Replace oil drain plug with NEW crush washer, then tighten drain plug down. Lower car from jack stands carefully.
Place new filter in housing, replace O-ring on filter housing with the new one which should have come with the new filter. Lubricate the O-ring with fresh oil.
Tighten filter housing down. It's supposed to be torqued down but you may not be able to squeeze your torque wrench into the available space.
Pour in {{safesubst:#invoke:convert|convert}} fresh oil through usual route.
Replace plastic engine cover.

It is kind of an expense to get the equipment (jack stands, oil catch pan, filter housing socket etc.), but in the long run it saves a lot of time and money to do this yourself in your garage.
