remove the bottom splash gaurd-black plastic bottom cover.

oil filter is easy to get to and change- i only use volvo oil filters. they are made by Mann. on passenger side of car. tighten the filter hand tight then 1/2 turn to make snug does require a oil filter wrench to tighten.

oil since my car is a turbo i use mobil 1 5-50w red cap
non turbo then you can use a 10-40w synthetic or synthetic blend is good.

drain plug is on back of oil pan, there is a copper or aluminum crush washer that must be changed. get it from volvo.

tourque on oil drain?? i do not remember but do not overtighten it since the pan is aluminum it can be stripped out. make it snug than just a little more to tighten- 1/2 turn maybe that is all it takes

easy to do, takes about 15 minutes to remove cover, drain oil and change filter.

the hardest part is jacking up the car.
