Yeah I know how to change oil, i used to work in a lube bay way back in the day, just a hassle to buy everything and I don't have much room to store this stuff.
Called a shop and it'll be $158 for an oil change.

if I do decide to do it myself, do we have to use a certain BMW-Approved Oil? Canadian Tire?
(this is the first time in awhile I actually care about what I put into my vehicle haha)
