Need help on an e60 oil change

Hi guys. Wondering what tool to buy to remove this oil filter cap
My buddy asked me to help him do an oil change because the dealer quoted him 180 just for an oil change.
I bough 7 quarts of 5w-30 synthetic oil and oil filter from the dealer with my BMWcca discount for total of 60 bucks.
I'm thinking a rubber strap wrench.

theres a oil cap socket (idk where to get it) that gets that off, otherwise you can fuck up the out side of the cap and make it a huge hassle down the road

I used an oil filter wrench with success. They arent on there tight or at least they shouldn't be torqued down past 30lbs.

Thanks guys.
The BMW tool part number is
83 30 0 493 396 oil filter tool
A quick google search finds that the size of the oil filter wrench would be a 86mm 16 flats.
Got this 86mm 16 flat for 6 bucks at pep boys.
