you also need a sump plug as they aren't re-usable
you'll also require a torque wrench as the sump plug should be tightened to 30Nm
oil change, run engine for 10 mins at idle till the oil is at temp
turn off engine, jack up car (use axle stands), remove sump plug, drain oil, remove oil filter cap, change oil filter (this will have a side marked top, this is the top), change oil filter o rings (lube with some oil) replace cap. replace sump plug.
fill the engine to the line on dip stick, about 5 litres, run engine for 5 minutes, check for leeks, check oil level, top up if needed.
