DO NOT FOLLOW JAMES" INSTRUCTIONS TO THE LETTER !!!!!!!
Follow exactly as he states except for the adding oil part !. James, I am sure means fil the filter with 1/2 litre of oil, then refit. Then having re fitted the sump plug, add the oil to the engine, Usually around 4 to five ltres !, check the level on the dip stick, then run the engine, and turn off, wait about a minute for oil o settle, then top up as necessary.
