Best to get it up on a 4 poster ramp if you can then remove under cover and then locate sump plug and remove and drain oil then remove oil filter,once all oil has drained replace sump plug and new oil filter but remember to fill it up first then replace under cover and drop car down to a level standing and fill up with fresh oil usually around 5 litres,turn engine over using a socket on the crank pulley to ensure the sump is full then let the engine run for a few mins b4 stopping and checking level, thats what i do anyway
