On my 2.6 I have to put about 6 litres in to bring to max on dip stick?
Cartridge filter holds more oil than spin on... Other variables include oil temp when drained and how long it's left to drain for... I suspect that Nick refits the sump plug when the trickle stops.
No, I remove the drain plug first, change all 6 plugs, both filters, top up coolant and anti-freeze, deal with any issues and
then fit the plug and add the oil. 5 litres fills it to just below the max mark, which is good for a year and about 10k miles. After 8 years of doing this, I just pour in the whole can and go and do something important.
There's a slight dent in the steel sump, but I doubt that accounts for the 0.75l that it's 'missing'.
