Put a litre of fresh oil in for a flush and got even more back? Didn't measure what I put in but felt like I got more back.
Pulled the sump plug and got nothing.
Topped up with 5.9 Litres and showed just under top of full scale.

Conclusion:

1. The extraction pump method gets it all
2. I am consuming oil. Was about 15,000 ks since last service (not ideal I agree) and mainly city driving.

Have been running 5W-40 Penrite. Do I need to be concerned with this consumption?

Yes. That’s very heavy consumption. I lose about 1/2L in 10,000km on my D4 3L and it last at 380,000km.

Personally I wouldn’t be concerned with the consumption but I would be very concerned that I had failed to check the levels every now and then and that I had let it get so low and it had been running low for who knows how long
just check your oil levels every 1000 to 1500km and top up as required

Yeah good point. The lack of checking is worse. My old Golf GTi uses about a litre every couple of thousand km. It’s like - refuel - re-oil. It’s not like there are oil clouds out the back either. Those engines are known for heavy oil use.
