Hot or Cold Oil drainage?

[9hellheaven]

This is a quicky..My 997 has been tucked up since November and I want to drop the oil/filter this month. Shall I do it cold as its showing being slightly over full on the dash read out, I assume because all the oil is in the sump now. Or shall I warm her up and then drain? Is it to straight forward to think that all the oil in the sump now (cold) = any metal fillings etc in the sump/filter also, so do it while cold??
Any thought? I want to rip the filter and check the oil for any lurking nasties..Thanks guys

Hi

HOT....then it ALL comes out easily...and leave it to drain for as long as possible...

All the best Brett

Send it to the OPC for a simple job like this. When i supplied my own oil the bill came to a mere 50 squid.

If you do prefer to do it yourself, don't forget to purchase a replacement copper crush washer and torque to the correct amount.

The system holds 9.5 litres but only takes 7 and 3 quarters when refilling if you also change the filter.

So which ever way you do it, 1 - 2 litres is staying in the system anyway.

You are only changing 75% of the oil.

Thanks atm I didnt know that! Where does the other two litres hide then?
I will fill with 6 litres and use the dash read out to top up. I am going to drain it overnight, it does seem odd that a full change is not possible. Maybe a flush Oil? Maybe not?.
Thanks anyway everyone..

Fill with 5 and then check the display cold. Top up half a litre at a time. Putting it in is far easier than getting it out.

With the filter change I just put all 8 litres in. Now my dash display does show me as over filled. Engine been running fine with no smoke or misfiring.
