Draining the oil cooler

[Thefunk]

So far I've done two oil changes on my Z and haven't drained the cooler. I'm concerned with mixing fresh oil with spent oil. How do you folks drain the cooler?

I like Ammo NYC / Larry's content. He bought a 992 GT3 in late 2024. It takes 8.1 liters of oil for a rebuild. BUT, there are so many low spots, coolers, dips, etc that an oil change only drains 4.1 liters of oil!

Larry and the mechanic's reactions:

@Mugzilla do you drain the oil cooler on your Z?

No. Even if it was easy, I'd be worried about leaving a failure point. That leftover oil is negligible.

Just change your oil every 3k miles
