Billarf, I have updated post 1 with the new "crush washer" instruction. I wasn't 100% but I never had any issues using the washer the way I did. But since you've mentioned that your way is the correct way, I'll stand corrected.
So, I have been really busy and haven't posted my 6th oil change. Everything is basically the same. Drive the car, bring the temp up to 210+, get oil sample, change the oil, new oil filter/oil etc. Here are some pics:
Safety first. ALWAYS wear goggles.
As you can see it's been a while! Car had Blizzaks and there's snow outside.
Draining
Iron particles trapped on the magnet.
The filter is fully lubricated with oil and it's 1/4 -1/2 filled with oil to prevent dry start.
Installed.
lol I'm still waiting for the Advertisement check from Aquafina!
My Z actually has 35xxx miles now. So, I put about 31,500+ miles on the Z with Redline oil. I experience has been nothing but fantastic. Hopefully it continues this way.
