I have not contacted Ms Adelson. Do you have an email address for her?
I got the build date by sending an email with my vin number to
socialmedia@gm.com. I did this to get a plaque made by Chris Frech.
I'm just about to hit 17,000 miles on my ZL1. Oil pump is original. No concerns. I did switch to Mobil 1 0W 40 Dexos 2 in the summer of 2018 and have stuck with it ever since.
Engine is stock except for a Green drop-in filter and removal of the rain/snow blocker in front of the air intake tract.
Driving habits have not change since I bought the car. I don't track or street race it but I don't baby it either.
Only engine issue was a bad bearing in the supercharger idler pulley that showed up in 2018. Pulley was replaced under warranty. Otherwise, knock on wood, my ZL1 has been trouble free. I just replaced the battery in May. I was shocked to get almost seven trouble-free years from the OEM battery.
