From the 2017 ZL1 manual:
"Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system that indicates when to change the engine oil and filter. This is based on a combination of factors which include engine revolutions, engine temperature, and miles driven. Based on driving conditions, the mileage at which an oil change is indicated can vary considerably."

The Manual also specifies a break on oil at 1500m, and the performance supplement specifies a change at 500m.
