I checked the manual, which seems like it says that if not tracked, just follow the oil life monitoring system. Well that could be thousands of miles, is that really right? I checked the high-performance supplement and again, if not tracked, it appears that it points me back to the normal manual.

So, from GM's perspective, at what interval should I do my first oil change and what about the rear diff on the convertible? Isn't it different? Does it need anything different?

I realize there are a lot of opinions on this, but am I correct that GM doesn't feel that a non-tracked ZL1 needs anything different from what the life monitoring system says?

Your first oil change is free at any dealer if you bought it new.
