Great choice on a new car. They put the Volt on that same Cruze platform and charge $35000 for it, so you got the best deal getting the non-plugin, non-hybrid version of the Volt here.

Good plan. Here is why: Change out the factory fill at around 1,000 miles to get the junk out. We see high levels of iron particles in factory-fill UOA's all the time here. Getting it out is likely good. ........The 0w20 spec in the owners manual is really for cold start protection & CAFE MPG for GM. 0w20 does work best in the winter, yet summer you could go up slightly in viscosity (and its not much, only 15% in HTHS) and its actually good to do. Note some other makes actually say "higher viscosity in warm weather" (Hyundai, Subaru, etc.) in their owners manual.
I doubt GM would ever deny an engine warranty claim since you use M1 5w30 in the summer only; its an oil brand they back in the owners manual.
I got one dealer oil change at the standard 7500 miles (OLM did it) on an '18 Equinox 1.5T, and they over-filled just a bit, probably no big deal since there was no foam or bubbles on the dipstick, but they did put on an oversized oil filter like I asked.
Your Cruze uses the same oil filter that my 1.5T & Corvettes use, a PF64, yet you can upgrade to a Wix WL10255 (oversized, it should fit your engine, not sure so check for about an inch more length room).
Choosing Wix here due to its correct bypass pressure setting, as GM is particular about that, and Wix filters well, silicone ADBV etc. (I normally recommend Fram Ultra but it doesn't have the right bypass pressure.)
If you don't have room for an extra long WL10255, then a standard PF64-length WL10290 will work fine.
