Here’s a cut and paste from your owner’s manual . . .
"It is also a good idea to check the engine oil level at each fuel fill. "
Anyways . . . your engine uses 0w20 synthetic engine oil, which needs to meet Dexos 1 specs
We have several hundred GM vehicles of various vintages in our fleet. Some older than yours, some newer
What I’ve noticed is that many of the newer ones which use 0w20 viscosity seem to need more engine oil added in between oil changes . . . versus the older ones which still called for 5w30 viscosity
I highly suggest you follow the advice that my fellow forum members have already given you . . . and which is in your owner’s manual
Every weekend I check the fluid levels of our family’s vehicles, in addition to checking tire pressures. I do this in the morning, before I head out to go shopping, fill up the tank, etc.
I keep the fluids stocked in my garage, so it’s just part of my routine
I buy engine oil on sale at Costco, and a pancake air compressor can be bought for a modest price at Home Depot, for example
