It will be 100% fine. With no direct injection, and all highway, it's pretty easy on the oil. Have you ever bought a used car with some higher mileage from the 2nd, or 3rd owner? It likely had an oil change or 4 missed...I forgot to mention it has a Fram Orange Can (FOC, pronounced "fawk") on it with the Kirkland oil rated for 10k on the box. Does this change your view?
I would make the level is still good, and if its half a quart low, pour in a half quart of any engine oil you have around to make you feel better.
My poor old Focus would burn almost 2 quarts per 10-12k mile OCI in the last couple years, so it got a quart of rotella 15W40, because I wasn't opening a jug of the good stuff to just run it for 1-2k until I changed it.
