I have a non-DI version of the same engine in my Kia, 5K OCI works pretty good on dino for me on UOA results although I'm running synthetic at the moment because I got it cheap.
My driving regimen is 75% short trip, 2.2 miles to work and back. Your daughter's car can probably do the full 7500 if she is driving 30K a year, I'm guessing a lot of highway mileage. I'm only doing about 8-10K a year these days.
On these cars the approved oils are 5w20, 5w30 and 10w30 above 0F. I would do UOA and if 5w20 is doing ok, extend. But if there's too much dilution with the DI I would start with 5w30 if you are intending on running full 7500 OCI.
Also I agree to get the OEM filter. I have not found an aftermarket filter that doesn't cause more startup noise than the OEM filter.
