I have a 2019 Kia Sorento SX (3.3L V6). The last time I took it to the dealer (Dec '22) I gave them 2x5qt bottles of M1 Advanced Full Synthetic 5w-30 and asked them to use it when changing the oil. When I returned back to my place (about 40 minutes away) I noticed that they only used one bottle, and the second was left unnused. Upon consulting the manual, the car takes 6.87qt. I had to go to a nearby home depot to purchase a funnel and I manually topped off the car with the remaining amount from the second bottle (about 1.8 qts).
There was no low engine oil light during this time. Should I be concerned about any potential damage? I emailed the dealer's service department to keep this incident on record, naturally he tried to gaslight me when I spoke on the phone (he was asking if the low engine light came on, and that "5qt should be ok" or something of that nature).
I am planning to conduct a UOA upon my next oil change, which is scheduled this coming week at a different dealership.
Thoughts welcome.
Edit: I did add another approx 0.5 qts when I noticed that the dipstick level was no longer at F (this was about 4K miles into the OCI - about 1 month ago, now I'm at 5.5K miles).
