It's not my car, it's not even a car it's a 16 ft rental truck that's been working hard for me through desert and mountains for a week now. It didn't give me a warning that oil was needed soon (that happened before I got it) instead it started flashing it needed oil immediately. It turned out to be 2k miles past due already (that's how far I had gone).

I had to go into their truck depot which was an annoying detour but it's all fixed now. They were super nice and it wasn't so bad really. But it was totally their fault, the place I picked up the truck had cleared the warning without replacing the oil.
