What kind of oil should I add considering the best cost performance? The oil cap of my car is labeled as 87aki (r+m)/2 or 91ron. I don't remember what kind of oil I last added. Is it okay if I mix them if they are different ?

As long as you distinguish between diesel and gasoline for the rented car, I usually add 87 gasoline.
It's usually equipped with ordinary ones, after all, it's a rental car.
