The day after picking up the car, I was reminded to add engine oil. I contacted customer service and was told to go to a nearby Hertz branch to add oil. After driving over ten miles to find one Hertz branch, it turned out to be closed. The next day, Saturday, I drove another ten miles to a city branch marked on Google Maps, only to find it had been shut down. Then I drove another ten kilometers to another location, which had also been closed. Finally, after driving another ten kilometers, I found a Hertz branch that was actually open. After explaining the situation to the staff, they pulled up the vehicle information and confirmed that the oil indeed needed refilling. However, they couldn’t help me add the oil and suggested I return to the rental location to exchange the car. Luckily, I had only rented the car for four days, so I didn’t plan to drive to many places anyway. I decided to wait until the fourth day to return the car as scheduled due to the hassle of driving around just for the oil.
