- coolant or water if your car overheats (coolant is preferable cause it won’t hurt the engine in the long run but hey i know money is tight)

- flashlight in case you break down at night and need to check under the hood and your phone is dead

- SPARE TIRE. Know how to change a tire!

- Jumper cables. you will at some point leave your lights on. you just will.

- AAA or any other road side service is never a bad investment. (try to mooch off your parents as long as you can though)

- keep oil made for your car in your car

- when it's cold outside, especially if there's snow, keep sleeping bags and boots in the car in case you break down
