A buddy of mine in high school got a brand new car from his dad. He had no idea you had to change the oil in the car. So we were driving up to a tournament in Canada and the engine starts knocking and we pull over. I pop the hood and i'm like this thing is like a year old what have you been doing to this thing? He'd put like 30k miles on it in a year cause he drove everywhere. I jokingly asked him when the last time he changed the oil was and he's like what do you mean? thing was totalled.
