Half of a Tank

I got my first car and I was driving around the city. It had excellent mileage, and my father stated, “Never let your gas tank go below a half tank. At half a tank, always fill up.” No biggie, I can do that. And he proceeds to share with me that when you run your car on empty or it gets deficient, sludge will begin to get kicked up, and it will land in various parts of the vehicle, which will only cause you much trouble in the future. As well, if I ever ended up traveling away from home or got lost in the city, I would undoubtedly have more than enough to not only find my way back home, but if necessary, find my way to the next gas station.

I’ve never tested his advice to see how low I could go. At half a tank, I fill up every time.

What’s a piece of advice that you’ve given your daughter that she is still using today?
