One piece of advise that my dad gave me when I first started driving was “It doesn’t cost any more to keep your tank full, than it does to keep it empty”.
This is the truth, and it’s something that I’ve always kept in the back of my mind. I do my best to never let my car go below 1/4 tank.
You never know when you might have to ride out a storm on the side of the road, or get stuck in traffic for an extended period of time, or if you have to outrun a hoard of zombies, having some extra gas in the tank never hurts, and it doesn’t cost a dime more to keep it on full, than it does on empty.
Totally agree about the zombies. Totally.
