At my local gas station this morning, regular gas was selling for $1.24/L and premium was 14¢ more expensive at $1.36/L. That's a whopping $8.40 difference if I were to fill my 60L tank. Not as much as I expected actually, but I will be putting regular gas in my car anyways. So why spend the extra $8?
We've all had this experience one time or another: you're late for an appointment and realize that your gas tank is no empty, rather than taking the time to fill it up you just put enough to hold you over. For some of us this is more than just a rare occurence...for some, it's the method we use at the pumps every time we visit them.
Which brings us to our question: Should you always fill your gas tank full rather than adding just a little each time we visit the pump?
