What is the definition of Mileage Seeds?

Mileage seeds are like the hidden treasure maps of your car's fuel efficiency! They're the little nuggets of wisdom (or grime) you plant in your gas tank's memory, promising you more miles before you hit the dreaded gas station. Just imagine this: "My mileage seeds are whispering 'Eat more beans, watch more tires fade!' in the back seat of my car, making me wonder if I've been on a diet or just a fuel economy experiment gone wrong."
