Weight is the enemy of fuel economy. Everyone here knows this makes sense.
Some of us in the area carry a bunch of unnecessary weight, and I'm not talkin' what you see in the mirror.
Guys; sports equipment and tools. Ladies; well, just take a look around the passenger compartment and trunk. I think my car has about forty-five pounds of French fries on the floor.
All that extra weight wastes gas as you drive between here and there, and everywhere else in between.
Lose the junk and save some money.
...And you really only need one of those spare tires.
