Sure, cleaning out your car makes it more pleasant to drive, but it can also improve your gas mileage. Removing 100 pounds (45.4 kilograms) of weight from your car gives it a fuel economy boost of 1 to 2 percent. That might sound like a lot of extra weight, but many of us use our cars' trunks as storage spaces. Are you stashing your golf clubs or a stroller in your trunk? Pulling those things out and toting them only when you need them can help improve your miles per gallon with very little effort.
Auto makers are taking weight very seriously, striving to build lighter, more fuel-efficient cars. By replacing bulkier metals with lighter-weight ones like aluminum, they can improve mileage by as much as 10 percent without making any other changes to the design or the engine.
Cleaning out your car is just the beginning. Check out how proper maintenance can help improve your fuel economy.
