MIAMI – Those cute reindeer antlers you put on your car windows during the holiday season will put a lump of coal in your next gas bill.

USA Today reports the aerodynamic drag caused by the antlers have a negative effect on gas mileage.

According to the report, a General Motors test found the antlers created a 1-mile-per-gallon decrease in highway fuel efficiency.

Having a Rudolph nose on your vehicle also adds to the drag.

Also, make sure you buy a Christmas tree from a nearby lot as a tree tied to the roof of a vehicle creates a 30% decrease in fuel efficiency.
