There were many studies which have shown that the rooftop carrier of the car is in a direct relation with the miles per gallon of the same. Same like the study which stated that driving with closed windows is giving better MPG than the drive with the open windows of the car. Now the scientists get to explain this theory about the carrier and you will need to find the fit for you, either carrying a lot of luggage or driving more miles. It will be the main thing to think about before going on a long road trip.

The rooftop carrier is going to be mounted on the car if the trunk is not big enough for the owner. This is the case where the whole family is going on a vacation far away from home and there are three girls in it. The girls will take all the clothes from the closet and then the rooftop carrier is the best solution. And the driver is going to pay the price for all that luxury for them. There will be a 0.8 percent more fuel spent on the road trip and if it is a really long one then he will feel it on the wallet.

This number is reflecting on the global, worldwide MPG ratio. There are the 400 million liters more fuel spent by the cars that are wearing the rooftop carrier. It seems a lot of fuel and if we continue to buy them and mount them on our beautiful rides than the fuel shortage will become even closer than it is now.

If the 0.8% is the number that doesn’t mean anything to you than you can go on that long desired vacation with no problem and you can take anything that you like inside it.
