Closing windows opens new paths
Keeping your car windows closed on the highway reduces wind resistance and improves fuel efficiency.
By closing the windows, you reduce wind resistance, which means the engine does not have to work as hard to maintain speed.
In addition, using the air conditioner instead of opening the windows at high speeds can be more fuel efficient. Less wind resistance means your car can move more easily and use less fuel. For optimum performance, use Shell V-Power NiTRO+, a fuel designed to protect and improve engine efficiency. Switch to Shell gasoline for superior care of your car.
