Account for aerodynamic dragAerodynamic drag can have a significant effect on your pickup's fuel efficiency. To reduce its impact, consider investing in the right accessories for your pickup and removing any that may increase the drag. For instance, you can mount a roof spoiler, also known as a roof wing, on the roof to produce greater downforce. A roof spoiler helps increase the stability of the vehicle, which, in turn, improves fuel efficiency, especially when you're driving at high speeds. Keep in mind that while mounting a roof spoiler is fairly easy, it's important that it's placed at the right height to maximize your pickup's fuel efficiency. If you're uncertain about the best height for the roof spoiler, it's best to have the installation done at a service center or workshop. Conversely, some accessories, like the extra lights that you may have installed for added safety or the top bars or racks that you may be using to carry additional loads, can increase aerodynamic drag. While these accessories may come in handy from time to time, it's best to evaluate how often you use them and whether the trade-off in terms of fuel efficiency is worth it. Reducing the vehicle load by offloading any unnecessary cargo is another great way to reduce aerodynamic drag. While many pickup owners exclusively use their vehicles to tow or haul heavy loads, it's best to check from time to time if you have additional heavy cargo in the truck bed that you really don't need.
