Car modifications usually improve car performance at the expense of fuel economy. For example, increasing your car's ground clearance may improve its handling over rough terrain, but it may increase its fuel consumption. However, there are also modifications that improve fuel efficiency. Here are three examples of such modifications.

Pickup Truck Caps

The open bed of a pickup truck is useful for hauling cargo, but it does this at the expense of reduced fuel efficiency. This happens because the bed interferes with the aerodynamics of the truck and increases wind drag on it. As a result, the engine has to work extra hard (meaning it has to use more fuel).

When you install the truck caps, you improve the aerodynamics and make the airflow over the truck smoother than before. Consult your mechanic to help you choose a cap design that will give you maximum fuel savings.

Fuel Efficiency Monitors

These monitors will not increase your fuel efficiency automatically, but you can use them to reduce fuel consumption consciously. Like most drivers, you have probably been trying different ways of driving, braking, and acceleration to boost your fuel mileage. However, it can be difficult to know what works and what doesn't. By installing these monitors, you can tell how much fuel your car is using at any given time. Use the monitor's readings to improve your driving, and your fuel economy will improve too.

Quality Electrical Cables

Your car's electrical system plays an integral role in its fuel efficiency. The electrical system, which includes things such as the air conditioning unit, entertainment system, and lights, are powered by the alternator when the car is running. The alternator is powered by the engine, which means that these electrical systems will be using fuel when your car is running.

Loose, damaged or worn out electrical cables increases electrical resistance and make your car's engine work harder to produce the necessary power. Therefore, replacing your car's electrical cables with high-quality ones that do not wear out fast is a good way to improve fuel efficiency. Consult a local mechanic (such as one from Knoll Automotive Services) for advice on the major cables that you need to focus on.

Always understand the pros and cons of a modification before going ahead with the installation. Also, it's good to work with an experienced mechanic to help you choose the best option available for every modification you wish to make. For example, heavy pickup truck caps can add weight to your car and minimize the effect of the improved aerodynamics on your car's fuel efficiency; your mechanic can help you choose a light cap.
