How can I make my car more fuel efficient by adding modifications to it?
user
There are several ways to make your car more fuel efficient by adding modifications.  First, you can switch to a higher ratio gear, which will reduce the engine speed and improve the fuel efficiency. You can also install aerodynamic parts such as spoiler lip kits or front air dams, which will help reduce drag and improve gas mileage. An auxiliary oil cooler or smaller pulley for the crankshaft may also be added to further reduce engine load. A tuned exhaust system with flow-through muffler will increase torque, improve acceleration and increase fuel savings.
 
In summary, making your car more fuel efficient requires some knowledge of car engineering; however with the right tools and knowledge any driver can obtain impressive gas mileage with modified cars.

There are a few modifications you can make to your car to make it more fuel efficient. A fuel-efficient car uses as little fuel as possible to get the job done, and there are several ways to achieve this. An aerodynamic body kit, for example, can reduce drag and help your car cut through the air with less resistance. Eco-friendly tires are another option—they use new materials that roll more efficiently and reduce rolling resistance for better efficiency. Finally, a programmer or chip tunes the car’s computer system which allows you to adjust elements such as shift points and maximize torque curve in order to reduce your average driving RPM's thereby increasing fuel economy significantly.
