Protect Your MPG

With fuel prices on the rise, drivers are looking for ways to squeeze every last mile out of their tanks. While there is no magic bullet that will transform a car into a hypermiling champion, there are several simple tools and maintenance items that can help ensure it's operating at its original efficiency.

One of the easiest places to start is tire pressure. Underinflated tires create more rolling resistance, which means the engine has to work harder to move the car down the road. Even a few pounds per square inch below the manufacturer's recommended pressure can shave noticeable miles off a tank of fuel.

Keeping a portable tire inflator or compressor in the garage or trunk is one of the simplest ways to protect fuel economy. A quick pressure check every few weeks, especially as temperatures fluctuate, can keep tires rolling efficiently while also extending tread life and improving handling.

Another product that can help maintain efficiency is a fuel system cleaner . Over time, carbon deposits can build up in fuel injectors and intake components, which can disrupt the fine spray pattern that allows fuel to burn efficiently. These additives are designed to dissolve these deposits and keep the system operating smoothly.

Used periodically, they can help maintain proper combustion and throttle response. However, it's essential to note that these products are designed to restore or maintain efficiency, not exceed it. If your engine is already clean and healthy, you shouldn't expect dramatic gains in mileage.

Airflow is another crucial component of a vehicle's efficiency puzzle. A fresh air filter ensures the engine receives the clean air it needs to mix with fuel properly. When a filter becomes clogged with dust and debris, the engine has to work harder to pull in air, which can reduce efficiency and performance.

Replacing the air filter at recommended intervals is one of the most basic—and inexpensive—ways to keep a vehicle operating at peak efficiency. This simple maintenance task can make a noticeable difference in fuel economy over time.

Even small diagnostic tools can play a role in maintaining a vehicle's efficiency. Affordable OBD-II scanners allow owners to check for trouble codes or sensor issues that might affect engine performance and fuel delivery.

Catching these issues early can help keep the engine running at its most efficient, which is especially important when fuel prices are high. By addressing these simple maintenance tasks, drivers can make every tank of gas go a little further.
