8 Factors Affecting Your Fuel Efficiency You Might Not Know About.

Fuel efficiency is a hot topic these days, and for good reason. Gas prices constantly fluctuate, and people are increasingly aware of their environmental impact. It’s more important than ever to ensure vehicles run as efficiently as possible. 

You’re probably aware of the basic tips for improving fuel economy, such as avoiding aggressive driving and keeping your engine serviced. What about the factors you don’t know about? Here are eight surprising elements that could affect your fuel consumption without realizing it. 

1. Underinflated Tires

You’ve probably heard that keeping your tires properly inflated can help improve fuel efficiency, but do you know just how much of an impact underinflated tires can have? Your vehicle’s

for every one psi drop in tire pressure. That might not sound like much, but it can add up over time.

Ensure your tires are always properly inflated by checking the pressure at least once a month using a reliable gauge. Do this when your tires are cold, as driving can cause the pressure to increase. Remember to check your spare tire as well.

2. Worn Leaf Springs

Worn leaf springs are another crucial factor negatively affecting your car’s fuel efficiency. These springs are a vital part of your vehicle’s suspension system. When they become worn or damaged, they can cause your vehicle to bounce and sway more than usual. This extra movement requires more energy, which in turn burns more fuel.

To check on the condition of your leaf springs, try the simple bounce test. Push down on the front of your vehicle and release. If it bounces more than twice, it’s a sign you should replace your spring. 

You can also check the spring deflection to ensure it’s within the proper range. The deflection limit definition for the load on linear springs comes down to a simple formula. Just

of the spring. For instance, if you have a 12-inch linear spring with a 200-pound-per-inch deflection rate, your deflection limit would be 2,400 pounds.  

3. Poor Aerodynamics

Your vehicle’s aerodynamics is another factor that can significantly impact your fuel efficiency. The more aerodynamic your car is, the less resistance it faces as it moves through the air. This means your engines don’t have to work as hard to maintain speed. Conversely, a vehicle with poor aerodynamics will require more fuel to overcome the increased drag.

There are several ways to improve your car’s aerodynamics, such as lowering its ride height, adding a front air dam or rear spoiler, and keeping your windows and sunroof closed at high speeds. Even small changes, like removing unnecessary exterior accessories or keeping your car clean and waxed, can help reduce drag and improve fuel efficiency.

4. Excessive Idling

You know what it’s like to be stuck in traffic or waiting in a long drive-thru line with your engine running and nothing to do but wait. While it might not seem like a big deal,

your fuel economy. Your motor is running but your vehicle isn’t moving, meaning you’re burning fuel without going anywhere. 

One simple solution is to turn off your engine if you anticipate stopping for over a minute. If you have a newer vehicle, it might come with automatic start-stop technology, which can help reduce fuel consumption during idling.

5. Roof Racks and Cargo Boxes

If you love outdoor adventures and often transport extra gear, you might have invested in a roof rack or cargo box. While these accessories are incredibly convenient, they can also significantly impact your vehicle’s fuel efficiency. They increase your car’s wind resistance, meaning your engine has to work ******* to maintain speed.

How much of an impact can these accessories have? One study found that a roof rack can

at highway speeds. To minimize the effect on fuel efficiency, try removing your roof rack or cargo box when you’re not using it.

6. Using the Wrong Motor Oil

Did you know using the wrong motor oil can hurt your fuel efficiency? It’s responsible for cooling, lubricating and cleaning your engine, but using the wrong type can cause it to work ******* than needed. The extra effort translates to reduced fuel efficiency and potential damage to your engine over time,

Ensure you’re using the right motor oil for your vehicle by consulting your owner’s manual or asking your mechanic for recommendations. Pay attention to the oil’s viscosity, which is its resistance to flow. Using oil with the wrong viscosity can increase friction and reduce fuel efficiency. 

7. Poorly Maintained Fuel Injectors

Fuel injectors deliver fuel to your engine in a precise, controlled manner. They can’t perform this task as efficiently when they become clogged or ******, reducing fuel economy. In some cases, poorly maintained fuel injectors can cause your engine to misfire or run roughly, further reducing efficiency and potentially causing damage. 

Use a fuel injector cleaner periodically to keep things in top shape. These cleaners are designed to remove built-up deposits and restore the injectors to their original performance. You can also help prevent clogging by using high-quality gasoline and avoiding letting your tank run too low, which can cause sediment to be drawn into the fuel system. 

8. Ignoring the Check Engine Light

Almost everyone has been guilty of ignoring the check engine light at one point, but did you know that doing so can hurt your fuel efficiency? When the check engine light comes on, it’s your vehicle’s way of telling you something isn’t right. The issue is often related

, which can directly impact fuel economy.

If your check engine light is on, don’t ignore it. Take your vehicle to a mechanic as soon as possible to have the issue diagnosed and repaired. Sometimes, a simple fix like replacing a faulty oxygen sensor can significantly improve fuel efficiency.

Boost Your Fuel Efficiency

Many factors can affect your vehicle’s fuel efficiency beyond the obvious ones, like driving habits and tire pressure. Be aware of these often-overlooked elements to optimize your car’s performance and save money at the pump. With some extra care and attention, you can enjoy better fuel economy and do your part to reduce your environmental impact.
