How to Improve Your Car’s Fuel Efficiency


Improving your used vehicle's fuel efficiency is not just great for your wallet, it’s also better for the environment. Taking steps to reduce your environmental footprint is more important than ever and, in many cases, can be quite simple.

Learning how to improve your car’s fuel efficiency can involve booking more regular maintenance or adopting smarter driving habits. In this article, Race Auto Group will explore practical car fuel efficiency tips to help you get the most out of a full tank and limit your trips to the pump!

Regular Vehicle Maintenance

Proper, regularly scheduled vehicle maintenance is key to improving your car’s fuel efficiency. Whether you perform it yourself or trust the experts at Race Auto Group, a detailed maintenance routine will help boost your car’s performance and reduce emissions.

Engine Maintenance

We all know that a vehicle’s engine requires regular care to perform its best. It’s always best to schedule your maintenance check-ups and oil changes in advance and stick to a routine. Clean oil minimizes friction and wear, allowing the engine to operate smoothly and efficiently.

Oil filters should also be monitored, as an old, clogged filter will limit the flow of oil through the engine. This can not only impair your used car’s performance and burn more fuel but it can also contaminate your oil.

Tire Pressure

It can be surprising to learn that you can get better car fuel efficiency by maintaining something as simple as your tire pressure. Under-inflated tires create more resistance on the road. This can be better for grip in some situations but it also means your engine needs to work harder and use more fuel.

Regularly checking your tire pressure, including the spare in your trunk, can significantly improve your car’s mileage. Properly inflated tires can increase fuel efficiency by up to 3%!

Air Filters

Clean air is an essential part of the functioning of combustion engines. A clogged air filter restricts airflow, forcing the engine to use more energy and more fuel to get you where you need to go. By replacing a dirty air filter, you can improve car fuel efficiency by as much as 10%!

Check Your Gas Cap

A loose, damaged, or missing gas cap allows fuel to vaporize into the air. A tightly sealed cap in good condition will help prevent fuel loss and reduce emissions.

Driving Habits for Better Car Fuel Efficiency

Adopting the right driving habits can help get the most out of your gas money. Speeding can significantly increase fuel consumption, with efficiency typically diminishing rapidly at speeds above 80 kph.

By maintaining a lower speed and steady pace on the highway, you can notably reduce fuel usage. Using your car’s cruise control is a great way to maintain a constant speed and save fuel, especially over long distances and in flat terrain.

Don’t Let it Idle!

We’ve all sat in our car and let it run for a minute or two while waiting for someone. Next time, consider turning the engine off. Idling for long periods can use up to a half gallon of fuel per hour, depending on the engine size and whether the air conditioner is running. If you expect to be parked for more than a minute, it's more fuel-efficient to turn off the engine, as restarting the car uses less fuel than letting it idle for extended periods.

Air Conditioning vs. Windows Down

Using air conditioning at lower speeds can significantly reduce fuel efficiency; however, at higher speeds, the drag caused by open windows consumes more fuel than AC. So, if you're driving around town, roll the windows down and ejoy the weather. On the highway, get the A/C going for a comfortable, quiet ride and better car fuel efficiency.

Lighten Your Load

Every additional 100 pounds in your vehicle can reduce your kpg by about 1%. Remove unnecessary items from your trunk or backseat (except for emergency supplies or safety kits) whenever possible to improve fuel economy.

Frequently Asked Questions

Here are some answers to common questions about how to improve your car's fuel efficiency. If you want more information, we're here to help!

What is the best motor oil to use to improve my car's fuel efficiency?

Look for motor oil that is labeled as "Energy Conserving" on the API performance symbol. This oil contains friction-reducing additives that can improve fuel efficiency. Always use the grade of oil recommended by your vehicle manufacturer.

Can the use of my car’s electronics affect fuel efficiency?

Yes, minimizing the use of heavy electrical loads like high-powered sound systems, seat warmers, and excessive charging ports can reduce the load on the alternator and slightly improve fuel efficiency.

How can I tell if my air filter needs to be changed?

A visual inspection will show if the air filter is dirty or clogged. If it appears gray and is full of dust and debris, it's time for a replacement. A clean air filter can improve your car's efficiency and performance.
