How Can You Increase the Fuel Efficiency of a Kia Soul without Compromising Performance?

Fuel efficiency is a major consideration for any vehicle owner, and the Kia Soul is no exception. Buying a car is not just about the initial purchase cost. Running costs, particularly fuel, are also a significant factor. You might wonder if there’s a way to make your Kia Soul more fuel-efficient without compromising its performance? The answer is yes. In this article, we’ll explore various methods to increase the fuel efficiency of your Kia Soul and maintain its power and responsiveness on the road.

Understanding Fuel Efficiency Factors

Before we delve into specific tips and tricks, let’s explore what affects a car’s fuel efficiency. There are several factors at play when considering a vehicle’s miles per gallon (mpg) performance, such as the engine type, driving habits, and the car’s overall condition.

One key factor is the vehicle’s engine. The Kia Soul comes with either a 1.6L or a 2.0L inline-four engine, both of which provide good balance of power and economy. However, how you maintain and use this engine will significantly impact its mpg.

On the other hand, your driving habits can also affect fuel efficiency. Aggressive driving, such as rapid acceleration and braking, can drastically reduce your car’s mpg. Likewise, excessive idling, driving at high speeds, and carrying unnecessary weight can lower fuel economy.

Finally, regular maintenance of your vehicle is crucial. A poorly maintained car will consume more fuel and perform less efficiently on the road.

Keep Your Engine in Top Condition

A well-maintained engine is a fuel-efficient one. Regular maintenance will not only extend the lifespan of your car but also improve its fuel economy.

Tune-ups are key to engine maintenance. For a Kia Soul, the manufacturer recommends a tune-up every 30,000 miles. A tune-up includes checking the spark plugs, replacing the air and fuel filters, and inspecting the engine’s belts and hoses.

Moreover, regularly checking and replacing your vehicle’s engine oil is crucial. Old, dirty oil can cause friction in the engine, reducing its efficiency and thus increasing fuel consumption. Kia recommends changing the oil every 7,500 miles, but this may vary depending on your driving habits and conditions.

Adopt Eco-Driving Habits

Eco-driving is a method of driving that maximizes fuel efficiency. It involves a series of techniques that will not only save fuel but also reduce wear and tear on your vehicle.

One such technique is smooth driving. By avoiding sudden starts and stops, you can significantly reduce fuel consumption. The Kia Soul’s manual transmission offers the driver better control over the vehicle’s speed and acceleration, facilitating smooth driving.

Another eco-driving technique is to reduce idle time. Letting your car idle for long periods wastes a significant amount of fuel. If you’re waiting for more than a minute, it’s best to turn off the engine.

Utilize Your Kia Soul’s Fuel-Saving Features

Kia has engineered several features into the Soul to help you drive more efficiently. Understanding these features and utilizing them properly can make a huge difference in your fuel consumption.

One such feature is the ECO mode. When activated, it adjusts the engine and transmission to optimize fuel consumption. It may slightly decrease the vehicle’s responsiveness, but the improved mpg is well worth it.

Another excellent feature is cruise control, which maintains a steady speed and reduces fuel use. However, it’s best to use it on long, straight stretches of road, as constant adjustments in speed on hilly or winding roads can increase fuel consumption.

The Kia Soul also comes with a real-time fuel consumption display. This feature allows you to monitor your fuel economy as you drive, providing instant feedback on your driving habits.

Choose the Right Fuel for Your Vehicle

The type of fuel you use can also affect your car’s performance and fuel efficiency. Kia recommends using unleaded gasoline with an octane rating of 87 or higher for the Soul.

While it may be tempting to go for the cheaper, lower-octane gas, it’s not always the best choice for your vehicle. Higher octane fuel can make your engine perform better and thus improve fuel efficiency.

Just as importantly, avoid using E85 or other ethanol-based fuels. Although they may be more environmentally friendly, they can decrease your vehicle’s fuel efficiency and potentially cause damage to the engine in the long run.

In conclusion, improving the fuel efficiency of your Kia Soul is a multi-faceted approach involving regular maintenance, adopting eco-driving habits, utilizing the car’s built-in features, and using the right fuel. By following these steps, you can enjoy the best of both worlds: an economical ride that delivers the power and performance you need.

Remember, every little bit helps. Even small changes in your driving habits or routine maintenance can lead to significant savings in fuel cost over time. So, why not start today and make your Kia Soul a more fuel-efficient vehicle without compromising on performance?

Regular Maintenance: The Key to Fuel Efficiency

Regular vehicle maintenance is fundamental in maintaining your Kia Soul’s fuel efficiency and ensuring optimal performance. Poor maintenance can significantly increase your fuel consumption. Kia Soul, like other Kia models such as the Kia Niro, Kia Forte, and Kia Telluride, is designed with high-quality parts, but these parts require proper care to function efficiently.

Essential maintenance includes checking and changing the oil regularly. Dirty engine oil can cause friction, which not only damages the engine but also reduces fuel mileage. Kia recommends changing the engine oil every 7,500 miles, but it is advisable to check your oil levels frequently, especially if you often drive in heavy traffic or harsh weather conditions.

Regular tune-ups are also crucial. They involve checking and replacing the spark plugs, inspecting the car’s belts and hoses, and replacing the air and fuel filters. These parts play a significant role in maintaining your Kia Soul’s fuel efficiency. For example, a clogged air filter can reduce fuel mileage by up to 10%. Therefore, periodically changing the air filter can help ensure a smoother and more fuel-efficient driving experience.

Keeping your tires properly inflated is another simple yet effective way to improve your fuel economy. Under-inflated tires can cause your car to use more energy to move, thereby burning more fuel. It’s recommended to check your tire pressure at least once a month and before long trips.

The Impact of Driving Habits on Fuel Efficiency

Your driving habits significantly influence your Kia Soul’s fuel economy. By adopting eco-driving habits, you can maximize your fuel efficiency without compromising on performance.

One eco-driving habit is gradual acceleration and deceleration. Rapid acceleration or hard braking can use more fuel. Driving smoothly allows your vehicle to maintain a steady momentum, thus conserving fuel. If your Kia Soul has a manual transmission, utilize it effectively to control your speed and acceleration.

Reducing idle time is another way to improve gas mileage. Idling consumes fuel while contributing nothing to your journey. If you’re waiting in your car for more than a minute, it’s more fuel-efficient to turn off the engine.

Incorporating these eco-driving habits into your routine can significantly improve your fuel efficiency. Your Kia Soul also comes equipped with an active eco system, which can provide real-time feedback on your driving habits and fuel consumption. This feature can help you understand how your driving habits impact your fuel economy and make necessary adjustments.


Improving the fuel efficiency of your Kia Soul involves a combination of regular maintenance, using the right fuel, and adopting eco-driving habits. By following these steps, you can enhance your fuel economy without compromising the power and performance of your vehicle.

Understanding your vehicle’s fuel-saving features, such as the ECO mode and real-time fuel economy display, can help you make the most of your Kia Soul. Remember, even small changes in your driving habits or maintenance routine can lead to significant savings in fuel costs over time.

So, start today and make your Kia Soul a more fuel-efficient and high-performing vehicle on the road. That way, you’ll not only enjoy a better driving experience but also contribute to a greener, more sustainable world.
