How To Fix High Subaru Fuel Consumption

Fuel consumption issues can be frustrating and costly, especially if your Subaru is consuming more gas than expected. High fuel consumption can be caused by a variety of factors, from poor maintenance to driving habits. At Empire Subaru, we’ll guide you through some of the most common causes of high fuel consumption and how to address them.

1. Check Your Tire Pressure

One of the most overlooked reasons for high fuel consumption is low tire pressure. When your Subaru’s tires are under-inflated, they create more rolling resistance, which makes the engine work harder and consume more fuel. It's essential to keep your tires properly inflated to ensure optimal fuel efficiency.

To fix this, check the tire pressure regularly using a tire pressure gauge, and make sure the pressure matches the recommended levels listed in your owner’s manual or on the label inside your driver’s side door. At Empire Subaru, we offer tire maintenance services to keep your Subaru’s tires in top condition.

2. Replace Clogged Air Filters

A clogged or dirty air filter can reduce your Subaru’s fuel efficiency. The air filter prevents dirt and debris from entering the engine, but if it becomes clogged, the engine struggles to breathe properly, which leads to inefficient fuel combustion.

To fix this, replace your air filter at regular intervals. If you haven’t replaced it in a while, it might be time for a new one. A clean air filter ensures that your engine receives the proper amount of airflow, helping to improve fuel efficiency. Our service team at Empire Subaru can help you replace your air filter during your next visit.

3. Change Your Spark Plugs

Worn-out or dirty spark plugs can contribute to poor fuel economy. Spark plugs ignite the fuel in the engine, and if they aren’t functioning properly, fuel combustion can become less efficient. This causes the engine to use more fuel to produce the same amount of power.

If your spark plugs are overdue for replacement, it’s essential to change them to maintain optimal fuel efficiency. Regularly replacing your spark plugs, as part of routine maintenance, helps your engine run more smoothly and efficiently.

4. Perform Regular Oil Changes

Using old, dirty oil in your Subaru can increase friction in the engine, causing it to work harder and use more fuel. Regular oil changes are essential to keeping the engine lubricated and operating smoothly. Old oil can also lead to engine wear and other performance issues.

Make sure you change the oil in your Subaru at the recommended intervals to ensure your engine is running efficiently. At Empire Subaru, our experienced technicians can help you with timely oil changes to keep your vehicle running at its best.

5. Drive Smoothly and Avoid Rapid Acceleration

Your driving habits play a significant role in your Subaru’s fuel consumption. Aggressive driving, such as rapid acceleration and harsh braking, can reduce fuel efficiency. By driving more smoothly and avoiding sudden starts and stops, you can improve your vehicle’s fuel economy.

Try to maintain a steady speed, especially on highways, and anticipate stops to avoid heavy braking. This will not only save you fuel but also reduce wear and tear on your car’s brakes and engine.

High fuel consumption in your Subaru can be caused by a number of factors, from tire pressure to driving habits. By addressing these issues, such as maintaining your tires, replacing clogged filters, and driving smoothly, you can improve your Subaru’s fuel efficiency.
