While slightly lower than the naturally aspirated engine, it still offers competitive fuel efficiency for its class, especially considering the added performance.

Previous Generation Outback MPG (2015-2019)

Models from the fourth generation (2015-2019) also offered similar engine choices, with slight variations in MPG ratings. The standard 2.5-liter engine generally achieved around 25 MPG city / 32 MPG highway / 28 MPG combined. The optional 3.6-liter 6-cylinder engine, while offering more power, was less fuel-efficient, typically rated around 20 MPG city / 27 MPG highway / 22 MPG combined.

Older Outback Models (Pre-2015)

Fuel economy for Outbacks prior to the 2015 model year can vary more significantly. Generally, older models with larger engines or less advanced engine management systems will exhibit lower MPG figures. For example, a 2010 Outback with the 2.5-liter engine might achieve figures closer to 22 MPG city / 29 MPG highway / 25 MPG combined.

Factors Influencing Subaru Outback Gas Mileage

While EPA estimates provide a benchmark, your real-world Subaru Outback gas mileage can be influenced by several factors. Understanding these can help you manage expectations and improve your driving habits.

Driving Habits

Aggressive driving, such as rapid acceleration and hard braking, significantly reduces fuel efficiency. Smooth, consistent acceleration and anticipating stops can lead to substantial MPG improvements. According to the U.S. Department of Energy, aggressive driving can decrease MPG by as much as 33% on the highway and 5% in city driving. — Convert 2.13 Meters To Feet: A Simple Guide

Driving Conditions

• City vs. Highway: Highway driving is generally more fuel-efficient due to consistent speeds and less stop-and-go traffic. City driving, with its frequent stops and idling, will naturally yield lower MPG figures.
• Terrain: Driving on hilly or mountainous terrain requires more engine power, consuming more fuel compared to flat surfaces.
• Traffic: Heavy traffic and stop-and-go conditions significantly decrease fuel economy. Idling, in particular, burns fuel without covering any distance.

Vehicle Maintenance

Regular maintenance is crucial for optimal engine performance and fuel efficiency. Key maintenance items include:

• Tire Pressure: Underinflated tires increase rolling resistance, forcing the engine to work harder. Regularly check and maintain proper tire pressure as recommended by Subaru.
• Engine Tune-Up: Ensuring spark plugs, filters (air and fuel), and other engine components are in good condition helps the engine run efficiently.
• Oil Changes: Using the recommended grade of oil can improve engine lubrication and reduce friction, contributing to better MPG.

Vehicle Load and Aerodynamics

• Weight: Carrying excessive weight in your Outback requires more energy to move, thus consuming more fuel. Emptying unnecessary items from your vehicle can help.
• Roof Racks/Carriers: External accessories like roof racks, cargo boxes, or bike racks can disrupt the vehicle's aerodynamics, increasing drag and reducing fuel economy, especially at higher speeds.

Environmental Factors

• Temperature: Cold weather can reduce MPG. Engines are less efficient when cold, and the use of heating systems consumes additional energy.
• Fuel Quality: While less common, variations in fuel quality can sometimes impact performance and efficiency.

Tips for Improving Your Subaru Outback's Fuel Economy

Maximizing your Subaru Outback gas mileage isn't just about buying the most efficient model; it's also about smart driving and maintenance. Here are some actionable tips:

Drive Smarter

• Maintain Steady Speeds: Use cruise control on the highway whenever possible to maintain a consistent speed.
• Anticipate Traffic: Look ahead and anticipate slowdowns or stops to avoid unnecessary braking and acceleration.
• Limit Idling: Turn off your engine if you expect to be stopped for more than 30 seconds.
• Combine Trips: Plan your errands to make fewer, more efficient trips, reducing cold starts.

Maintain Your Vehicle

• Regular Inspections: Follow Subaru's recommended maintenance schedule for your Outback. This includes oil changes, filter replacements, and checking all fluid levels.
• Tire Care: Check your tire pressure monthly and before long trips. Proper inflation can improve MPG by up to 3% according to the U.S. Department of Energy.
• Wheel Alignment: Ensure your wheels are properly aligned to prevent uneven tire wear and reduce rolling resistance.

Reduce Drag and Weight

• Remove Unused Accessories: Take off roof racks or cargo carriers when they are not in use.
• Lighten the Load: Regularly clear out unnecessary items from your trunk and cabin.

Consider Your Tires

• Low Rolling Resistance Tires: When it's time to replace your tires, consider models designed for low rolling resistance. These can offer a slight improvement in fuel economy.
