25 MPG combined doesn’t immediately scream “fuel sipper,” but for the 2015 Subaru Forester AWD 2.0L, it represents a practical mix of capability and gas mileage. This isn’t a vehicle bought by hypermilers chasing every last tenth of a mile per gallon; it’s a choice made by those who value all-wheel drive confidence, cargo space, and Subaru’s reliable reputation. The fuel economy is simply a number they are willing to accept to get those key features.

City and highway performance

The EPA estimates for the 2015 Forester 2.0L reveal a slightly better highway figure than city, clocking in at 23 MPG in the city and 27 MPG on the open road. This difference reflects the engine’s sweet spot at consistent highway speeds, where the automatic transmission (AV-S8) can settle into its higher gears. The all-wheel-drive system adds weight and complexity that impacts gas consumption, constantly working to efficiently distribute power where it’s needed. In stop-and-go city driving, the Forester’s engine works harder, consuming more fuel as it battles inertia and frequent acceleration. Consider that the “S” in AV-S8 probably means “simulated” steps in the CVT automatic; it’s going to feel different than a conventional automatic for fuel-conscious drivers.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2015 Subaru Forester 2.0L is $2,300. This figure is based on driving 15,000 miles per year and using national average fuel prices. It’s a useful benchmark for comparison, but keep in mind that actual costs will vary depending on individual driving habits, local fuel prices, and even the type of gasoline used. If you routinely drive aggressively, spend a lot of time in stop-and-go traffic, or live in an area with higher-than-average fuel costs, your annual expenditure will likely exceed this estimate.

Real-world expectations

While the EPA estimates provide a standardized baseline, real-world fuel economy can often differ. Forester owners report achieving figures close to the EPA’s estimates, but results depend on driving style and conditions. Drivers who stick to moderate speeds on the highway and avoid aggressive acceleration can often match or even slightly exceed the 27 MPG highway figure. However, consistently pushing the engine or driving in demanding conditions will naturally reduce fuel economy.

Owners who monitor their gas consumption closely often find that regular maintenance, such as keeping tires properly inflated and ensuring the engine is properly tuned, contributes to better overall efficiency.

How it compares

The 2015 Forester’s fuel economy positions it competitively within its class, but specific comparisons depend on the priorities of the buyer. A comparable Honda CR-V from the same year, with its 2.4L engine and front-wheel drive, boasts 29 MPG combined. A Toyota RAV4, another popular choice, achieves around 25 MPG combined in its front-wheel drive configuration. all Subaru fuel economy data shows that the Forester pays a small fuel penalty for its standard all-wheel-drive system. If all-weather capability is non-negotiable, the Forester’s fuel economy is a reasonable trade-off. However, for those primarily concerned with maximizing MPG in dry climates, a front-wheel-drive competitor might present a more economical option. A Mazda CX-5 with its 2.0L engine and front-wheel drive can achieve up to 29 MPG combined in specific trims. It’s worth cross-shopping even today, checking FORESTER MPG across all years.

Tips to maximize efficiency

Gentle acceleration and anticipation of traffic flow are key to maximizing fuel economy in the 2015 Forester. Avoid abrupt starts and stops, and maintain a steady speed whenever possible. Gradually increasing speed allows the engine to operate more efficiently, particularly at highway speeds.

Proper tire inflation plays a critical role in fuel efficiency. Check your tire pressure regularly and inflate them to the recommended levels. Underinflated tires create more rolling resistance, which can significantly reduce fuel economy. The recommended tire pressure is found on the driver’s side door jamb.

Minimize the use of accessories that draw power from the engine. Air conditioning, especially in hot climates, can significantly increase fuel consumption. Use it sparingly and consider opening windows when appropriate. Relying on accessories puts strain on the engine and decreases your overall mileage.

Regular maintenance is essential for maintaining optimal fuel economy. Ensure that your Forester’s engine is properly tuned and that all scheduled maintenance is performed on time. This includes oil changes, air filter replacements, and spark plug replacements. A well-maintained engine runs more efficiently and consumes less fuel.
