Is the Subaru Forester 2010 fuel efficient?

The 2010 Subaru Forester offers reasonable fuel efficiency for its segment and era, with EPA estimates generally in the mid-20s mpg in city driving and the high-20s to low-30s mpg on the highway, depending on engine and transmission.

The efficiency of the 2010 Forester varies notably by the chosen engine and transmission. Subaru offered a naturally aspirated 2.5-liter four-cylinder in several trims, plus a turbocharged 2.5-liter in the XT model, with either a conventional automatic, a manual, or a continuously variable transmission (CVT) where available. All-wheel drive is standard or widely used in this model year, which provides traction but can slightly temper fuel economy versus front-wheel-drive rivals. Real-world mileage also depends on maintenance, tires, load, and driving style.

Fuel economy by drivetrain

EPA estimates for the 2010 Forester vary by engine and transmission. The following ranges give a sense of what owners could expect in typical driving.

• 2.5-liter naturally aspirated engine with a 4-speed automatic: about 20 mpg city / 26 mpg highway


• 2.5-liter naturally aspirated engine with a 5-speed manual: about 19 mpg city / 25 mpg highway


• 2.5-liter naturally aspirated engine with CVT (available on some trims): about 22 mpg city / 28–29 mpg highway


• 2.5XT turbocharged engine (XT model) with automatic or CVT: about 18–20 mpg city / 25–28 mpg highway

These figures reflect the 2010 model year when the Forester offered multiple powertrains and transmission choices. In practice, highway driving tends to yield the best efficiency, especially with a CVT, while city driving and heavy loads or frequent acceleration can push mpg lower. All-wheel drive adds capability but can reduce city and highway mileage slightly compared with front-wheel-drive designs.

Real-world factors and tips to maximize efficiency

Several practical factors influence actual fuel economy on a 2010 Forester. Tires, maintenance, and load play significant roles, as does driving style. Below are key considerations and simple steps to squeeze a bit more efficiency from the vehicle.

• Keep tires inflated to the recommended pressure; underinflated tires raise rolling resistance and reduce mpg.


• Follow a regular maintenance schedule, including air filter and spark plug replacement, and use the recommended grade of motor oil.


• Consider driving the CVT-equipped trims for better highway fuel economy, especially on longer trips.


• Limit roof rack use and heavy payload when you don’t need it, as aerodynamics and weight affect efficiency.


• Plan efficient routes and smooth acceleration/braking habits to maximize mpg in daily driving.

In summary, the 2010 Forester can be quite efficient for a compact SUV of its time, particularly with the non-turbo 2.5L engine paired with a CVT. The turbo XT and traditional automatics may show lower real-world mileage, especially in city driving. For precise numbers, consult the EPA window sticker for your exact trim and transmission.

Summary

Overall, the 2010 Forester offers competitive fuel economy within its class for its era, with the best efficiency typically found in the CVT-equipped, non-turbo models and somewhat lower figures for the turbocharged XT and manual transmissions. Real-world results will vary based on maintenance, tires, load, and driving style, but the Forester remains a practical choice for those prioritizing all-weather capability alongside respectable fuel efficiency.

Is a 2010 Subaru Forester good on gas?

The Forester is equipped with a 2.5-liter four-cylinder engine with single overhead cam rated at 170 horsepower. Fuel economy is an EPA-estimated 20/26 mpg City/Highway with automatic transmission.

How long will a 2010 Subaru Forester last?

A 2010 Subaru Forester can last between 200,000 and 250,000 miles with proper maintenance, and many can exceed 300,000 miles. Key factors include regular oil changes, servicing the AWD system, and addressing potential head gasket issues, which were common in this era. With consistent care, it can be a very long-lasting vehicle. 
How to maximize its lifespan

• Regular maintenance: Adhere to the recommended maintenance schedule, especially for oil changes and checking CVT fluid. 
• Head gasket replacement: If the head gaskets haven't been replaced, consider doing so. This is a common failure point for this model and a preventative replacement can help you reach 200,000 miles or more. 
• Drive and climate: Driving style and location can impact longevity. A consistent, gentle driving style (especially on highways) and avoiding harsh climates will help preserve the engine and other components. 
• Address other potential issues: Be aware of other potential problems like catalytic converter failure or worn spark plug wires, and address them promptly to prevent further damage. 

What to expect

• Potential for high mileage: With proper care, reaching 200,000 miles is achievable, and some can go much further. 
• Cost of repairs: At this age, some wear and tear is inevitable. Be prepared for potential repairs or replacements as the vehicle gets older. 

Is a Subaru Forester good on fuel?

Yes, the Subaru Forester is generally considered fuel-efficient, especially for an SUV with standard all-wheel drive. Recent models achieve an EPA-estimated 26 mpg in the city and 33 mpg on the highway, though specific figures can vary slightly by trim. 

• Standard All-Wheel Drive: The Forester gets its good mileage while still providing all-wheel drive as standard, which is often a feature that lowers fuel economy in other vehicles. 
• Trim-Level Variation: Most trim levels offer the same 26 city/33 highway mpg, with slightly lower ratings for trims like the Sport, Touring, and Wilderness. 
• Competitive Fuel Economy: The Forester's fuel efficiency is competitive within the compact SUV segment. 
• Factors Affecting MPG: Real-world mileage can be affected by driving habits, terrain, and vehicle maintenance. 

What are common problems with a 2010 Subaru Forester?

Common problems with the 2010 Subaru Forester include head gasket issues, timing belt concerns, and oil consumption, especially on older models, although improvements were made around this time. Other issues reported include a faulty front oxygen sensor, catalytic converter failure, and potential problems with the AC compressor or wheel bearings. Rust around the rear wheel wells and cracking interior parts like the center console can also be an issue.
 
Engine and performance

• Head gaskets: The head gasket is a known weak point, with potential leaks and overheating issues. If the head gasket has been replaced with an upgraded version, it should be a one-time fix. 
• Timing belt: The timing belt is also a common maintenance item. If the head gasket was replaced, the timing belt was likely done as well. 
• Oil consumption: Some models may experience excessive oil consumption. 
• Catalytic converter: The catalytic converter can fail, triggering a check engine light. 
• Front oxygen sensor: A front oxygen (air-fuel ratio) sensor can crack, illuminating the check engine light. 

Electrical and mechanical

• AC compressor: The AC compressor can fail, requiring an expensive repair. 
• Wheel bearings: Like other Subaru models, the Forester can be prone to wheel bearing issues, especially in areas with snow and salt. 
• Transmission: Some automatic transmission models may exhibit trembling, especially at higher speeds. 

Body and interior

• Rust: Look for rust, particularly around the rear wheel wells, especially if the car is from a region with harsh winters.
• Interior trim: The center console cubby door and its latch can be prone to cracking.
• Window seals: The frameless windows can have torn window gussets, which may lead to wind noise.
