What is the fuel consumption of a 10-year-old Subaru Forester?
2 Answers
For the 2.5L model with a 4AT transmission from 10 years ago, the pure urban fuel consumption should be around 13. Here is some relevant information about the Subaru Forester: 1. Exterior: The 2009 Forester was equipped with high-brightness LED headlight assemblies, providing better illumination for drivers. Compared to the 2009 Forester sold in Japan, the version introduced to the Chinese market did not have auxiliary rearview mirrors installed. However, features like headlight washers and water-repellent mirrors still offered drivers a sense of the vehicle's user-friendly design. 2. Powertrain and Handling: The 2009 Forester offered two engine options, one being a horizontally opposed 2.0L DOHC 16-valve gasoline engine. 3. Safety Features: The most critical component for vehicle safety is the frame. Subaru developed a new-generation high-strength ring-shaped frame. The cabin underwent specialized reinforcement design, with reinforced sections from the roof to the doors, pillars, and floor pan, all equipped with dedicated support structures to absorb impacts and vibrations from all directions, ensuring cabin safety.
As an experienced mechanic who frequently works on Subarus, the fuel consumption of a 10-year-old Forester depends on its specific condition. The 2.0L models typically consume around 10-12 liters per 100km in city driving with AC on, while highway driving can reduce it to about 8 liters. The 2.5L versions generally consume 1-2 liters more than the 2.0L. From my experience repairing many of these vehicles, sudden increases in fuel consumption usually stem from three issues: carbon buildup on oxygen sensors causing inaccurate fuel injection, aging ignition coils leading to incomplete combustion, and increased resistance from overdue drivetrain fluid changes. Just last week, an owner who replaced all transmission and differential fluids in his decade-old car saw an immediate improvement of over 1L/100km in city driving. Regular carbon cleaning is particularly crucial for these older models, as the horizontally opposed engines are more prone to piston ring sticking.
