The 2012 Subaru Impreza comes equipped with the FB20 2.0-liter naturally aspirated flat-four engine, producing 148 horsepower and 145 lb-ft of torque. This was the first year for Subaru’s new FB engine series, replacing the previous EJ25 in base Imprezas. The FB20 features an aluminum block and heads, direct injection, and active valve control system for improved fuel economy. It’s paired with either a 5-speed manual transmission or Subaru’s Lineartronic CVT. The engine runs on regular 87-octane gasoline and achieves EPA ratings of up to 36 mpg highway when equipped with the CVT transmission.

The 2012 Subaru Impreza shares most parts with 2012-2016 Impreza models, as this generation ran through 2016. The FB20 engine components are largely interchangeable across these years, though there were minor updates in 2014 and 2015. Body panels, interior components, and suspension parts generally interchange within the 2012-2016 range. However, the 2017+ models represent a completely new generation with different body panels and some mechanical changes. CVT transmissions from 2012-2014 are most compatible, while 2015-2016 CVTs received updates. Always verify part numbers for electrical components, as there were running changes throughout production.

The FB20 2.0L engine in the 2012 Impreza is generally more reliable than previous Subaru engines, with fewer head gasket issues that plagued earlier models. However, early production engines (2012-2014) can suffer from excessive oil consumption, which Subaru addressed through extended warranties and updated piston rings in later production. The engine responds well to regular maintenance with full synthetic oil changes every 6,000 miles. Timing chain replacement is typically needed around 150,000-200,000 miles. Overall, with proper maintenance and monitoring oil levels, the FB20 can provide reliable service well beyond 200,000 miles, though the CVT transmission is often the limiting factor in these vehicles.
