The 2012 Subaru Impreza WRX 4-Door requires 5W-30 synthetic oil. The engine oil capacity is approximately 4.5 quarts with a filter change.
Subaru recommends replacing the timing belt every 105,000 miles or 8 years, whichever comes first, for the 2012 Impreza WRX.
Common causes include a loose gas cap, faulty oxygen sensors, or issues with the catalytic converter. A diagnostic scan tool can help identify the specific issue.
Check the spark plugs and ignition coils for wear or damage. Also, inspect the fuel injectors and consider performing a compression test to identify any internal engine issues.
The recommended tire pressure for the 2012 Subaru Impreza WRX is 33 psi for the front tires and 32 psi for the rear tires. Always check the owner's manual or the sticker on the driver's side door jamb for confirmation.
To reset the maintenance light, turn the ignition to the 'ON' position without starting the engine, then press and hold the trip reset button until the maintenance light blinks and turns off.
Use a high-quality phosphate-free, ethylene glycol-based coolant. Subaru's OEM coolant is recommended for optimal performance and compatibility.
To improve fuel efficiency, ensure regular maintenance such as changing the air filter, maintaining proper tire pressure, and using the recommended oil type. Avoid aggressive driving habits and excessive idling.
Signs of a failing clutch include slipping during acceleration, a spongy clutch pedal, difficulty shifting gears, and unusual noises when the clutch pedal is engaged.
To replace the cabin air filter, locate the filter housing behind the glove box. Remove the glove box by detaching the dampener arm and pressing in on the sides. Slide out the old filter and insert the new one, ensuring it is oriented correctly. Reinstall the glove box.
