Install the new filter, reconnect the fuel lines, and secure the battery terminal. Test for leaks before driving.
Q4 What should I do if my Subaru Impreza has poor fuel efficiency?
What should I do if my Subaru Impreza has poor fuel efficiency?
If your Subaru Impreza experiences poor fuel efficiency, check for common issues such as low tire pressure, dirty air filters, or clogged fuel injectors. Ensure the engine oil is at the correct level and viscosity. Use a fuel system cleaner to remove deposits. If the problem persists, have a professional inspect the oxygen sensors, spark plugs, and fuel system for potential faults.
Q5 How can I optimize the fuel efficiency of my Subaru Impreza?
How can I optimize the fuel efficiency of my Subaru Impreza?
To optimize fuel efficiency, maintain proper tire pressure, use the recommended grade of motor oil, and avoid excessive idling. Regularly replace air filters and spark plugs.
